I can't believe someone would short 28K shares of an illiquid stock. Very risky. I can understand shorting when OMAG doubles on huge volume, but not when volume is light. (Did anyone see the massive short sqeeze in KBIO last week? The stock was under $2 on Wednesday and traded over $20 on Friday!)
I was watching the trading of OMAG on Friday and there was a block of stock for sale. I think nearly 30K shares. Buyers kept picking away at the block. I hope the buyers know more than the seller/shorter.
