Trading above historical range
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 21.5x Exit PE.
In-depth Analysis How we analyze
Valuation Analysis: MKSI is currently trading at $420.56, which is considered extended relative to its 30-day fair value range of $302.03 to $364.72. From a valuation perspective, the stock is trading at a premium (Forward PE: 28.1) compared to its historical average (21.5). At these levels, the market is pricing in 9.4% 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. The price is approaching resistance at $418.00. A breakout above this level would be a bullish signal, while rejection here could lead to consolidation. The stock is showing strong short-term momentum, up 3.5% recently.
Market Sentiment: MKSI has a strong technical setup (60/100), with favorable trendlines, momentum, and price action for short-term traders. However, the stock is trading significantly above the average Wall Street target of $359.92. Current signals suggest waiting for a better entry point before initiating new positions.
