Takeaways

  • 📈 特斯拉股价在2024年上半年经历了剧烈波动,从年初的约250美元下跌至4月的140美元低点,随后在7月回升至250美元。
  • 🚀 特斯拉在过去六个月中面临诸多挑战,包括高管辞职、Model 2的传闻、Elon Musk的筹资计划被拒以及超级充电团队的裁员等。
  • 🔍 市场对特斯拉的负面报道和怀疑不断,导致许多自称长期投资者的人改变立场,选择在低点抛售并批评特斯拉。
  • 🎢 特斯拉股东大会是上半年投资战场的高潮,Elon Musk的新筹资计划和公司总部迁移至德克萨斯州的投票带来了极大的不确定性。
  • 🗳️ 投票结果以压倒性优势通过,消除了之前的疑虑,表明Elon Musk得到了大多数投资者的支持,并承诺将特斯拉打造成地球上最有价值的公司。
  • 📚 投资中的信号与噪声比是一个重要概念,即有用信息与无关信息的比例。提高这个比例意味着从信息中提取了更多有用内容。
  • 📊 频繁观察数据会导致接收到的噪声增多,信号与噪声比降低,因此经验丰富的投资者提醒我们关注长期而非日常股价波动和新闻。
  • 🤔 投资者不应将信息误认为信号,真正需要的是信息中的有用信号。获取这些信号需要重视信息来源的质量和自身从信息中提取信号的能力。
  • 📚 投资者应通过阅读书籍学习投资和行业的基础知识,以及技术的核心知识,而不是沉浸在消费他人的观点中。
  • 🧐 投资个股相较于指数基金更容易让我们处于不利地位,因为个股的股价波动更剧烈,导致投资者更频繁地观察数据,从而降低了信号与噪声比。
  • 🌐 投资信号和噪声具有上下文相关性,不同的投资目标、周期、市场环境甚至不同的投资者,他们面临的信号和噪声都是不同的。

Q & A

  • 2024年上半年特斯拉的股价经历了怎样的波动?

    -2024年上半年特斯拉的股价从年初的大约250美元持续下跌,4月份跌至140美元以上的最低点,然后在7月份回升至年初的大约250美元水平。

  • 特斯拉在过去六个月中经历了哪些重大事件?

    -特斯拉在过去六个月中经历了高管辞职、Model 2被传闻取消后又提前推出、Elon Musk的新筹资计划被法院拒绝、超级充电团队被裁员等一系列事件。

  • 为什么说特斯拉的股东大会是一次关键的决策时刻?

    -特斯拉的股东大会是关键的决策时刻,因为它涉及到Elon Musk的新筹资计划和公司总部迁移到德克萨斯州的投票,这些决策对公司的未来有着重大影响。

  • 为什么说投资者在股东大会前的不确定性或恐慌是不必要的?

    -因为最终投票结果以压倒性多数通过,之前所有的疑虑和恐慌都被证明是不必要的,这表明大多数投资者仍然支持Elon Musk和特斯拉。

  • 什么是信号与噪声比,它在投资中的重要性是什么?

    -信号与噪声比是指有用信息与无关信息的比例。在投资中,一个高的信号与噪声比意味着从信息中提取了更多有用的内容,而低的比率则意味着更多的无关信息,真正有用的信息被掩盖了。

  • 为什么频繁观察数据会导致信号与噪声比降低?

    -频繁观察数据会导致接收到的噪声增多,因为日常或每小时的数据观察会大幅增加噪声的比例,而真正有用的信号所占比例则大幅减少。

  • 为什么说更多的信息并不一定意味着更好的投资决策?

    -因为投资者真正需要的是信息中的有用信号,而不是信息本身。过多的信息如果没有经过筛选和理解,可能会降低投资的信号与噪声比,导致投资决策的质量下降。

  • 为什么说投资指数基金相比投资个股在信号与噪声比上更有优势?

    -投资指数基金的投资者默认心态是长期持有,这无形中延长了数据观察的时间跨度,减少了观察频率,且指数基金的日波动相对较低,这在投资心理上给投资者带来了优势。

  • 为什么说投资个股比投资指数基金更容易受到噪声的影响?

    -投资个股的信号更加动态和多变,股价经常剧烈波动,这会导致投资者感受到不确定性,自然会增加获取信息的频率,从而降低了信号与噪声比。

  • 为什么说投资决策应该基于个人的上下文来定义信号和噪声?

