Overnight Weekend Hold??

So I have been looking at this stock. It has been on the rise. I am not a long term holder normally, but this has the opportunity for a overnight weekend hold. The pattern has been like this all week. Normally this stock rises during pre-market, and it is dumped once the market opens, then bought again before the market closes, then dumped again. I am betting that it happens again today. I am going to buy if it hits my support area. I will hold , then dump (following the pattern). Rinse and repeat?......I don't know, but I am all in.
