SAN FRANCISCO (MarketWatch) -- Treasury prices rose on Friday, pushing yields down, as U.S. corporate earnings cast a shadow on the economic outlook and European leaders took no new steps at a summit as expected, weighing on the euro and equity futures to the benefit of U.S. debt. It all led bond traders to give attention to a key technical level for Asian buyers. Yields on 10-year notes 10_YEAR -1.42% , which move inversely to prices, fell 3 basis points to 1.81%.
