Makes sense in some situations, but not in this environment. Unemployment up, projections for growth down, cuts in government spending adding to a slowdown, and no solution to the Europe problem. This is 2008 all over; i.e. remember the Fed cutting rates because of the threat of a crisis....don't fight the Fed and buy stocks was the call of the day. That didn't pan out too well. Buying a retail ETF today because oil is going down in today's environment is a bad call.