    -因为不同的投资者有不同的个人情况,包括风险承受能力、资金分配、心理承受力等,因此投资者应该根据自己的具体情况来定义对自己有用的信号和噪声,而不是简单地采纳他人的信号。

  • 为什么视频作者决定停止增加特斯拉的持股?

    -视频作者决定停止增加特斯拉的持股,因为他的平均购买价格已经达到了他设定的目标价格65美元/股,这个价格反映了他个人的多种考虑,包括安全边际、仓位比例、风险控制等。

📉 特斯拉股价的过山车之旅与投资信号

2024年上半年,长期投资者在特斯拉的投资体验如同过山车。视频总结了这段经历,并提出了投资中的四个重要原则,包括信号与噪声的概念。作者分享了自己作为长期投资者在过去两年持续买入特斯拉股票后,决定停止增持的原因。提到了特斯拉股价从年初的约250美元跌至4月的140多美元,再到7月回到250美元的水平。期间,特斯拉经历了高管辞职、Model 2的传闻、Elon Musk的筹资计划被拒、超级充电团队裁员等一系列动荡事件,市场对特斯拉的负面报道和怀疑不断。许多自称长期投资者的人也纷纷改变立场,选择在低点卖出并批评特斯拉。6月13日的股东大会是这场投资战的高潮,Elon Musk的新筹资计划和公司总部迁移到德克萨斯州的投票,最终以压倒性多数通过,消除了之前的疑虑。

05:00

📚 投资中的信号与噪声:提高信号比率的重要性

投资中的信号与噪声比率是关键概念,即从信息中提取有用内容的比例。视频通过《反脆弱》一书中的例子,说明了观察数据频率的增加会导致噪声比例上升,有用信号的比例下降。作者强调,要提高信号比率,需要减少噪声的影响,并理解四个重要原则。首先,信息的来源非常重要,一手信息远比二手信息可靠。其次,投资者需要有能力从信息中提取信号,这需要通过学习投资和行业的基础知识来实现。此外,投资个别股票相比于指数基金更容易受到噪声的影响,因为股票价格的波动性更大,投资者的心理不确定性也更高。

10:03

🤔 投资决策中的信号与噪声:个人投资经历分享

作者分享了自己在2024年上半年对特斯拉股票的投资经历,以及如何根据个人情况定义投资信号和噪声。提到了特斯拉股东大会上Elon Musk的新计划和公司总部迁移的投票,虽然这些事件看似与公司基本面无关,但对投资者信心和市场叙事有重大影响。作者认为,即使是短期事件,也可能成为影响公司长期价值的重要信号。此外,作者提到了自己在2018年底开始投资特斯拉,并在2020年5月Elon Musk推文后停止增持,然后在2022年初股价下跌时重新开始增持,直到平均价格达到65美元时停止。

15:03

🛑 投资信号的个人化:为何我决定暂停增持特斯拉股票

作者解释了自己为何决定暂停增持特斯拉股票,强调了投资信号的个人化和上下文的重要性。提到了个人投资目标的设定,包括安全边际、仓位比例、风险控制、心理承受能力、家庭资产配置、税务考虑以及个人年龄和健康状况等因素。作者提醒观众,每个人的投资情况都是独特的,不能简单地将他人的投资决策作为自己的信号。最后,作者表达了对未来是否增持特斯拉股票的不确定性,这将取决于个人情况的变化。

