A predominance of odd-lot trading, yesterday. Lots of small trades in narrow swings. Tells me two things: retail investors are beginning to move into positions, here, and HFT traders have discovered a pattern to the swings and are starting to play in our sandbox.
That's all good stuff, although it is likely to inject some volatility into day-to-day trading's impact on S/P.
