Dump The Pump

[satelliteguy]

That's a good post by that guy about the "short volume." Here was my simplistic variation, as posted on a couple of boards:

"Market makers don't generally maintain inventory, so typically, they sell short and then go high bid to cover. They generally try to end each day flat. Most or all of those reported short sales were undoubtedly covered the same day. With a stock that is stable or mostly dropping, as NXTH has been, MMs will have had no difficulty covering their short sales for a profit.

When an MM buys first and sells later, neither side of that trade will be reported to FINRA. But this is relatively uncommon.

This obviously doesn't apply to those situations when an MM represents a buy or sell order from a customer."

and

"Market makers generally sell stock short and then go high bid to cover. Therefore, the reported short volume for a given day for LHRP should be about half the total volume (short 100,000 first, which gets reported, and then buy back 100,000 which does not get reported)."
