Retail Investors Getting In The Game

Higher stock prices are leading to higher inflows leading to higher stock prices. From Reuters: 

Investors put a net $9.45 billion into equity funds, the best performance since the week ended June 16, the data showed. That was a near four-fold increase over the prior week's inflows of $2.54 billion.

According to SentimenTrader.com the current level of mutual fund inflows has been matched only once since 2002. It was followed by a sideways to slightly down period for a few months.