If you are a long-term investor in Tesla

play00:01

Then the first half of 2024

play00:02

Will definitely feel like a roller coaster ride

play00:04

So today I want to make a video to summarize

play00:06

What the past six months of investing in Tesla has taught us

play00:08

about the four important principles of signal and noise

play00:11

Finally, I will share why I

play00:13

as a long-term investor in Tesla

play00:14

have been continuously buying over the past two years

play00:17

Decided to stop increasing Tesla holdings

play00:19

Here is Tesla's stock price trend over the past six months

play00:22

From around 250 at the beginning of the year

play00:23

It kept falling to the lowest point of over 140 in April

play00:26

So now in July

play00:27

It has returned to around 250, the level at the beginning of the year

play00:29

In the past six months

play00:31

Tesla has been in constant turmoil

play00:32

Executives resigning

play00:33

Model 2 was rumored to be canceled and then brought forward

play00:36

Elon's new fundraising plan was rejected by the court

play00:38

The Supercharger team was laid off and a series of other events

play00:41

Bringing countless suspense

play00:43

The market is full of

play00:44

negative reports and doubts about Tesla

play00:46

Many so-called long-term investors of Tesla

play00:48

have also changed their stance one after another

play00:49

choosing to sell at a low point and criticize Tesla

play00:52

The investment scene of Tesla in the past six months

play00:54

Comparing it to a battlefield is not an exaggeration at all

play00:56

And this final battle

play00:57

I'm afraid it's the June 13th shareholders' meeting

play01:00

Elon's new fundraising plan

play01:01

and the vote to move the company headquarters to Texas

play01:03

Before the vote

play01:05

Tesla investors felt that kind of

play01:06

extremely high uncertainty

play01:08

Or even panic

play01:09

We gradually let some ideas germinate in our minds

play01:12

Will the vote pass?

play01:14

Are Tesla's investors divided?

play01:16

Will Elon take AI away from Tesla?

play01:19

But everyone knows the final result

play01:20

The vote passed overwhelmingly

play01:22

What about those previous doubts

play01:23

All were completely dispelled

play01:24

Elon Musk also received an important signal

play01:26

That is, he has the support of most investors

play01:29

He also promised to make Tesla into

play01:31

The most valuable company on Earth

play01:33

So this matter

play01:34

actually taught us a lesson

play01:36

that all the previous drama and thoughts

play01:38

Most of it is just noise

play01:40

We only need to see a small portion of people

play01:43

Speaking loudly can create enough noise

play01:45

Make you feel panic

play01:47

Even sell your stocks at a low point

play01:49

But here is a problem

play01:50

Looking back at these now

play01:52

We only realize

play01:53

That most of what we heard and saw was noise

play01:55

But when we are in the midst of the whirlpool

play01:58

How can we distinguish the noise

play02:00

And avoid its impact?

play02:02

I think to achieve this

play02:03

you first need to understand the concept of signal-to-noise ratio in investment

play02:07

The so-called signal-to-noise ratio simply means

play02:09

Useful information

play02:10

That is, the ratio of signal to irrelevant information

play02:12

We call it the noise ratio

play02:14

The higher the signal-to-noise ratio

play02:15

It means that from the information

play02:16

You have extracted more useful content

play02:18

Conversely, the lower the signal-to-noise ratio

play02:19

It means more irrelevant information

play02:21

Truly useful information is obscured

play02:23

To improve this signal-to-noise ratio

play02:25

Reduce the impact of noise

play02:26

You need to understand the following four important principles

play02:29

In this book Antifragile

play02:31

The author Taleb presents a very interesting phenomenon

play02:34

That is, as we increase the frequency of observing data

play02:37

The more noise we get

play02:41

The lower the signal-to-noise ratio

play02:42

The author says this is not a psychological phenomenon

play02:45

It more accurately reflects the essential characteristics of the data

play02:48

He gave an example

play02:49

Suppose you observe on a yearly basis

play02:51

Data of a stock

play02:52

If the signal-to-noise ratio is 1:1

play02:54

Then when you increase the observation period

play02:56

When observing every day

play02:58

The proportion of noise will suddenly increase to 95%

play03:01

And the proportion of truly useful signals is only 5%

play03:04

If you change the observation period to hours

play03:07

Noise will account for 99.5%

play03:09

The signal is only 0.5%

play03:10

The noise is nearly 200 times the signal

play03:13

Actually, this is also why countless experienced people

play03:15

Remind us to focus on the long term

play03:18

Instead of daily stock price fluctuations and news

play03:20

Because this frequent observation

play03:21

Will lead to what we hear and see

play03:23

The vast majority is noise

play03:25

So let's reflect again

play03:27

The experience of Tesla investors in the first half of the year

play03:29

Many people follow stock prices every day, even every hour

play03:33

They look at others' analyses and opinions

play03:35

They follow various news and rumors

play03:37

This not only doesn't help

play03:38

Instead, it puts you at a disadvantage

play03:41

Because your signal-to-noise ratio is greatly reduced

play03:43

The noise you receive is

play03:45

Others who don't pay much attention to daily updates

play03:47

Long-term investors multiply their investments several to dozens of times

play03:49

It is no exaggeration to say

play03:50

For most investors

play03:52

Watching the news trends every day

play03:54

Not only wasting time

play03:56

But also hurting yourself

play03:58

Second

play03:58

Don't mistake information for signals

play04:01

Many of us have a misconception

play04:03

That more information is better

play04:05

Mastering comprehensive information

play04:07

Means mastering the whole truth

play04:09

Will help you make investment decisions

play04:11

More confident

play04:11

But actually what you need is not information

play04:15

But the useful signals within the information

play04:17

So how can we better obtain these signals?

