🧮 MCK P/E Ratio Calculation
What is the P/E Ratio?
The Price-to-Earnings (P/E) Ratio is one of the most widely used valuation metrics. It tells you how much investors are willing to pay for each dollar of a company's earnings. Zyberno calculates P/E using trailing twelve month (TTM) diluted earnings from official SEC filings.
How to Interpret the P/E Ratio
Low P/E (Under 15x)
May indicate undervaluation, or the market expects declining earnings. Common in mature, slow-growth industries.
Average P/E (15-20x)
Roughly in line with historical S&P 500 average. Suggests fairly valued with moderate growth expectations.
High P/E (20-35x)
Investors expect above-average earnings growth. Common for technology companies and market leaders.
Very High P/E (35x+)
Extreme growth expectations priced in. Significant valuation risk if growth slows.
PEG Ratio: P/E Adjusted for Growth
The PEG Ratio addresses a key limitation of P/E by factoring in earnings growth. A PEG of 1.0 suggests fair value; below 1.0 may indicate undervaluation, while above 2.0 suggests a premium price for growth.
P/E Ratio Limitations
The P/E ratio doesn't work for companies with negative earnings. It can be manipulated by one-time charges or gains, and it doesn't account for debt levels or growth rates. Use P/E alongside PEG ratio, EV/EBITDA, and Owner Earnings yield for a complete picture.
