How this is calculated: We use a Growth Decay Model: starting with analyst consensus growth (adjusted above) and gradually slowing it down to a long-term terminal rate (4%) by Year 5. This provides a more realistic valuation than assuming constant hyper-growth. We then apply a 25.0x Exit PE.
In-depth Analysis How we analyze
Valuation Analysis: CSGP is currently trading at $27.72, which is considered oversold relative to its 30-day fair value range of $28.27 to $31.88. From a valuation perspective, the stock is trading at a discount (Forward PE: 15.6) compared to its historical average (26.3). Remarkably, the market is currently pricing in an annual earnings decline of 15.9% over the next few years. This pessimistic expectation contrasts with the company's recent 1261.0% earnings growth, suggesting potential undervaluation if the company simply maintains stability.
Technical Outlook: Technically, CSGP is in a strong uptrend. Immediate support is located at $26.52, while resistance sits at $29.91.
Market Sentiment: CSGP scores 70/100 on our bottoming-setup gauge — the chart has corrected and is stabilizing (RSI reset, momentum turning up), historically a favorable entry zone. Wall Street analysts see significant upside, with an average price target of $37.30 (+34.6%). The stock is fairly positioned - fine to hold existing positions or accumulate slowly on dips, but not an urgent buy.
