The Guggenheim Solar ETF (TAN) has recently been in a sharp decline, from roughly 33 to 22, losing 33% in a month. TAN 4H Chart 1/27(click to enlarge) By mid-January, price has broken a consolidation range support and tagged a previous resistance pivot around 21.50 (you can see that pivot in the weekly chart below).Immediate Resistance: Now, as price bounces off the 21.50 pivot, TAN is approaching the previous support area around 25.50, which is also at about the 38.2% fibonacci retracement. This resistance area is reinforced by a falling speedline just above it. Critical Resistance:Then, around 28.60-29, we pretty much have the last line of defense. In the 4H chart, a break above 28.60 pushes price above the cluster of 200-, 100-, and 50-period SMAs, which shouldn't happen in a downtrend. A break above the 61.8% fibonacci retracement level is also an unlikely event if the market were in a downtrend.
