Housing starts surged 13.2% in April after the long harsh winter. But, the better than expected report is not enough to overcome the selling the market is seeing from overseas investors, says Ben Willis of Princeton Securities. Willis says options expiration is also making it a rocky start to the trading day. Willis, who is bullish on energy stocks is not concerned that the group is down on news from Chesapeake. Willis believes the economy is getting stronger and that this group will benefit. Willis says that any selloff should be be seen as an opportunity by investors to buy stocks.
