NEW YORK (AP) -- U.S. stocks are falling at midday as investors worry over the details of a new bailout plan for Greece.
The Dow Jones industrial average is down 44 points at 12,921 at midday Wednesday. The day before, it briefly touched 13,000 for the first time since May 2008. The Dow has been trading at or near four-year highs for three weeks.
The Standard & Poor's 500 is down 6 points at 1,356. Energy and health care were the only sectors gaining ground. The Nasdaq composite index lost 15 points to 2,933.
Investors are worrying that Greece's new $172 billion deal may not be enough to keep the debt-laden from eventually defaulting and possibly exiting the euro. European markets are broadly lower.