play04:19

First, the source of information is very important.

play04:21

Primary information is far more reliable than secondary information

play04:24

For example, the company's financial reports and meetings

play04:26

Accurate and objective statistical data

play04:28

CEO

play04:29

Executives

play04:29

Technical Team

play04:30

Even employees' speeches and interviews

play04:32

These are all very good materials

play04:33

Although I am a YouTuber

play04:34

But I want to say

play04:35

Information provided by YouTuber

play04:37

Most are not first-hand materials

play04:39

The so-called summaries and interpretations we do

play04:41

Often have significant limitations

play04:43

No one can be completely objective

play04:45

Everyone will mix in their own preferences and perspectives

play04:47

If your information mainly comes from YouTubers

play04:50

or some opinions and emotions on social networks

play04:52

Then you are inadvertently lowering your investment signal-to-noise ratio

play04:56

To obtain useful signals

play04:58

Having only high-quality information sources is still not enough

play05:00

You also need the ability to extract signals from the information

play05:03

If you don't have this ability

play05:04

Even the best sources of information are useless

play05:05

This is why many people bypass first-hand information

play05:08

Rely on second-hand information sources like us YouTubers

play05:11

When you can't extract the signal yourself

play05:14

You can only rely on others to tell you the conclusion

play05:16

But the signal others give you may not only be unreliable

play05:19

Because it has not gone through your own understanding and processing

play05:22

The conclusions you obtain are also not solid

play05:24

You do not truly believe these conclusions

play05:26

When you face uncertainty

play05:28

You will still be swaying and at a loss

play05:31

So how should we acquire the ability to filter signals from information?

play05:36

The answer is go fundamental

play05:38

Go learn the basics

play05:39

By reading books to learn about investment and industry

play05:42

Even the most essential knowledge of technology

play05:44

Instead of immersing oneself in consuming others' opinions

play05:48

I made a video a long time ago

play05:49

Recommended some investment books

play05:51

Suggest you take a look

play05:52

Should be helpful to you

play05:54

Additionally, I would like to remind you

play05:55

Besides those basic knowledge

play05:57

As an investor

play05:58

You also need to continuously learn about the cutting-edge technology in your investments

