NEW YORK, March 11 (Reuters) - U.S. stocks eked out a second day of gains on Wednesday after JPMorgan became the second big bank to cite profitability, but oil slid 7 percent on further signs of weak global demand and rising inventories.
U.S. government debt prices rallied on a revived safety bid for lower-risk investments and as a sale of 10-year notes eased supply worries, while the dollar fell on the lack of any new fundamental economic news to prompt demand for the greenback

But comments by JPMorgan Chase <JPM.N> Chief Executive Jamie Dimon to CNBC television reversed a broad decline in stocks and came after a speech in which he said the bank's bond department had just had its two busiest months ever.
Dimon's comments that JPMorgan was profitable in January and February echoed comments by Citigroup's chief executive, Vikram Pandit, that had fired Tuesday's rally.
Dimon also said he sees "modest signs" of an economic recovery, helping JPMorgan shares to rise 4.6 percent and spuring a 3.1 percent advance in the KBW banking index <.BKX>.
Dimon "calmed the markets down, he was the voice of reason," said Angel Mata, managing director of listed equity trading at Stifel Nicolaus Capital Markets in Baltimore.
