"It could mean one of two things....1) There's someone dumping shares into the LSR and other bullish news, but they don't want to reveal the house they're using. 2) There's someone shorting who likewise doesn't want to reveal what broker they're employing."

Someone? C'mon, you know there's no evidence for that.

"Anonymous" isn't selling. Shares are being sold anonymously. It could be one person or 20.

Holding onto conspiracy theories to explain drops in the stock or why it doesn't go up is a bad idea.

Do people sometimes play games with stocks? Sure. (Yes, yes, I know short interest goes up and down.)

But the vast majority of the time there are reasonable and rational reasons for the stock to be where it is.

Looking objectively and dispassionately at those reasons will serve you better.
