I'm relieved to see the price drop to $0.0001. I removed the 'All or None' restriction from my buy order for 140K shares at $0.0002, just to get as many shares as I can, even if it's <140K. I run the risk of sub-lot fills, but Schwab won't let me use their "Minimum Quantity" feature.
I think Humanigen will declare a 5:1 forward split in part to buyout IPIX, and since I can't buy anymore HGEN shares, I'm trying to add to my ~4 year old position here.
