Retail Buys into market at these levels

For ease of viewing...I created the S&P 500 price history on the chart colored Red for retail outflows of significance and green for inflows. Retail participants sold essentially the whole move up and it looks like between rotation out of Muni's and general CNBS/Wallstreet and Press market pumping has piqued their interest again - just as it had before the "Fat Finger Flash Crash". Now that the general public seems to be paying attention...is the train already leaving the station or is it actually of consquence?
