Monday’s S&P 500 index futures session featured a promising overnight rally that was aggressively sold into at the open, turning a strong start into a modest red close.

Overnight, bulls built a steady advance with little resistance, peaking at 6932.25 just before the bell. Sellers flooded in immediately, triggering a sharp 70-handle swoon to 6864.25 and forming a triple-bottom with recent weekly lows. Dip-buyers mounted a solid rebound, recapturing over half the losses, only to meet fresh selling pressure.

Support held above the morning low, but the afternoon devolved into tight chop just below Friday’s close. The regular session finished in the lower half of the range at 6881, down 9.50 handles.

Tuesday brings the delayed November jobs report at 8:30 AM ET, plus a couple of earnings after the close.

Among top index components, Tesla Inc (NASDAQ: TSLA) emerged as the biggest gainer for the second straight day. After reports of full self-driving progress, the AI/EV company surged $16.35 or 3.56% to close at $475.31.

That performance was over three percent better than the cash index’s 0.15% decline.

On the hand, the biggest loser was Broadcom Inc (NASDAQ: AVGO) for the second day running. The chip designer extended its post-earnings slide, dropping $20.12 or 5.59% to close at $339.81.
