Stocks are modestly in the black midday, thanks to upbeat monthly jobs data that showed 850,000 jobs were added in June. The Dow Jones Industrial Average (DJI) is roughly 60 points higher, while the S&P 500 Index (SPX) notched another record high earlier in the day. The tech-laden Nasdaq Composite (IXIC) boasts a respectable lead as well, and all three major benchmarks are on their way to logging their second straight weekly wins. Amidst all this positive price action, Wall Street's "fear gauge," the Cboe Volatility Index (VIX), is heading for its lowest close since February 2020.
