US stock futures took a leap higher Thursday after weekly initial jobless claims fell more than forecast in a reassuring update on the health of the US labor market. Futures tied to the S&P 500 ( ES=F ) rose 0.7%, while those on the tech-heavy Nasdaq ( NQ=F) jumped 0.9%. Dow Jones Industrial Average futures ( YM=F ) were up about 0.4%.

The normally routine labor market update found itself in the spotlight Thursday amid increasing scrutiny on the labor market, as last week's sluggish non-farm payrolls update served as one of the earliest catalysts of the recent declines.

Government data showed that there were 233,000 initial jobless claims in the week ending Aug. 3, down from 250,000 last week and fewer than what economists had forecast.

The number could add a fresh jolt into Thursday's trading. Wall Street saw a comeback attempt falter on Wednesday, as stocks faded into the close and ended up with sizable declines. The moves — from big gains to significant losses — continued a turbulent stretch that has pervaded in markets for much of the past week.
