Quest Diagnostics stock closed the last session on the New York Stock Exchange on September 16, 2026 with a mid-teens percent gain from its level before the latest quarterly report, while the broader S&P 500 index fell roughly 0.6 percent that day. The shares benefited from a strong second-quarter earnings report that beat analyst expectations on both revenue and earnings, according to Yahoo Finance. Today, Quest Diagnostics stock trades ahead of the open with attention on macroeconomic data and sector sentiment rather than a company-specific catalyst.
September 16, 2026 in numbers
Quest Diagnostics Inc. (ISIN US74834L1008, NYSE: DGX) recently reported second-quarter revenues of USD 3.04 billion, up 10.2 percent year on year, and a solid beat versus analyst expectations, as highlighted by Yahoo Finance. The stock is up 16.4 percent since that report and recently traded at USD 244.31 per share; this level stands above the closing price before the earnings release and marks a clear outperformance versus the S&P 500 over the same period. On September 16, 2026, major US stock indexes closed lower, with the Dow Jones Industrial Average falling about 1.2 percent and the Nasdaq Composite slipping modestly, according to Las Vegas Sun. That backdrop underscores that Quest Diagnostics shares have been moving against a softer wider market in recent sessions.
Macro and health care cues today
Today, Quest Diagnostics stock heads into the open without a scheduled company-specific event, so trading is likely to be shaped by broader factors such as US economic data and moves in major health care benchmarks. Recent market coverage shows investors digesting signals from the latest Federal Reserve policy meeting and economic releases as US indexes trade under pressure, as described by Zacks. For Quest Diagnostics, the strong earnings momentum and defensive nature of diagnostic services may attract attention if volatility in the broader market persists this week.
