The stock market rout is starting to get really expensive – destroying $2.3 trillion from the market’s top last year and $1.5 trillion in net wealth just this year. The giant companies that predominantly populate the Standard & Poor’s 500 have fallen an average of 9.2% this year — which when translated into dollars — is real money. Real big money. The S&P 500 is down 8.1% this year already — including another 2.3% Friday — in what’s been one of the worst starts to a year ever. Since the market peak on May 21, 2015, the market has declined 11.9%.
