GulfMark Offshore Inc. NEW (fka GLFMQ) (GLF)

[THREE-DAY-TRADER]

As I posted about earlier here, there was a re-balancing of an index that sold GLF, and recently it bounced from that point after the re-balance sell off. Just technicals mainly affecting it; short term supply/demand of shares caused an excess to the downside, and a following move up because it was oversold.
A pop after an excess of selling is perfectly normal.
