There was an interesting Inverse Head and Shoulders pattern completed last night on SPY. As SPY is the proxy ETF for the S&P500 index, it caught my attention. A closer look at the Chart attached shows this pattern usually breaks out to the upside.

Analysis of the supplementary information clearly shows that the uniformity of this inverse head and shoulders is good, however the overall quality of the pattern is only average. The biggest issue is the lack of volume and lack of power of the breakout. The volume is particularly low. More volume is needed before this pattern is confirmed, particularly on a strong up day.
