NEW YORK (Reuters) - Stocks brushed up against last week’s record on Monday and an index of commodity prices closed at its highest since March as more vaccine news gave investors hope economic activity could resume globally at a faster clip than many feared. AstraZeneca said its COVID-19 vaccine, cheaper to make, easier to distribute and faster to scale-up than its rivals, could be as much as 90% effective. “This means we have a vaccine for the world,” said Andrew Pollard, director of the Oxford University vaccine group that developed the drug. Assets from emerging markets reacted strongly to the news, as it allays concerns over the distribution logistics of a vaccine for developing countries.

Stocks got an extra boost after reports that U.S. President-elect Joe Biden plans to nominate former Federal Reserve Chair Janet Yellen to become the next Treasury secretary. “Yellen should be a very strong advocate for more aggressive fiscal policy, and given her gravitas around Washington, it may make her the single most effective fiscal expansion advocate Biden could have picked,” said Tom Graff, head of fixed income at Brown Advisory in Baltimore.

Oil prices added to last week’s gains as traders anticipated the vaccine news would spur a recovery in energy demand. “Investors are ignoring near-term headwinds, chief among which are surging global COVID infections, and instead looking ahead to next summer,” said PVM analyst Stephen Brennock.
