U.S. stock futures pointed to a muted open Thursday, following one of the worst sessions of the year, as investors remained on edge ahead of the highly-anticipated May jobs report due Friday.

Economy: Weekly jobless claims fell by 6,000 to 422,000 in the latest week. While investors welcomed the slight dip in unemployment claims, the figure was not as low as economists were hoping for -- and it remained above the key level of 400,000 for the eighth straight week.
Companies: Shares of Corinthian Colleges (COCO) spiked 27%, while shares of Apollo Group (APOL, Fortune 500) rose 12%. Bridgepoint Education's (BPI) stock edged up 10%.
Investors will also keep on eye on major retailers including Target (TGT, Fortune 500), Gap (GPS, Fortune 500), Costco (COST, Fortune 500) and BJ's Wholesale (BJ, Fortune 500), as they release same-store sales data for May.
