On Friday the short selling dipped below what occured on Jan 8th, (the day before the big run up). AND, over the course of 4 trades someone with money to spend purchased 90,000 shares in 4 seperate trades. Check the one day chart at 11:25am,3:15pm,3:45pm and 4:00pm. Using an average price of $4.90, these purchases come to $441,000. I would think that whoever did this knows something and was not acting randomly. ALSO, the one day chart on Friday indicate a double bottom at the price of $4.81 and later it bottomed and bounced off of $4.88 four times! I would not be at all surprised to find news being announced on Monday morning.
The RSI didn't rise very much because it is calculated to measure momentum...when it went to 5.98 but then closed at 5.26, the momentum was reduced and it was reflected in the rsi number, had it closed,say at 5.90 then we would be left with a much higher rsi.
