STOCK PRICES were mixed yesterday as investor optimism about second- quarter earnings gave way to nagging concerns about interest rates.

At the close of trading on Wall Street, the Dow Jones industrial average was up 17.73, or 0.2 per cent, at 10,552.56 after having risen more than 115 points earlier in the session. The blue-chip index shed 303 points during the week, as investors worried about interest rates and corporate profits. Broader market indicators were mostly lower.
