FYI: U.S. markets essentially made no gains in 2015. The major indexes are more or less flat for the year to date. The Nasdaq-100 Index has done best, gaining about 8 percent, driven by a handful of big winners such as Amazon, which is up 116 percent for the year. Yet the flat returns belie a big increase in volatility, including a sell-off of almost 20 percent at the end of the summer that investors had made up by late fall.
