It is odd, companies have been sued for less.
The S&P500 is up 100% from 5 years ago. If you want a long term investment, that's way less volatile than Tesla or Nvidia
As for stock pickers holding positions, well a lot of people do. As they should.
Being "at october levels" still wouldn't be a good way to judge baseline. We would expect a decent stock to at least keep up with the gains of the S&P500 or some other representative index
For long term holdings volatility doesn't matter much - I'm generally happy to take more volatility in exchange for higher expected returns. (Or else, I wouldn't be in stocks at all, I'd be in GICs and treasury bonds.)
(That all said, I'm not long on Tesla; I have individual short positions to roughly neutral out my Tesla holdings within ETFs I hold.)
