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 21.9x Exit PE.
In-depth Analysis How we analyze
Valuation Analysis: MKSI is currently trading at $297.45, which is considered oversold relative to its 30-day fair value range of $312.85 to $397.32. From a valuation perspective, the stock is trading at a discount (Forward PE: 19.1) compared to its historical average (21.9). Remarkably, the market is currently pricing in an annual earnings decline of 4.4% 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 $256.16, while resistance sits at $349.01.
Market Sentiment: MKSI has a weak technical setup (25/100), with bearish trendlines and momentum suggesting caution for short-term entries. Wall Street analysts see significant upside, with an average price target of $412.31 (+40.6%). The stock is fairly positioned - fine to hold existing positions or accumulate slowly on dips, but not an urgent buy.
