Actually I just checked and Sykes went long REFR at $4.00 per share.
Just Google "Timothy Sykes REFR" and you can see his video on REFR. On the site he said in April he bought at $4 and expected a big run up to $5 even $6 or $7 in 2-3 months. It did not do that but he was looking at the chart. If he did turn around and short REFR in July as is posted here, then he is also down quite a considerable %.
I doubt though that he would short a stock on such small volume. If he did, then perhaps he's the reason for the run yesterday?
I don't think so. Just new interest and no sellers. Big chunks of shares offered for sale have just been grabbed up. Yesterday, it was 9,000 in the mid 4.30s and again and today 6,000 at 4.53. Now those shares are most likely shorts because anyone who wants to get their sale price aren't going to advertise twice the days volume for sale.
The buying isn't covering. Would be stupid to run up the price on a no news, low volume week Just some interested buyers.
