After-hours surges and plunges that have whipsawed gold and silver prices over the past two weeks are unnerving traders.
Silver futures sank as much as 10%, as more than 25-million ounces of the precious metal traded within a minute just after 7 AM in Singapore Friday. Last week, gold fell below its 200-day moving average after 1.8-million ounces were transacted in a minute at 4 AM in New York. A day later, gold spiked after a similar trade involving more than 800 000 oz.
