This is what I did, and it's an example, not advice, with a ST/DT parcel.
My buy was at $3.45 for today's trade. (I also hold a MSB long from some months ago.)
Sold half at $4.95 this morning. Will sell the rest after 3pm today. If it's above $5 then, I might be tempted to hold a small amount over the weekend, to take advantage of the NASDAQ trading and make a gap up gain Monday.
Given the media attention this will receive it may never pull back. I am likely to buy again for short term hold last week of Sep. This is a capital gain method of trading and his tax implications.
