Crashes come when you least expect otherwise it wouldn't be a crash. The market knows about everything you just listed, the market is baking that into its calculations. The correlation between the stock market and real world fundamentals has always been qualified. A lot of investors don't care about today, only tomorrow. You can have big companies with popular products, but if the market doesn't think it's going to grow then the market isn't going to pay much attention.
