Credit Suisse High Yield Bond Fund shares rise 1.65% premarket after Citigroup's profit beat estimates and share buyback plans.

Credit Suisse High Yield Bond Fund rose 1.65% in premarket trading. Citigroup's shares briefly touched their highest since the 2008 financial crisis after the bank beat Wall Street estimates for second-quarter profit and said it plans to buy back at least $4 billion in stock. The stock rose as high as $90.69 on Tuesday after the third largest U.S. lender reported market-beating earnings, driven by windfalls in its trading and investment banking businesses.
