RE: Retest of short term lows.. Obviously not a good day for PSN. However, to put it in context the TSE is down pretty well 400 points in two days and if you compare PSN to the other Oil service companies it is holding up about the same.
Also todays selling is on quite low volume, which shows that investors are not running to the exits but there is a shortage of people willing to put more money to work in this market environment.
Oil dropping over $4 obviously is not helping the oil or oil service stocks, but is good for the US and World economies overall.
PSN will continue to pay its dividend, continue to grow its business, its earnings, and therefore eventually its share price.
