First Solar up 17%: the signal holds, the next test is the week-8 window

First Solar is at week 6 of a buy signal initiated in the 220 area, with 17% in gains already locked in and the first model target hit at week 5. Signal strength stands at 81 out of 100, but the profile is wide-range and volatile: the setup quality index sits at 62 out of 100, in an ordinary phase. The stop has been moved to breakeven — trade risk is zeroed out.
