Wednesday’s session in the S&P 500 index futures kept the back-and-forth alive, with bulls claiming the day and forging a quadruple top in the 6370-6380 range.

Bulls set the low at 6313.25 almost immediately overnight, doubling up with Tuesday’s low, then holding the index aloft premarket. The regular session opened slightly green with a choppy start, but bulls stood firm at unchanged. Morning reports of Apple’s $100B domestic manufacturing pledge helped spark a breakout, pulling the index futures higher.

Resistance hit at the recent triple-top around lunch, and the index chopped just below that level until a late push hit 6379.50 before profit-takers trimmed the gains. The session wrapped somewhat near the high at 6371, up 45.75 handles. 

Tomorrow is set to bring Q2 US productivity data at 8:30 AM ET and more earnings, including Eli Lilly and Co. (NYSE: LLY) at 6:45 AM ET.

Among the top components, Apple Inc (NASDAQ: AAPL) led the charge, surging $10.35, or 5.10%, to close at $213.28 as investors applauded its manufacturing pledge.

That outpaced the cash index’s 0.77% rise by a significant six times.

On the other hand, Eli Lilly And Co (NYSE: LLY) tanked as the biggest loser, dropping $19.58, or 2.56%, to close at $746.37 ahead of its Thursday morning earnings report.
