History always repeats, but when free money just comes pouring in and every day stocks push higher even during the biggest crisis in history and you have the fed backing the stock market you think at these moments that its nearly impossible to sell off to new lows set in march let alone the s&p falling below 3000 now.
The euphoria is already here and not going anywhere even if the markets were to drop say 7% because everyone would be screaming a buying opportunity of a lifetime especially the masses of new investors since earlier this year and those who missed out looking to get in. The cycles always repeat but when you have a fed that doesn't allow free markets these markets tend to lean in one direction far longer than anyone's imagination ...like i mentioned it seems markets can never ever be overvalued even after a fed backed 10+ year bull market but can quickly become oversold within just days....
