On Feb 2nd, I moved 85% of my 401k to cash.

No need to try to be a hero towards the end of an 8-year non-stop bull run. The market appeared it might be stalling and the 600 point drop was enough for me to head to the sidelines. Of course, it was only down around 200 when I placed the order, but with mutual funds we are stuck with the closing price. Thus far, my mass transfer into cash seems to have been a great move as the DJIA has dropped another 1,600 points over the past week. Another 4,000 point drop to sub 20,000 on the Dow would not surprise me at this point. See my REAL-TIME ALERT from 02.05.18.  Plunge Protection Team might get a workout soon.
