I don't know what I was doing in 2012. I remember I had to have any stock trades precleared before I can do trades. It was too much hassle, so I just didn't get into any investment on stocks back then, other than BIDU which I already had when I joined the company.
As for META, I bought it early this year around 400, saw it had several times of about 20% drop this year. Sold @520 to add some NVDA. Earnings season is tricky, it could go either way for big movements. I am afraid it will rise 20% after earnings this time. So I want to get in before that happens. I have a price target of 760-780 in 2025.
