Yes, the short interest is now 145k shares. That's about 2 hours trading on an average day. Of course it's way up, it covers the time the stock doubled to 44 cents a share. That's when people short stocks like this, after a big run. Still it's only about $60k worth of short sales and now would cost about $30k to cover.
Many stocks see spikes in short sales when the price jumps on hype. Then when it falls again, the short sales fall also. Take a look at the history of EIGH's short positions and you'll see what I mean.
Hard to get a short squeeze with 1/10th of a percent short.
