Ann: Annual Report to shareholders, page-47

That is such a flawed argument
The market goes up and down no matter what stock it is.
If your in short term , then yes it would have been a stroke of genius to get out higher and you would have been Nostradamus to pick such a drop in price.
If you’re long term and still believe in the company , you can view this as a minor glitch. Just like I’m sure the shareholders of VUL, CHN, FMG etc etc did when it looked like they were going to do their ass. It’s about what you want out of your investment.

So please stop with the hindsight crap.
If you’re long then stay the course unless of course you’ve lost all confidence in which case , sell.

Horses for courses. There is no right or wrong answer. It all depends on your circumstances and your belief in your investment.

I had a million Dogecoin a few years back. Sold it for a few cents and made decent money. We all know where that went to when Elon Musk jumped on board. I can cite many of these examples in both shares and Crypto.
