NEW YORK/LONDON (Reuters) - Silver prices jumped and global equity markets sank on Friday amid a growing battle on Wall Street between hedge funds and retail investors, while a dispute over COVID-19 vaccine supply in Europe cooled risk appetite.
Disappointing vaccine data from Johnson & Johnson (NYSE:JNJ) also hurt sentiment but the assault of retail traders using online forums to force hedge funds to reverse short positions - bets that stocks will fall - kept the market on edge.
Shares of GameStop Corp (NYSE:GME) and AMC Entertainment (NYSE:AMC) Holdings Inc surged again after Robinhood and Interactive Brokers (NASDAQ:IBKR) said they planned to ease restrictions after imposing buying halts on Thursday.
GameStop soared 67.9% to $325 a share, five times its closing price a week ago Friday, and AMC gained 53.7%, both in heavy trade. AMC was one of the most active stocks on the New York Stock Exchange. Volume on U.S. exchanges was 16.83 billion shares, up from the 10.6 billion average in the fourth quarter.
Silver rallied and was up 2% at $26.90 an ounce, taking gains to almost 10% since messages began to circulate on Reddit early Thursday urging retail investors to pile into the market and drive up prices.
Anxiety has grown as investors ask whether hedge funds will need to liquidate other positions to address losses in stocks they have shorted, said Michael Arone, chief investment strategist at State Street (NYSE:STT) Global Advisors in Boston.
"Once this short squeeze inevitably ends and there aren't any more greater fools to bid up these stocks, will retail investors get stuck holding the bag?" Arone asked.
"The unintended consequences of this potential volatility have markets on edge as we end the week," Arone said.
Arone added that investors need to take a giant step back as earnings are strong, the economy is improving, fiscal and monetary policy is supportive and vaccines are rolling out.

VACCINE DISPUTE
Delays in COVID-19 vaccine production have snowballed into a spat between Britain, the European Union and drugmakers over how best to direct limited supplies.
AstraZeneca (NASDAQ:AZN) Plc offered eight million more doses of its COVID-19 vaccine to the European Union after it unexpectedly announced supply cuts last week. But the bloc said that was far short of what was originally promised, an EU official told Reuters on Friday.
New variants of the novel coronavirus have prolonged lockdowns and delayed expectations of an economic rebound.
