Trading above fair value
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 20.0x Exit PE.
In-depth Analysis How we analyze
Valuation Analysis: MKSI is currently trading at $235.41, which is considered extended relative to its 30-day fair value range of $166.92 to $220.49. From a valuation perspective, the stock is trading at a premium (Forward PE: 26.0) compared to its historical average (20.0). At these levels, the market is pricing in 9.0% 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 $200.00, while resistance sits at $246.35. Short-term momentum is weak, with the stock down 3.5% recently.
Market Sentiment: MKSI has a strong technical setup (60/100), with favorable trendlines, momentum, and price action for short-term traders. The stock is fairly positioned - fine to hold existing positions or accumulate slowly on dips, but not an urgent buy.
