The problem is that the stock market is moving in an increasingly greater-fool direction. Companies that don't ever pay dividends, companies that don't yield control rights, companies that have extensive protections for the founders, etc.

The problem with the stock market is not that its hard to tell whether you should be in or out. Its that there's so much pressure on the general population to own stock that the stock issuers can now get away with releasing essentially worthless stock (see Snapchat for an example) and still expect it to sell anyway.
