Gero said he also suspects investors might turn to gold as a hedge more quickly now than they did in 1987. He added that if a similar stock-market sell-off were to occur again, there are a number of factors now that could exacerbate the situation, such as algorithm trading and the end of daily price limits in many futures markets. When those price limits - both up and down -- were hit in the past, markets were shut down for a certain number of minutes to allow adjustments in margin calls and for market participants to recover, Geri explained.
