Stock futures rise slightly as investors prepare for Fed’s preferred inflation gauge: Live updates

Stock futures rose on Friday morning as the major averages head for weekly losses and investors anticipated a reading of the Federal Reserve's preferred inflation gauge.

Futures tied to the Dow Jones Industrial Average advanced 151 points, or 0.38%. S&P 500 futures and Nasdaq 100 futures climbed just over 0.47% and 0.6%.

In after-hours trading, medical device maker Dexcom plunged about 38% after releasing disappointing fiscal full-year guidance. Footwear company Deckers reported fiscal first-quarter earnings and revenue that exceeded analysts' expectations, boosting shares by roughly 10%.

Stocks are poised to end the week with declines, as investors on Thursday added to the previous session's steep losses by dumping some megacap tech and artificial intelligence-tied stocks. The activity seemed to be part of a broader rotation into small caps and more cyclical areas of the market.

The S&P 500 and tech-heavy Nasdaq Composite slid by about 0.5% and 0.9%, respectively, on Thursday. The 30-stock Dow bucked the trend and added roughly 81 points, or just 0.2%.

"Volatility came back with a vengeance this week as selling pressure in the megacap space dragged down the broader market," LPL Financial chief technical strategist Adam Turnquist said in a note to clients, adding that overbought conditions have also contributed to the recent weakness. "Counterbalancing weakness in these heavyweight names poses a challenge for the rest of the market."

The broad-market index is down 1.9% this week, while the Nasdaq has lost nearly 3.1%. The Dow is down roughly 0.9% week to date.

On Friday at 8:30 a.m. ET, traders will watch for June's personal consumption expenditures report, an inflation reading that's preferred by central bank policymakers. On
