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 $348.62, which is considered fair relative to its 30-day fair value range of $327.70 to $401.85. From a valuation perspective, the stock is trading at a premium (Forward PE: 24.3) compared to its historical average (21.9). At these levels, the market is pricing in 3.6% annual earnings growth. This growth rate appears achievable given the company's track record, suggesting the valuation is rational.
Technical Outlook: Technically, MKSI is in a strong uptrend. Immediate support is located at $329.01, while resistance sits at $447.62. Short-term momentum is weak, with the stock down 5.4% recently.
Market Sentiment: The stock shows a mixed technical setup (40/100), with neutral trendline and momentum signals. Wall Street analysts see significant upside, with an average price target of $405.77 (+10.1%). The stock is fairly positioned - fine to hold existing positions or accumulate slowly on dips, but not an urgent buy.
