NEW YORK (Reuters) - Value stocks notched their best one-day performance against their growth-focused peers ever, by one measure, after Monday’s news of an effective vaccine against the coronavirus sent investors into shares of companies expected to benefit the most from an economic recovery. Pfizer Inc PFE.N said on Monday its experimental COVID-19 vaccine was more than 90% effective, a potentially major victory in the fight against a pandemic that has killed more than a million people, hammered the world’s economy and upended daily life. Shares of companies that have struggled for months under coronavirus-fueled lockdowns surged, with the S&P 500 index .SPX closing just shy of a record, and some investors believe the moves may have further to run if the vaccine news continues to be favorable. Value stocks tend to be companies that are more sensitive to the economy’s fluctuations. Here’s a look at today’s market action, as well as how value and growth have stacked up through the years.
