$Berkshire Hathaway B(BRK.B.US) won't enter the market unless the daily chart is oversold! When will I strictly respect my market indicator signals, when will I strictly follow discipline? Paid tuition again, the feeling of being pinned down and tortured🫥

In the final analysis, I think it's still greed in thinking and severely inadequate execution;

However, I really haven't understood this BRK.B recently. It's said to be a defensive stock, but why does it fall when the broader market falls; it also falls when tech stocks fall; it still falls when tech stocks rebound. In short, it's been oscillating downwards and falling all the time. I just don't get it;

Also, sometimes there are sharp rallies or drops in the pre-market/after-hours/night market, but it still shows a decline during the regular session. Sometimes it feels even more sneaky than tech stocks;

Regarding the understanding of price movements, sharp drops and rallies, and market waves, I think I'm still more familiar with SOXL and CRWV. At least they follow the market (soxl follows semiconductors, crwv follows NVIDIA). When there's good news, they rise as they should; when there's bad news, they drop sharply as they should; when there's a reversal, they reverse as they should. (A personal summary of some recent puzzling operations. Making mistakes isn't scary; what's scary is not knowing where you went wrong. Learn the lesson, improve, and hope to get my rhythm back.)