play06:02

For example, if you invest in AI and robots

play06:05

Then you really need to read a few related books

play06:08

Understand their historical principles and future development directions

play06:11

Be a good investor

play06:13

First, you must be a good learner

play06:16

Third

play06:17

In this newly created war

play06:19

Investing in individual stocks makes it easier to put us at a disadvantage

play06:22

Regular viewers of mine all know

play06:23

I only have two investments in the stock market

play06:25

One is Tesla

play06:26

One is an index fund

play06:28

They are two completely different investment approaches

play06:30

Over the years

play06:31

In terms of the signal-to-noise ratio in investment

play06:34

These two investments have given me completely different experiences

play06:37

Here, I will make a simple comparison for everyone

play06:39

Most investors who choose index funds

play06:42

Default mindset is long-term holding

play06:44

This invisibly extends the time span of our data observation

play06:48

Reduced the frequency of observation

play06:50

Although many people still check the performance of index funds daily

play06:54

But everyone is very clear

play06:55

What really matters is at least a few months

play06:58

or even the trend over several years

play06:59

More importantly

play07:00

Because the daily fluctuations of the index are relatively low

play07:03

This gives us a great advantage in investment psychology

play07:06

In the investment summary video at the end of last year

play07:08

I shared this book

play07:10

The Uncertainty Solution

play07:12

The book mentions an important psychological phenomenon

play07:14

It is human nature to crave certainty

play07:16

When filled with uncertainty

play07:18

We can easily become information hoarders

play07:21

We hope to obtain a large amount of information

play07:23

to get a definite answer

play07:25

when stock prices fluctuate wildly

play07:26

People feel more uncertain

play07:28

So they can't control themselves to get more information

play07:32

Increase the frequency of observing data

play07:34

Leading to a reduction in the signal-to-noise ratio

play07:35

When investing in index funds

play07:37

Except for very rare moments

play07:39

Most of the time its fluctuations are not severe

play07:41

So people are not easily trapped in psychological uncertainty

play07:45

To seek more information

play07:47

In contrast, investing in stocks like Tesla

play07:49

Although many people, like me, hold it for the long term

play07:51

But because the stock price often fluctuates violently

play07:53

Investors will feel uncertainty

play07:56

Naturally, it will far exceed index funds

play07:58

Our human instincts will prompt us to check stock prices daily

play08:01

To obtain at a faster frequency

play08:03

More information related to this stock

play08:05

This greatly reduces our signal-to-noise ratio

play08:07

This situation not only happens to Tesla investors

play08:09

Investors of any individual stock will face similar situations

play08:12

Another reason why investing in individual stocks is more likely to get noise is

play08:16

The investment signals of individual stocks are more dynamic and variable compared to index funds

play08:19

More dynamic and variable

play08:21

This leads to investors wanting to obtain reliable and useful signals

play08:25

It becomes more difficult

play08:26

Let's take index funds as an example

play08:28

When investing in index funds

play08:30

Our signal can be the overall economic trend

play08:32

People's expectations for the future economy

play08:34

The overall earnings trend of all companies, etc

play08:37

I can't say that these macro trends are easier to judge

play08:40

But we know very clearly

play08:42

Which indicators we should look at

play08:44

Even many index fund investors

play08:45

will not look at these indicators

play08:47

because they choose index funds

play08:49

The primary reason is their optimism about the long-term economy

play08:52

Once your dimension becomes very long

play08:54

The signals you need will be extremely reduced and simplified

play08:57

There are about 500 companies in the sample of 500

play08:59

Index investors don't need to worry

play09:01

about a company's financial report

play09:03

or the CEO's political inclinations

play09:05

What outrageous words did he say today

play09:06

Who did he have a child with tomorrow

play09:07

Or is he healthy

play09:09

But when we invest in individual stocks like Tesla

play09:12

Even if you are a long-term investor

play09:14

The signals you need to observe

play09:16

It is often dynamic and changeable

play09:17

Let's take the Tesla shareholder meeting

play09:20

For example, the vote on Elon's new plan and the company headquarters relocation

play09:23

As a long-term investor

play09:25

Should you pay attention to such a specific event

play09:28

On one hand, you could consider it as noise

play09:30

Because it doesn't have that much to do with the company's fundamentals

play09:33

Even if the vote doesn't pass

play09:35

Elon Musk will not leave

play09:36

It is also impossible to take Tesla's AI and data away

play09:40

Elon is just simply "threatening the shareholders"

