Questions & Answers

Q: What is the P/E ratio and how is it calculated?

The P/E ratio compares a company's market value to its earnings, calculated by dividing market cap by net income or stock price by EPS. It indicates how much investors are willing to pay per dollar of earnings.

Q: Why is the P/S ratio important for valuing unprofitable companies?

Unlike the P/E ratio, the P/S ratio is used for unprofitable firms by dividing market cap by total sales. It offers insight into how investors value revenue when earnings are negative.

Q: How does the PEG ratio help investors assess a stock's value relative to its growth?

The PEG ratio factors in the company's growth rate by dividing the P/E ratio by earnings growth. A ratio of 1 indicates fair value, under 1 is cheap, and over 1 is expensive.

Q: Why are high-growth companies likely to have higher P/E and P/S ratios?

Investors expect high-growth firms to expand significantly, leading to inflated ratios. If growth falters, these stocks may experience sharp declines.
