You must have sold around $4.20-$4.30 last Friday as per your postings. You had a good chance to buy it back yesterday in the $4.35-$4.55 range easily. With your 20k shares, you would have ended up buying it back for about $6k more than you paid for it. It's not such a big deal. What if RDN goes up to $5? That would be another $6k or so. More importantly, people will jump on it when it touches $5 sending it higher. What's your solution or will you just complain if it goes higher?
