Watch out below, say strategists

The Iran conflict and oil are calling the shots for the S&P 500 right now.

Consumer prices are in the spotlight for Wednesday, though these numbers might have limited utility given the surge in oil that's occurred since inflation was measured.

Oil and the Strait of Hormuz are calling the shots for stocks right now, as markets wait for news of a possible emergency oil release to calm markets.

Despite what's been a volatile period of news, the S&P 500 SPX has only declined 0.9% this year.

Mark Newton, head of technical strategy at Fundstrat, points to a daily chart of the Invesco QQQ Trust Series QQQ, which tracks the Nasdaq 100 NDX, that he said spells a picture of the choppy price action investors have endured in recent weeks. The QQQ will need a move back over 620, from Tuesday's close of 608, to get its uptrend back on track, while a move under 590 would flag a further selloff for stocks, he said.

Newton said investors should be watching if the S&P 500 SPX can surpass Tuesday's peak of 6,845. Markets will need to get past that to help any bounce for stocks, though he's not expecting a near-term push to new highs. If the market can get past 6,845, it can then get to 6,907 and then 6,952.

On the downside, a move below the December low of 6,717 would invite further selling pressure. In that case, Newton said traders would probably focus on November 2025 lows for the S&P 500 at 6,521.

Neil Wilson, strategist at Saxo Bank, said on the downside for the index, he's watching is Monday's low of 6,636. That marks "the first step" before 6,591, which is the 200-day simple moving average used to help confirm market direction, he said.

Breaking below that level opens the path to 6,500, which would be a 7.5% drop from all-time highs and mark the Oct. 10 intraday low when markets saw a big wobble on tariffs, said Wilson.
