Tesla’s stock price fell tremendously yesterday.

Tesla’s stock price fell tremendously yesterday.

Media, Investors Worked Hard to Find Why It Fell.

Most people said, “This is because certain media reported that the robotaxi announcement was delayed from August.”

By the way… Isn’t that a little weird?

Tesla and Elon Musk have pushed back on existing announcements or plans more than once, but they have not plummeted like this each time.

I know exactly the reason for yesterday’s crash. This is not what I said. A distinguished scholar has said, and there are many past history.

That’s because it went up a lot. This is called “Regression to the mean” in statistical terms.

This is one of several “cognitive delusions” mentioned by Daniel Kahneman, the first psychologist to receive the Nobel Prize in economics.

Even the psychology students they teach emphasized that they do not accept this average regression as ‘psychological’.

The U.S. stock market has gone up a lot lately. No matter how long-term the U.S. market is on the right, the recent uptrend has been steep. So, in yesterday’s market, most big tech stocks have gone down.

The media gives various reasons for CPI or interest rate, but it has only returned to its original rate of increase.

And Tesla has just fallen that much more, because it’s skyrocketed longer and more than these companies.

The only reason the media and so-called experts say is ‘just looking at the results and putting them on’.

The announcement of the postponement of the robotaxi could be a “trigger,” but that’s not the cause. It’s just that the news was ‘pinggye’ and the amount of profit realized was poured out. Even if there was other news, it would have fallen under the pretext of that.

So you don’t have to snoop around saying, “What’s the reason?” because it plunged after a sharp rise. Just think of it as, “The recent rise was fast, so you returned to the average rate of increase by falling.”

I hope this opportunity will serve as an opportunity to learn ‘average return’ properly.
