NEW YORK, Nov 9 (Reuters) - The 30-Year Treasury bond turned negative on Monday as government debt prices gave up some of the boost that followed a strong 3-Year note auction.

A sharp rally in U.S. stocks helped diminish the safe-haven allure of government bonds.

The benchmark 10-year Treasury note's price, which moves inversely to its yield, traded up 3/32 for a yield of 3.49 percent US10YT=RR, versus 3.51 percent late on Friday.
