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.

P/E Ratio = Stock Price ÷ Earnings Per Share (TTM)
Using diluted EPS which accounts for stock options and convertible securities

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.

PEG Ratio = P/E Ratio ÷ Earnings Growth Rate
SO: 22.77x ÷ -9.52% = -999.00

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.
