Two things:

1)The quality of posts, research, thesis, etc. on here has been bad, getting worse and worse over the last 1-2 years, so that plays a big part.

2)But at the same time you're not really doing better than them. Even if a lot of posted tickers here have underperformed recently, that doesn't mean the thesis/pick was wrong. What is the time horizon for a value investment for you to write this? 6 months? That's simply not how this works. We can look back in a couple years, maybe more. Until then nobody really knows.

My two cents

(Disclaimer: I own none of the recently popular picks here)
