Getty Images Traders at Goldman had a good day on VIX bets.Earlier this year, Goldman Sachs booked a roughly $200 million gain in one day, partly on bets that a long-dormant gauge of volatility would surge, ending a protracted period of placidity on Wall Street. The prominent investment bank’s trading desk centered on derivative flows produced the big daily return as a so-called market maker rather than buying the assets for its own account, CNBC reported on Wednesday. The bets didn’t only include wagers on the Cboe Volatility Index VIX, -1.44% or VIX, but also trades on other derivative products. Often referred to as Wall Street’s “fear gauge,” the VIX saw a record spike in early February as the S&P 500 SPX, -0.20% Dow Jones Industrial Average DJIA, -0.30%and Nasdaq Composite Index COMP, -0.02% began a descent in to correction territory, defined as a 10% drop from a recent peak of at least 10%. The volatility gauge tends to move inversely to equity indexes.via
