NEW YORK (AP) _ Bond prices fell Wednesday as investors showed interest in stocks, boosting equity markets substantially higher.

The price of the benchmark 10-year Treasury note fell 1/4 point, or $2.50 per $1,000 in face value. Its yield, which moves in the opposite direction, rose to 5.24 percent compared with 5.20 percent late Tuesday.

The 30-year Treasury bond fell 15/32 point to yield 5.70 percent, up from 5.67 percent a day earlier, according to Moneyline Telerate.

The dropoff in bonds coincided with renewed strength in stocks, which had been slumping on fears of Mideast violence and uncertainty about quarterly earnings. A positive earnings outlook by Sears Roebuck sparked new optimism among investors Wednesday.

The Dow rose 173 points, its biggest gain in more than a month, to close at 10,382. The Standard & Poor's 500 index climbed 13 points to 1,130, while the Nasdaq composite index gained 25 points to close at 1,767.

In other trading, the benchmark 2-year note fell 1/32 point to yield 3.44 percent, up from Tuesday's 3.43 percent. Intermediate maturities fell between 1/8 point and 6/32 point.

Yields on one-month Treasury bills were 1.71 percent as the discount was unchanged at 1.69 percent. Yields on three-month Treasury bills were 1.70 percent as the discount rose 0.01 percentage point to 1.68 percent. Six-month yields were 1.97 percent, as the discount fell 0.03 percentage point to 1.93 percent.

Yields are the interest bonds pay by maturity, while the discount is the interest at which they are sold.

The federal funds rate, the interest on overnight loans between banks, was unchanged at 1.69 percent.

In the tax-exempt market, the Bond Buyer index of 40 actively traded municipal bonds rose 5/32 to 103 1/16. The average yield to maturity fell to 5.37 percent from 5.38 percent.