play09:42

You can even think

play09:43

Even if Elon Musk leaves

play09:45

Tesla can still develop well according to the established route

play09:48

The short-term stock price fluctuations are not worth paying attention to

play09:51

On the other hand

play09:52

You can also think of this voting turmoil as not just noise

play09:54

But as a real signal

play09:56

Even I agree

play09:57

In any case, Elon can't leave

play09:59

But when the public opinion and attention surrounding this voting controversy

play10:02

When it is big enough

play10:03

It will affect the judgment of most investors

play10:05

It can even change the market

play10:07

The narrative and confidence in this company and stock

play10:10

When the people of a country lose confidence in the economy

play10:12

It can lead to deflation

play10:14

The vicious cycle of economic stagnation

play10:16

This is even more true for a company

play10:18

When most Tesla investors

play10:20

Tesla's employees and the media

play10:22

both have doubts and distrust towards this company and Elon Musk

play10:23

when they harbor suspicion and distrust

play10:25

Its story and fate might be rewritten

play10:28

In investing

play10:29

Too many people exaggerate the power of rationality and facts

play10:32

Underestimated the importance of narrative and emotion

play10:36

So I personally think

play10:37

The result of this vote

play10:38

It is a very important signal

play10:40

Even if it is short-term

play10:42

Even if it appears on the surface

play10:43

It has no direct relation to the so-called fundamentals

play10:46

Even looking back now

play10:47

The previous worries seem unnecessary

play10:50

So you see, investing in individual stocks is like this

play10:52

You think you are making a long-term investment

play10:53

You think you can be very chill

play10:55

Don't worry about short-term confidence and performance

play10:57

But reality will always

play10:59

Drag you into a vortex of overwhelming noise

play11:02

Forcing you to distinguish

play11:03

Which signals are the ones you really want

play11:05

If we talk about investing in index funds

play11:07

Put the eggs in different baskets

play11:10

Investing in individual stocks is like Carnegie said

play11:12

Put the eggs in the same basket

play11:14

Then watch this basket carefully

play11:15

Want to watch this basket carefully

play11:17

You have to face more noise

play11:19

Please note

play11:20

What we have always been saying is

play11:22

From the perspective of long-term investors

play11:23

If you are a short-term investor

play11:24

I can hardly imagine

play11:25

The amount of information you have to face every day and every hour

play11:27

And the difficulty of distinguishing information

play11:30

In terms of signal-to-noise ratio

play11:31

A short-term investor investing in individual stocks

play11:34

It can simply be described as "hell mode"

play11:37

Your chances of winning are even lower

play11:38

As for the signal-to-noise ratio in investments

play11:40

Our Tesla in the first half of 2024

play11:42

The last lesson it taught us is

play11:44

Signals and noise in investing have context

play11:47

context

play11:48

different investment targets

play11:49

different investment cycles

play11:51

Different market environments

play11:52

Even different investors

play11:53

The signals and noise they face will be different

play11:55

The signal you think is accurate

play11:57

For others

play11:57

It may be insignificant noise

play11:59

Vice versa

play12:00

As an investor

play12:01

What you need to do is not to argue

play12:03

Is someone else's noise your signal?

