Best Buy for IQbuds, page-31

The only thing that can be said with reasonable certainty is that whoever it is does not pay $19.95 per trade. It doesn't make sense were that the case. So that rules out retail, pretty much.
Would they be a long term holder? No, I don't think so. I don't think they would be interested in NUH or anything else as a long term hold*, say a month or longer. For them, it's purely trading.
If I am right in my explanation, that the 'one share serial seller' is in reality much more a buyer, then that party's expectation is that NUH will go up within the time frame of their main trade. Otherwise, they would not be buying. You don't buy to sell for lower.
There may be another plausible explanation for why these one share trades have been around near the close for the last week or more. If so I'd like to hear it.
* That's not my definition of 'long term hold', just trying to explain it.
