Is the drop the last 2 days a buyable dip or the start of a huge drop?

I would wait until there is some stability. Catching a falling knife is dangerous.

 

There is that possibility, although given your record. This prognostication is statistically bullish.

 

imho, the chart for the S&P 500 looks pretty ugly with those two big red candles form today & yesterday. 14500 for the DJIA short term target
