There is an old adage about when the VIX is too low. During the past 5 days, it dropped almost 40% and it is now at a historically low level.
Since the VIX (Volatility Index) moves opposite to the stock market, it is saying: don't worry, everything is wonderful.
This hard to believe message is scaring some very large Institutional Investors because historically, a VIX this low doesn't stay that long. Enjoy it while it is here.
