This has been a good week for solar. Solarcity (SCTY) extended its bounce off a key support, and First Solar (FSLR) rebounded despite breaking a key support. However, FSLR might see some resistance as it attacks the 40.00 handle.FSLR Daily Chart 9/29(click to enlarge)Resistance cluster at 40:- First let's acknowledge that FSLR has been bearish since March falling from about 74.30 to about 33.75 last week before the bounce.- The overall mode is still bearish.- As price moves to 40, it meets a falling trendline seen in the daily chart above.- Note that 40 was also a previous support pivot.- Price also meets the 50-day simple moving average (SMA).- Furthermore, the RSI is here around 60, where it should hold if the momentum is still bearish.Non-meaningful retreat vs. bearish continuation:- A non-meaningful retreat means one that does not matter if the overall trend is bearish or bullish. It would just be a reaction to the 40.00 handle.- We can probably expect something like a 5-8% dip to 36.75-37.50 area, which was a common price for FSLR in August.- A break below 36.60 would likely be part of a bearish continuation that would have the 33.75 low in sight with risk of simply continuing the prevailing downtrend lower.Break above 40:- Now if price pushes above 40 today, we might have a breakout that can open up the 44.15-45.00 area, which involves the bottom of a previous consolidation range as well as the 100-day SMA.- The bullish reversal scenario can sure use some more clues such as a higher low, preferably using the common support in August above 36.75.
