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 →
Real Estate 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.
Primary pillar under pressure — Achieve full-year 2026 revenue of $3.78B to $3.82B: Revenue guidance: $3.71B to $3.75B.
View ThesisRevenue growth is accelerating — up about 20% over the past year.
View GrowthRanks in the weakest quality tier of its industry — roughly the bottom 31%, softest on free-cash-flow margins.
View QualityManagement screens strong on capital allocation, earnings delivery, guidance credibility.
View ManagementExpectations look high — the market is pricing in about 51% growth a year, above the roughly 12% analysts expect, leaving little room for error.
View ValuationThis stock is volatile — it swings about 2% on a typical day and fell roughly 62% in its worst 12-month stretch.
View RiskCSGP’s case rests on strong, cash-backed performance, though revenue growth has slowed across recent quarters. Q3 revenue grew 14% year over year, down from 18% in Q2 and 23% in Q1. Q3 earnings beat consensus, yet bookings fell to $37 million from $84 million a year earlier. CSGP trades at 27× P/E versus a 19× peer median, with expectations exceeding our growth forecast. The multiple premium faces pressure because 2026 revenue guidance falls below the stated full-year target. Our model puts the next-quarter miss probability near 22%. Peer multiples imply a price about 51% below where it trades; the thesis is on watch.
