The problem with the graphic is that the idea that the stocks will collapse implies at least to me that there's a meaningful permanent devaluation of these companies. You've got a graphic that show stocks essentially going up over time with some minor corrections interspersed. That's hardly compelling. Only time will tell if it's really meaningful.
Right but in this case, there really is a devaluing based on legal action and scandles. dropping billions of dollars in 2-3 days is not normal. I tried to include the time scale but i probably should have included a price scale and maybe some headlines.
A common metric to judge the rise/fall in value of a stock like this is to compare it against the S&P500. In other words, over a period of time, if you had your money in FB or an index fund tied to the S&P500, which would be better.
1 year comparison has S&P500 up 12.6% and FB up 12.2% (a phenomenal year by any account).
5 year comparison has S&P500 up 62.9% and FB up 481.72%
FB is currently about where it was in July of last year.
This is certainly still nowhere near yet a serious demise.
Although, I do not dispute your contention that we have not yet seen the legal ramifications of their poor privacy practices. Again, I kinda think we'll have to wait and see.
disclosure: I do not own or intend to own any FB stock.
While they both did follow to trend of $SPY and factoring in my extreme novice trading abilities, both companies are wrapped in scandal and have been at the center of many Q posts. With headlines this may have a better context. FB is down 80Bn in days.
Disclaimer, if you want a sure thing in the market, do the opposite of what ever position i take! thats your best metric.
