Looking at the larger swings;

Since 2009 lows, XGD is up 110%, SLR is up 2,100%.
Since 2011 highs, XGD is down 38%, SLR is down 25%.
Since 2012 lows, XGD is up 8% and SLR is up 45%.

Both are very volatile and both have been sold down heavily near term.
Next move when it starts should see a strong rise.
Both are near their trend lines.
The next up swing may be from the trend line, or maybe from around here.

SLR has dropped by more from late 2012 highs but only because it gained 100% to record highs prior to that correction compared to a much smaller gain for XGD (not even close to reaching 2011 highs) so talking about underperformance since that correction began is not looking at the overall picture.
