While the first half of the Dow Jones Industrial Averageâs 998.5-point plunge probably reflected normal trading, the selloff snowballed because of orders sent to venues with no investors willing to match them, Leibowitz said in an interview on Bloomberg Television. âIf you look at the charts you can see fairly clearly where the trades came in,â he said from New York. âItâs that V-shaped drop where it came down and snapped right back up. You had some very high-cap stocks trading down 50 percent or large percentages in a split instant because there really was no liquidity in electronic markets.â The selloff briefly erased more than $1 trillion in market value as the Dow average tumbled 9.2 percent, its biggest intraday percentage loss since 1987, before paring the drop.
