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 21.3x Exit PE.
In-depth Analysis How we analyze
Valuation Analysis: MKSI is currently trading at $303.17, which is considered extended relative to its 30-day fair value range of $259.35 to $297.31. The stock's valuation (Forward PE: 20.6) is in line with its historical norms (21.3). Remarkably, the market is currently pricing in an annual earnings decline of 1.1% over the next few years. This pessimistic expectation contrasts with the company's recent 53.2% earnings growth, suggesting potential undervaluation if the company simply maintains stability.
Technical Outlook: Technically, MKSI is in a strong uptrend. Immediate support is located at $277.55, while resistance sits at $326.83. Short-term momentum is weak, with the stock down 3.4% recently.
Market Sentiment: MKSI has a strong technical setup (75/100), with favorable trendlines, momentum, and price action for short-term traders. Wall Street analysts see significant upside, with an average price target of $357.42 (+17.9%). The stock is fairly positioned - fine to hold existing positions or accumulate slowly on dips, but not an urgent buy.
