Means tax loss harvesting time - dump between now and say 8/20 and then buyback between 9/20 - 9/27 to take losses and avoid wash sale(s)!
Sure hope Mc doesn't announce a fund raise in 10 days to 2 weeks from now or it could get ugly. Wonder if THAT will be a clear sign of loyalty that Martha may demand ? Its definitely possible and sure would keep PPS down.
Note: 9/28 is the EARLIEST that the $11M milestone payment hits
