Israel rolled into Lebanon yesterday. You didn't think there would be a military response to an attack on a sovereign nation?
Personally, I didn't make $$ on NVDA today. However, I bought oil stock in after hours trading last night. That was the sure bet, safe play for today.
If you follow the news and learn how it impacts the markets, there is a lot of $$ to be made. Sticking with one stock, with all of the volatility and turmoil, truly limits one's ability to profit.
Good luck to you.
