In this daily chart of ALLY, above, we compare the movement of the XLF to ALLY. The thin line chart is the XLF and the daily bar chart is the movement of ALLY. Notice how the XLF has outperformed relatively on the upside since late October? Trends in relative strength tend to persist as fund managers and other investors look to buy the outperforming stocks and not the ones that underperform. You cannot buy laggards if you want to beat your benchmark.
In this one-year daily chart, above, we can see how ALLY has stalled several times in the past three months at the $20 level. The 50-day moving average line is flat and the 200-day average has only been on a positive trend since early October. The On-Balance-Volume line has stalled right along with the price action while the MACD oscillator has narrowed toward a new sell signal.
This three-year weekly chart of ALLY is interesting in that while ALLY is above the rising 40-week moving average line, it seems to lack buying enthusiasm. The OBV line on this timeframe has been going sideways the past three months and the Moving Average Convergence Divergence (MACD) oscillator has been "waffling."
Bottom line: ALLY's weak price performance vs. its peers is likely to continue.
