I've got over a decade of experience as an accredited investor. The groundless insult with no other content to go with it is inappropriate for Hacker News and blatantly violates the site's rules. What made you so upset that you felt you needed to lash out toward a stranger on a forum?
If you want the straight-forward argument: FB is an easy value play on the reaction. Assume a continued slowdown in growth, by just the end of fiscal 2020 they're at $35 billion in profit against an AH $500b market cap = 14 forward PE ratio. You have to be willing to bet on persistent multiple compression across years, I'm going to bet the stock goes up and maintains a reasonable multiple based on their growth rate being beyond that of their peers. One of the best value plays in tech on multiple vs growth rate.
Match their multiple to Microsoft and Google, even despite having faster growth than both. Instead of a $500b market cap, in a little over two years they're at more like $900b-$1t. Or play it more conservatively, assume a fat discount vs Microsoft and Google, a 20-23 type PE ratio, then they're at a $700b-$800b market cap. That's a 40%-60% return in 30 months, on a conservative scenario.
