NEW YORK, March 23, 2026, 10:13 EDT
Last week’s slip under the S&P 500’s 200-day moving average has market analysts at odds—some see the start of a bigger correction, others are eyeing a possible bounce. On Monday, that split got starker. Stocks rebounded, oil dropped, and President Donald Trump announced a delay to planned strikes on Iranian power plants and energy facilities.
The 200-day moving average—basically the mean close across the prior 200 sessions—just snapped. Funds and risk managers lean on this marker for a read on the long-term trend. This time, though, the break follows four straight down weeks, spiking oil, and a hawkish shift from central banks, which amps up the significance well beyond a typical chart blip.
Shooting higher by 9:40 a.m. ET Monday, the S&P 500 climbed 1.52% to 6,605.26; the Dow Jones Industrial Average picked up 1.66%. The Nasdaq Composite jumped 1.77%, with the CBOE Volatility Index retreating from its recent two-week peak. Brent crude tumbled as much as 15%, trading at $96 a barrel, and U.S. crude slid 13.5% to $85.28, coming after Trump’s five-day reprieve.
Lance Roberts, chief investment strategist at Real Investment Advice, flagged the real question: “what kind of break is this?” In his analysis of a dozen instances since 2000, he counted seven persistent breaks that led to an average one-month loss of 5.3% and a 12-month average drop of 4.0%. The five other, more fleeting breaks? Those saw the market rally, with an average 12-month gain of 19.8%. RIA
Phil Rosen at Inc. struck a more optimistic note, pointing out that the S&P 500 slipped under its 200-day moving average for the first time in 214 trading sessions. He referenced TradingView numbers—16 such drops in the last ten years, many of which were followed by rebounds instead of extended declines. Rosen also flagged that both the Dow and Nasdaq wrapped up last week under their 200-DMA too.
Andrew McElroy, Matrixtrade’s chief analyst, took a tighter view in his Seeking Alpha note. He flagged a possible rebound around 6,500, but called resistance up at 6,764 to 6,775—pointing to persistent inflation and waning Fed cut bets as the roadblocks for further gains. For a bigger-picture entry, he’s eyeing 6,147.
Other analysts echoed the unease on Monday. Chris Larkin, managing director of trading and investing at E*TRADE from Morgan Stanley, described markets as “headline-driven.” Aaron Costello, who leads Asia at Cambridge Associates, cautioned that investors have begun factoring in the risk that stockpiles “will eventually be depleted” should the conflict persist.

This wasn’t a one-off. Inc. noted both the Nasdaq and Dow dipped under their 200-day averages, and that Monday’s bounce only lifted a handful of names: American Airlines and United Airlines both surged over 4.5%. Cruise stocks leapt more than 5.5%. On the other side, oil names like Exxon Mobil, Chevron, and Occidental Petroleum slipped as crude prices pulled back.
The bigger worry here: the rebound could quickly unravel. Iran’s Fars News Agency pushed back on Trump’s claims about backchannel talks with Washington. Over at Goldman Sachs, analysts warned that if the Strait of Hormuz stays choked off, Brent might stick close to $110 through March and April. In a worst-case outcome, prices could spike to $135—a move that would likely hit stocks again and push expectations for rate cuts even further out.
Right now, there’s a technical break, a spark from geopolitics, and still no clear resolution. Roberts called the 200-DMA “not a verdict” but more of an open question; Monday’s bounce only addressed a piece of that puzzle. RIA
