According to Berger, there are several signs that a correction is due in the US equity markets. Trading has been choppy and the volatility seen in currency and commodity markets is likely to spread to equities, which could all lead a downside correction of as much as 10-20%, he says. 

When that time comes, Berger argues that it is far better to be holding cash and be able to make a calculated buy on the dip than to be locked into active positions. He is looking to readjust his portfolio accordingly to preempt a market move.
