Should AMPE close above 6.50 and it will., Stock will go much higher. Most brokerage houses raised the margin interest rate on shorting this stock to 33.25%! That's almost 3% per month to short a stock that can rise with no limit and fall $6. There are 5.1 million shares short that are paying this amount???? I remain short on REGN/ LONG AMPE/ LONG TSLA, LONG NFLX, SHORT GOOG and now SHORT ON the DOW.
