Outside the Box

EVERYONE CANNOT BE RIGHT

In other words, the entire value of the financial sector (not just banks) in the S&P 500 is around just 15%. If all banks went to zero tomorrow, the index would only fall 15% further ...
There are some prominent economists who believe that equity stakes in large banks are ... valuable. The market, interpreted one way, is saying something else, perhaps.

The VIX, the volatility measure on the S&P500 broad stock index, is around 55%, today. That says that the standard deviation of the S&P500 is 55%, annualized. Assuming a distribution, you reasonably interpret that to mean that the S&P could drop 55%, without 'extraordinary' circumstances.

Now, I'll tell you, that price is so high, it is higher than if the value of all the equity of all the banks in the index was worth nothing. In other words, the entire value of the financial sector (not just banks) in the S&P 500 is just 15%. If all banks went to zero tomorrow, the index would only fall 15% further ... that's way less than 55%, right? Both cannot be right.

What to do?
