There has been a lot of option activity lately, and today, a whole lot of warrant activity, too. Also, some pretty determined/heavy selling the last two or so hours in the common stock, which has me a bit concerned for Monday.

The long option prices are good, Lia seems to be doing a great job of trading them. But selling some against stock holdings is not a bad way to reduce some risk, and perhaps not jeopardize your upside meaningfully.

To explain the open interest on some option positions decreasing, it's possible that some people decided to sell their call options and buy warrants in stead. Hard to say what all has been going on, but this little stock has been a cauldron of activity last couple of months.
