Stocks stall as traders await Fed chair Warsh and Iran deal

U.S. stocks traded in narrow ranges on May 21, 2026, as investors paused ahead of Federal Reserve chair Kevin Warsh's first public remarks and sought clarity on a fragile U.S.-Iran diplomatic deal.

The early session was muted. Traders booked some profits after a recent rally and moved to the sidelines while awaiting clearer headlines. Walmart fell about 7% and heavyweight tech names including Nvidia pressured indexes, even as semiconductor shares held gains.

Market participants described the selling as contained rather than panic, with institutional capital digesting recent record highs. Attention focused on a White House event scheduled for tomorrow where Warsh will be sworn in and is expected to outline his initial approach to Federal Reserve policy.

Investors are watching for any signals about potential changes to the Fed's balance sheet that could affect liquidity and trading flows. Conflicting reports about uranium stockpiles added uncertainty in the energy sector and increased attention to crude oil headlines.

Technical readings influenced intraday moves. The Dow reached about 50,200 twice but failed to sustain a move above 50,000; traders identified an upside trigger near 50,250 and a downside trigger around 49,850. Resistance was cited roughly between 49,900 and 50,000, with ceilings in the 50,400–50,500 range and the all-time high at 50,544. Support levels included a gap fill near 49,500, pivots at 49,000–49,100, momentum support near 48,500 and a deeper pivot at 48,000.

The Nasdaq found intraday support at its two-hour 50-period moving average around 29,050 and would need to rise above about 29,400 for a clearer recovery. Current intraday resistance sat near 29,500–29,600, while a drop below 29,000 would likely extend selling. Shorter-term supports included 28,500 and the 28,000 psychological pivot, with prior all-time high support around 26,200–26,300.

The S&P 500 tracked a similar pattern. A break above 7,430–7,450 would indicate renewed upside momentum, while a move below 7,400 could lead toward 7,320–7,340. Daily resistance was noted at about 7,525 and key supports ranged from 7,250–7,260 down to earlier highs near 7,000–7,020.

Technicians noted that weakness remained narrow and selective, with semiconductors among the few groups extending gains and helping limit broader losses. Traders planned to monitor Warsh's initial remarks and energy headlines for developments that could influence liquidity conditions and market direction.
