I know there will definitely be someone telling you that if you are optimistic about a stock, you must hold it firmly, even if it gets cut in half, the future will surely satisfy you!
This foolish method is nothing but a stubborn refusal to admit mistakes. When the market rotates and you hold a weak stock, that leads to huge losses.
Slowly understand that in a bull market, even junk can rise tenfold; it's just fools deceiving themselves! Be alert and don’t listen to those who tell you to hold on single-mindedly, as you may end up missing an entire market.
