The volume was a HUGE 28.37M shares. Total volume for the first 5 trading days after the judge's rulings on 2/7 was about 91M shares! BTW, the closing price on the day that $2.77 was reached was $1.70. So SHLDQ closed almost 40% below its high.
This is all hindsight of course, but the best days to take your profits would have been from 2/12 to 2/14. The highs those 3 days were $2.10, $2.77, and $1.99.
