The media is not trustworthy

Regarding the stock market, it is best not to rely on the media.

After the morning close, the TV reports that interpret the stock market will announce the ranking of trading volume every hour. For example, there is a report like this: "Although the yen has risen, Toyota's trading volume has increased due to the high expectations of Toyota's performance in the United States."

At that time, I also bought a lot of stocks with high trading volume on the Tokyo Stock Exchange. Because I only trade in the morning, it is common to buy and sell billions of yen, which accounts for a large proportion of morning transactions. If you look at the whole day's trading in the stock market, my trading volume is less than 10%, but if you look at the trading around 10 o'clock in the morning, sometimes it accounts for 30%.

So the TV program talks about exchange rates and the US market, but it is just piling up some factors and then connecting them together and talking about them verbatim. And I, who accounted for 30% of the trading, didn't think about those factors at all. I just wanted to sell it tomorrow, so I bought it today.

It was obviously me who affected the stock price during that period, but the media had no idea what I was thinking, and interpreted it based on my imagination.

Here is the original text I saw in the book today, stay away from market noise
