Stocks are pointed lower Monday morning, amid falling commodities prices, renewed concerns about Greece, and uncertainty about the true impact of the passage of the health-care reform bill. Thirty minutes before the opening bell on Wall Street, stock index futures indicate that the Dow Jones Industrial Average might lose 40 or 50 points at the open.

Stock index futures traded lower after the House passed Obama’s health-care bill Sunday. While the win moves the bill one stop closer to reality, no Republicans have supported the reform thus far and there is uncertainty about potential delays and amendments in the Senate.

Meanwhile, markets are broadly lower across the Euro-zone after German Chancellor Angela Merkel said in an interview not to expect a Greek aid package when European leaders gather at a summit this week. A 1 percent loss in France’s CAC 40 Index is pacing the decline.

Crude oil fell $1.31 to $79.37 a barrel and gold shed $3.1 to $1104.50 an ounce.

With no economic data to guide the morning action, bonds are flat in quiet trading. The benchmark ten-year Treasury is unchanged and still yields 3.69 percent.

The dollar is flat at 90.53 against the yen. The euro is back under pressure, down .0037 to 1.3488 against the buck.

Among the stocks to watch, Williams Sonoma (WSM) is up 2 percent after reporting better-than-expected earnings and announcing an increase to its dividend. Gamestop (GME) edged up 1 percent after receiving a positive mention in Barron’s. Wal-green’s (WAG), KB Homes (KBH), and Carnival (CCL) might see action today, ahead of earnings tomorrow before the bell.
