It was an inside Tuesday session in the S&P 500 index futures, with neither bulls nor bears gaining significant ground. Although bears won by the close, after hours action told a different story.

Overnight, bulls and bears tugged at the index futures, largely setting the tone and range for the regular session. After the opening bell, bulls bought the dip near the premarket low, but sellers pushed right back to print the low of 6573.50. Bulls then mounted a slow choppy rally with higher lows, briefly pushing into the green before bears pushed back into mid-range. Support held at the psychological 6600 level in the afternoon, allowing bulls to barely reclaim green territory. Sellers had the final word, driving a slow steady decline in the final hour.

The session closed below the day’s midpoint at 6606, down 28.75 handles. However, after hours reports of a potential ceasefire in Iran sent futures surging to 6680.50, turning into some chop near that high as the futures session drew to a close.

Tomorrow brings February’s import price index at 8:30 AM ET along with a small handful of earnings reports.

Among the top components of the index, Walmart Inc (NYSE: WMT) stood out as the biggest gainer, rising $1.32 or 1.09% to close at $122.05.

That performance was still better than the cash index’s 0.34% decline.

On the other hand, Alphabet Inc (NASDAQ: GOOGL) was the biggest loser, falling $11.76 or 3.89% to close at $290.44.
