There have been some comments about the low volume. There is a saying that volume is the fuel of a bull market, which makes sense intuitively. However, I have never been able to make any market trading decisions based on volume.
Volume has been of some help in individual stocks. When a stock is plunging on heavy volume and I want to try and pick a bottom, I look for a slowdown in the volume. A short term bottom usually comes shortly after the slowdown in volume.
