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 19.6x Exit PE.
In-depth Analysis How we analyze
Valuation Analysis: MKSI is currently trading at $213.47, which is considered fair relative to its 30-day fair value range of $194.93 to $254.46. From a valuation perspective, the stock is trading at a discount (Forward PE: 10.8) compared to its historical average (19.6). Remarkably, the market is currently pricing in an annual earnings decline of 18.0% over the next few years. This pessimistic expectation contrasts with the company's recent 196.5% earnings growth, suggesting potential undervaluation if the company simply maintains stability.
Technical Outlook: Technically, MKSI is in a strong downtrend. Immediate support is located at $173.13, while resistance sits at $222.30.
Market Sentiment: MKSI scores 82/100 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 $332.71 (+55.9%). Combining these factors, the current setup offers a favorable risk/reward ratio for buyers.
