Wednesday’s S&P 500 index futures session saw another volatile day with an expanded range, flipping between losses and gains, but bulls ultimately secured a modest advance by the close.

Overnight, bulls built momentum, lifting futures steadily above Tuesday’s close for a regular session open surpassing Tuesday’s high. Support held near that level early on, and buyers rallied past the premarket high, reaching a session peak of 6766.75 despite fresh headlines of global trade tensions. The rally faltered, with selling pressure soon emerging. After testing support near Tuesday’s high again, sellers gained traction after the lunch hour during Fed’s Miran speech, pushing the index into the red to a low of 6651.50.

Buyers quickly countered, driving a recovery back into positive territory. The final hours oscillated between 6700 and 6725, hovering near Tuesday’s high once again. Late selling hit after closing imbalances were announced, but dip-buyers quickly stepped in, limiting the pullback. The session closed near the day’s midpoint at 6715, up 28.50 handles.

Thursday brings more morning earnings, fedspeak throughout the day, and, if the government shutdown ends, September’s PPI report.

Among top index components, Alphabet Inc (NASDAQ: GOOGL) led as the biggest gainer, rising $5.58 or 2.27% to close at $251.03.

That outpaced the cash index’s 0.44% gain by a fabulous five times. 

On the other hand, Amazon.com Inc (NASDAQ: AMZN) was the biggest loser, slipping $0.82 or 0.38% to close at $215.57.
