NEW YORK, Oct 16 (Reuters) - Stocks across the world bounced back on Tuesday, supported by strong earnings results and expectations, while oil prices rose as evidence of higher U.S. production was overshadowed by concerns about supply from Iran and Saudi Arabia.
Despite the rally in stocks, U.S. Treasury yields were little changed.
European shares pulled up from Monday's 22-month lows , partly on expectations that the reporting season will deliver double-digit earnings growth. A rebound in Italian assets helped battered equities find firmer ground.

"A couple of inputs that caused a sell-off in the last two weeks, such as rising interest rates, higher oil prices and the dollar, have calmed down to rational levels," said Art Hogan, chief market strategist at B. Riley FBR in New York.
"The market may be able to positively respond to that as we work our way through the earnings season."
Willie Delwiche, investment strategist at Baird in Milwaukee, said Tuesday's gains were the result of sharp selling over the past weeks.

Emerging market stocks lost 0.86 percent. MSCI's broadest index of Asia-Pacific shares outside Japan closed 1.11 percent lower.
Crude futures rose in choppy trading as expectations of higher U.S. shale output and inventories were more than offset by worries over looming U.S. sanctions on Iran and growing tensions with top oil producer Saudi Arabia.
U.S. Senator Lindsey Graham accused Saudi Crown Prince Mohammed bin Salman of ordering the murder of Saudi journalist Jamal Khashoggi and said the prince was jeopardizing relations with the United States.
