As we know the stock market is pretty overbought especially such the giants like Amazon, Facebook and so on.
Ugh...I wouldn't touch either one of those stocks. None of the other tech and social media stocks, either, like Twitter and so on. That stuff smells too much like 1999 to me, even though some of them are actually making money (like FB).
History would tell us that the stock market is due for a correction, and even though I tend not to look at history in order to predict the future I'd tend to agree with that. Eventually investors either get scared or start taking their profits out of the market, and I'd agree that right now the stock market is certainly inflated to the point where stocks are on average very expensive.
I doubt Warren Buffett is buying many stocks in this market. You would have made an absolute killing had you bought in in 2009-2012, but right now you might be buying at the top, just like bitcoin at $20,000. But we'll see. I haven't heard any really bad news that would suggest that the stock market might be in for a crash instead of a correction, but you never know.
Stocks are in a bad place, so I have been told. People are really trying to weasel out of it, and not make a big loss. FB is no longer making as much money as you may think it does. It recently got hacked again and 50 Million user's data is potentially and alledgedly leaked. FB's privacy and security is a joke and that's leading them nowhere. Other stocks aren't in a great place either, if I wasn't clear earlier. They may look as if they are doing good, but in reality things are really much different.
