Nobody knows for sure. However, as the S&P, Dow and Nasdaq100 have been in modest uptrends, my bias is to the long side. So, if all these indices go up I would like to be long, and if they don't all go up or if some or all go down, I will remain in cash.
A better chart to the down-side, inversely correlated to the stock markets, would be Gold: I would be happy to be short Gold instead of long the indices.
