March 20 (Bloomberg) -- The U.S. stock market is the most volatile in 70 years, according to a Standard & Poor's study of daily price swings in the S&P 500.
The benchmark for American equities has advanced or declined 1 percent or more on 28 days this year. That's 52 percent of the trading sessions so far, which is the highest proportion since 1938, said Howard Silverblatt, S&P's senior index analyst. The S&P 500 lost 12 percent in 2008 through yesterday following $195 billion in bank losses related to subprime mortgages.
I didn't need S&P to tell me that; this market has been absolutely emotionally exhausting since last August. I needed today off to recharge. Hopefully things will calm down soon, but I'm not counting on it.
