The HAL / BHI deal probably put a temporary low in the OIH.
$FSLR and other energy derivatives have sold off hard with the recent decline in oil and the energy space.
$45.80 - $46.25 looks like a decent level to get long for a trade. At least cover shorts there.
RSI shows an oversold condition as well.
Target is the 9 dma (currently $51.77 but declining).