play12:05

but according to their own context

play12:07

to choose and define their own set of signals

play12:09

to achieve logical consistency

play12:11

Never easily take someone else's signal

play12:13

as your own

play12:14

The video starts by saying

play12:15

I have decided to stop buying Tesla stock

play12:17

Now I will use this to explain

play12:20

The concept of investment signals and noise in context

play12:23

But before we continue

play12:24

Please give me 30 seconds

play12:25

To thank the long-term partners of the channel

play12:27

Interactive Brokers

play12:28

Since 2022

play12:29

I have transfered all my Tesla stocks

play12:31

And my US stock index Funds to IB

play12:33

The reason is very simple

play12:34

I buy US stocks in Canada

play12:36

Need to have currency exchange conversion

play12:38

Compared to local Canadian brokers

play12:39

With fees as high as 1.5%

play12:41

IB's currency exchange fees are incredibly low

play12:44

Moreover, its currency exchange is very convenient

play12:46

Besides being good for currency exchange

play12:48

IB has no fees in many regions

play12:49

Or the fees are so low that they have no impact

play12:52

And now IB will also

play12:54

Pay competitive interest rates for your cash balance

play12:56

This is very beneficial for investors

play12:58

Because you can put the cash there to earn interest first

play13:00

When there is a suitable investment opportunity

play13:02

You can invest immediately

play13:03

No need to waste time on depositing funds

play13:05

Highly recommend you click the link in the comment section

play13:07

Check out Interactive Brokers

play13:09

Your click will benefit me

play13:11

This can be considered as support for me

play13:13

Okay, let's get back to the video now

play13:14

Those familiar with me know

play13:16

I started investing in Tesla at the end of 2018

play13:18

Continuously buying

play13:19

Doubled my purchases during the pandemic

play13:21

May 2020

play13:22

Elon Musk tweeted

play13:23

that Tesla's stock price was too high

play13:25

The price at that time was around 760

play13:27

Equivalent to after two splits

play13:29

Now it's around 50 dollars per share

play13:31

After he posted this tweet

play13:32

the stock price dropped nearly 10%

play13:34

That was my last purchase for a while

play13:36

At the end of 2020

play13:38

After Tesla entered the S&P 500

play13:39

I sold a small portion

play13:40

Then I never added more positions

play13:42

My Tesla average price has always stayed at

play13:44

Around 40 dollars per share

play13:46

Two years later

play13:47

Starting from early 2022

play13:48

When Tesla dropped to over 200

play13:51

I started gradually increasing my Tesla holdings again

play13:53

I know looking back now

play13:55

The price was still very high at that time

play13:56

I can be said to be a typical knife catcher

play13:59

Left-side trading

play14:00

But I am very clear

play14:01

I can't really catch the bottom

play14:03

and never tried to do so

play14:04

The reason I started to increase my position at that time

play14:06

Because I received

play14:07

A signal I defined myself

play14:09

Regular viewers all know

play14:10

I exchanged the Tesla stock I sold

play14:12

for a vacation rental

play14:13

The main reason for selling some TSLA

play14:14

To diversify risk

play14:16

So when I did this operation

play14:18

I set a rule for myself

play14:19

I want to invest all the rental income from this guesthouse

play14:21

into Tesla stocks

play14:22

all of it

play14:24

Because I have long been optimistic about this company

play14:27

In 2022

play14:28

My homestay went through

play14:29

The most difficult period of the pandemic

play14:30

Started making stable money

play14:32

This is the signal for me to increase my position in Tesla again

play14:34

Of course, you can't deny

play14:36

At that time, Tesla's stock price started to fall

play14:37

It was also one of the reasons that prompted me to increase my position

play14:40

At the beginning of 2022

play14:41

I made a program

play14:42

Shared my plan to increase positions

play14:44

I said I will continue to buy Tesla

play14:46

and index funds

play14:47

As for Tesla

play14:48

My goal is to keep my overall average price

play14:50

below $200 at that time

play14:52

which is now $66 per share

play14:54

From 2022 to now

play14:56

I have been buying continuously

play14:57

Bought the most this year

play14:59

The last purchase was on June 11th

play15:01

Two days before the shareholders' meeting vote

play15:03

Then decided to stop increasing positions for a long time

play15:05

The reason is my average price

play15:06

It has reached $65 per share

play15:08

My stop-buy signal has appeared

play15:11

You might be curious

play15:12

Why do I need to set such a goal

play15:14

This actually involves investment signals

play15:16

And the concept of noise context

play15:18

I set this goal

play15:20

with many very personal considerations

play15:22

including the margin of safety I want

play15:23

Position ratio

play15:24

Risk control

play15:25

Psychological endurance

play15:26

Allocation of overall family assets

play15:27

Even tax considerations and personal age

play15:29

As well as many details such as health

play15:31

These contexts are very personal

play15:33

So you can't take my goals

play15:35

Average price and investment ratio

play15:37

As a signal for your investment decisions

play15:39

This reminds me of what happened to the interviewee

play15:41

Former Tesla FSD engineer Lao Yu

play15:44

The interview I did with him

play15:46

Was very successful

play15:47

After the interview

play15:48

Many people have started to question Lao Yu

play15:50

Some people say you are so optimistic about Tesla

play15:52

They think it can be 10 times better

play15:53

Why don't you increase your position in Tesla

play15:55

And why not go all in on Tesla

play15:58

Only let him take 10% of your assets

play16:00

Some people even say

play16:02

He still doesn't understand Tesla enough

play16:04

Or he is just fooling others

play16:06

You see, this is a typical case of neglect

play16:09

Context in the signal-to-noise ratio of investment

play16:11

They assume Lao Yu

play16:13

Or that I am watching with them

play16:15

The same set of investment signals

play16:16

Assuming our personal situation is the same as theirs

play16:19

This is obviously a misjudgment

play16:20

The reason investment is complex

play16:22

Because it is mixed with countless contexts

play16:25

Someone who started investing in Tesla in 2012

play16:27

And from 2016 to 2018

play16:29

People who started investing in 2021 and 2024

play16:31

Face different contexts

play16:33

A young person who has just entered the workplace

play16:35

And someone who is about to retire

play16:36

Facing different health challenges

play16:38

A stable and high-income earner

play16:40

With an emotional fluctuation

play16:42

...

play16:43

Is completely different again

play16:44

Now, back to my investments

play16:46

For a long time in the future

play16:47

I probably won't continue to increase my position in Tesla

play16:49

Only hold for the long term

play16:50

Then my funds will mainly be invested in

play16:52

Index funds and my own business

play16:55

...

play16:57

So, is there a possibility that I will increase my position in Tesla in the future?

play17:00

I don't know yet

play17:01

It depends on my context

play17:03

So after watching this video

play17:05

You shouldn't base your investment decisions on mine

play17:07

...

play17:09

You can only fully understand yourself

play17:11

According to your own context

play17:13

Define signal and noise

play17:15

Because many times

play17:16

Although we are all investing in the same target

play17:19

But we might be in two completely different worlds

play17:22

OK

play17:23
