Zynga stock has gone down so much in the last 4 days, that any good news makes it ripe for a big increase. With them, any good news normally happens after hours. So, my new technique with this stock which I started today, is to buy it on the close and sell in on the open. As long as it's not still going up. Most cases, I should be able to sell it at the open for about the same as I bought it. Sometimes more, sometimes less.
