Put DGX beside peers and holdings, graph the same metric, and keep your notes with the evidence.
Daily closes. Earnings/event dots are placed inline.
Industries move in repeating boom-and-bust cycles. This shows where this stock’s industry sits in that cycle, stage by stage (recovery → expansion → supercycle → steady → deceleration → contraction), from its fundamentals (orders, revenue, capital spending), not the stock’s price.
A booming industry is a tailwind for the names in it; a contracting one is a headwind. Companies in the same industry tend to rise and fall together with the cycle, the way a tide lifts and lowers every boat in the harbor at once, so a large part of a stock’s swing can come from where its industry sits rather than from the company itself. It’s context for reading the company’s results, not a buy/sell call. Full explanation →
Health Care is in steady. Describes the industry's cycle state, not a call on this stock.
The stage band shows the industry’s cycle over the chart’s timeline (each color a stage); a ▼ marks a quarter its growth inflected down — amber is an unconfirmed watch, red is confirmed the next quarter. Use “Overlay cycle on chart” to tint the price chart by stage. The industry’s fundamentals, not a signal on this stock.
The reason to own it still holds.
View ThesisRevenue growth is slowing — up about 9% over the past year and decelerating.
View GrowthRanks among the strongest in its industry on quality — around the top 18%.
View QualityManagement screens strong on earnings delivery, margins.
View ManagementExpectations look reasonable — what the market is pricing in sits in line with or below what analysts forecast.
View ValuationModerate volatility — typically moves about 1% a day.
View RiskDGX's consumer testing engine has to keep compounding to justify the price. Revenue grew 10% year over year in the latest quarter. The company beat earnings estimates by 5.3% in Q3. It trades at 23x earnings versus a 24x peer median. The price reflects less growth than we forecast. A 15% Medicare fee cut threatens revenue growth. Peer multiples imply a price about 17% below where it trades. Our read remains intact. This read is provisional.
