I second what Mister Ed says about taking profits near the previous highs. I think this stock has more interest to the down to sideways side than to the immediate upside at this juncture. Here is a weekly chart of STX alongside a daily chart of it's main competitor Western Digital. I also included a sector snapshot to visually display that that this isn't the most active sector in the market as of right now.
This was a nice swing trade if purchased near the swing lows...
P.S I'm surprised no one has mentioned the possibility that the large orders could have been short covering by a large entity as well...
