VIX Roils Markets Again With Biggest Jump Since February Rout

(Bloomberg) -- Wall Street’s “fear gauge” rose the most since February, raising alarms that investors could be in for a repeat of the market meltdown seen earlier this year.

The Cboe VIX Index’s 44 percent jump Wednesday to 22.96 leaves it a good distance from its peak close in early February of 37.32. But the speed of the increase, on top of advances in the past few sessions that ended a midyear hibernation, may give traders pause.
