Price, fair value, and the multiples that frame it on the same time axis. Scroll over the price chart to zoom.
Daily closes. Earnings/event dots inline.
A consensus fair price across 9 valuation methods, at three horizons. As of 2026-09-04. Estimates are diagnostics, not price targets. Short-horizon estimates are close to coin-flips, so confidence is a method-agreement read, not a prediction.
Today's peer multiple on trailing earnings, with no growth credited. This is the headline read.
Adds projected growth, so it leans optimistic by design. Read it as upside context, not a base case.
We take the 12-month fair value above and grade our own number — how the market prices this name versus what we'd justify, and where the two diverge.
At $31 CSGP trades at 30× p/e — 1.5× the 20× p/e peer median. The market is re-rating it beyond its own range; our $20 fair value is low-confidence here. Analysts target $26–$46. Note: our $20 fair value sits below the entire analyst range ($26–$46). The flat-multiple read looks rich, but earnings are inflecting up — trailing growth is accelerating and forward estimates confirm — so we've softened our read rather than brand an accelerating name expensive. Not investment advice.
One valuation read at a 12-month horizon, plus how price compares to peers and the company's own history.
Score 100 = cheapest in the cohort, 0 = richest. Bars are filled left-to-right based on the peer-relative score (or PEG/self-history where shown).
Each method's implied share price per horizon. Provisional rows use a projected (historical-CAGR) growth input rather than analyst or management guidance.

A “consensus-then vs. actual-now” overlay is on the way — what our valuation estimate said on a past date versus where the price actually landed.
Not investment advice. Scores describe historical and current data; they are not forecasts of future returns. Consult a licensed advisor before making investment decisions.
A long-thesis check that carries the widest uncertainty of the three horizons.

$26.00 – $46.00 (median $34.00) · 10 analysts · as of 2026-08-24
Only expensive valuation — not the full expensive x weak x turbulent stack.
For similar setups historically (n=20,154): about 33% saw a 20%+ drawdown, and roughly 76% of those did not recover within the year. These are historical base rates for the cohort, not a forecast of this stock.
Looks more expensive than peers.
Self-history needs ~20 months of data.
