Markets: mixed signals right now
End‑March closes left the S&P 500, Dow and Nasdaq 100 below their 10‑month moving averages — a technical flip that historically signals a lower‑return regime (roughly 3.4% vs 9.9% when above that trend). At the same time, markets spiked on signs of easing Iran tensions and short‑term rallies put names like Kiniksa, Quanta Services and Sandisk in focus. (x.com) (youtube.com)
U.S. indexes posted one of their biggest single-day gains to close March as the Dow rose about 1,125 points, the S&P 500 gained 2.91% to 6,528.52, and the Nasdaq Composite jumped 3.83% on March 31 amid reports of potential de‑escalation between the U.S. and Iran. (cnbc.com) Oil prices reversed course the same day, with U.S. crude (WTI) sliding roughly 1.5% to trade near $101 a barrel after the Iran developments. (bloomberg.com) That dip in oil capped a month of extreme energy volatility: WTI logged about a 51% gain for March before the late pullback, marking one of its largest monthly moves in years. (cnbc.com) Quanta Services reached record highs earlier in March — trading as high as roughly $574 and drawing a TD Cowen price‑target boost that coincided with a reported backlog north of $40 billion and a market cap estimate in the tens of billions. (markets.financialcontent.com) Sandisk’s stock has been extremely volatile: recent coverage noted a roughly 141% three‑month gain even as the company scheduled a fiscal Q3 earnings call for April 30, keeping the name in traders’ crosshairs. (finance.yahoo.com) Kiniksa’s shares moved higher after its fourth‑quarter report showed ARCALYST product revenue of $202.1 million in Q4 and $677.6 million for full‑year 2025, with 2026 ARCALYST guidance in the $900–$920 million range and a reported cash balance near $414.1 million. (stocktitan.net) Technical scans across major analytics platforms showed bearish to neutral signals on daily and weekly timeframes entering April, with composite technical summaries tilting toward “sell” or “strong sell” on several widely used services.
