ARTC was a pre -market gapper with momentum after announcing they were restating financial statements. This kind of news is deadly, so you want to get in as soon as reasonably possible. Markets don't like the unknown and restatements inevitably lead to write-offs or write-downs. A great example is NT which restated at least ten times over the past seven years. Still not sure these guys ever got it right. My second attempt to get in was not in the cards as the stock became unavailable for shorting. No surprise there. As I mentioned in pre -market, I was expecting some backing and filling after last week's big thrust. LEH played into that scenario perfectly. After taking out resistance in early trade, it couldn't sustain the higher prices. It carved out an IB at support which closed on its lows, setting up an easy short back to the next level of support.
