That is insane!!
There have GO TO BE easier ways to make money than to short IDCC!
I know most are probably legacy shorts! There were about 250,000 new shorts added that week when we corrected from the high 90s to the low 90s. I gotta believe that was the legacy shorts doubling down trying to get a decline going to erase some of their losses. In reality they have just dug themselves a deeper grave, unless there is a market crash or some terrible unexpected news.
If they have enough margin, they can stay short forever i guess, but they have to pay dividends and interest!
