BOSTON, Aug 5 (Reuters) - U.S. stocks and oil prices rebounded sharply on Thursday as unemployment claims declined and the trade deficit widened - positive economic data in the face of rising COVID-19 cases and signals of declining Federal Reserve stimulus. The number of Americans filing new claims for unemployment benefits declined further last week, while layoffs dropped in July to their lowest level in just more than 21 years. read more The U.S. trade deficit surged to a record high in June as businesses boosted imports to rebuild inventories. read more The Dow Jones Industrial Average (.DJI) rose 271.58 points, or 0.78%, to 35,064.25, the S&P 500 (.SPX) gained 26.46 points, or 0.60%, to 4,429.12 and the Nasdaq Composite (.IXIC) added 114.58 points, or 0.78%, to 14,895.12. "Yesterday"s record high reading on the Services PMI and today"s unemployment claims data have reinvigorated confidence on the economic growth front," Dave Donabedian, chief investment officer of $92 billion CIBC Private Wealth U.S., wrote in an email. A measure of U.S. services industry activity jumped to a record high in July, boosted by the shift in spending to services from goods. read more "Investors definitely are keeping an eye on the Delta variant, but mostly view it as a speed bump for the economy rather than a showstopper," Donabedian said. Goldman Sachs market strategists raised their year-end and 2022 price targets for the S&P 500 Index, citing "the combination of higher-than-expected S&P 500 earnings and lower-than-expected interest rates." Still, investors want to know how low rates will stay, and for how long. On Wednesday, U.S. Federal Reserve Vice Chair Richard Clarida, a major architect of the Fed"s new strategy, said he felt conditions for raising interest rates could be met by the end of 2022, raising expectations that the central bank could scale back its bond-buying program soon. read more A key indicator is due on Friday with the U.S. non-farm payrolls report, seen as key to the U.S. central bank"s policy stance. read more "Everyone is on pins and needles waiting for tomorrow"s jobs report, which will clearly dictate how the markets close out the week," Michael S.
