The S&P 500 is up 0.5 percent and the Dow is down 0.5 percent since the start of 2018, but the Russell 2000 has risen 2.3 percent. Furthermore, the... more

We've suspected for a while now that investors weren't really as bullish as the quick look at the chart would suggest. Mostly, they're indecisive, not really sure what to expect.
