估值分析

现时估值

With a P/E ratio of 26.09, this stock is trading above the sector average of 24.5. This suggests the stock may be 略为高估 compared to sector peers.

Growth Perspective

The PEG ratio of 2.61 indicates the stock is trading at a premium relative to its growth rate. A PEG ratio above 1.0 generally suggests that earnings growth is not keeping pace with the valuation.

Earnings Yield Analysis

The current earnings yield of 3.83% is slightly above the risk-free rate of 3.5%. This indicates a minimal equity risk premium, which may not adequately compensate for the additional risk of equity investment.

Forward Outlook

Based on the projected earnings growth of 10%, the stock's forward P/E of 23.72 suggests moderate potential for price appreciation. Investors should monitor earnings results against these growth expectations.

Understanding P/E Ratio Analysis

The Price-to-Earnings (P/E) ratio is one of the most widely used valuation metrics in financial markets. It compares a company's share price to its earnings per share, indicating how much investors are willing to pay for each dollar of earnings.

Types of P/E Ratios

  • Trailing P/E: Based on earnings from the past 12 months
  • Forward P/E: Based on projected earnings for the next 12 months
  • Normalized P/E: Adjusts for economic cycles by using average earnings over multiple years
  • PEG Ratio: P/E ratio divided by earnings growth rate, providing context to the P/E

Interpreting P/E Values

  • High P/E: May indicate overvaluation or expectations of strong future growth
  • Low P/E: Could suggest undervaluation or concerns about future performance
  • Negative P/E: Indicates the company is losing money (negative earnings)
  • Industry Comparison: P/E should be compared with industry peers for context
  • Historical Context: Compare current P/E to the company's historical average

P/E Ratio Formulas

Basic P/E Ratio
P/E Ratio = Current Share Price ÷ Earnings Per Share (EPS)
PEG Ratio
PEG Ratio = P/E Ratio ÷ Annual EPS Growth Rate
Earnings Yield
Earnings Yield = EPS ÷ Share Price = 1 ÷ P/E Ratio
Justified P/E (Gordon Growth Model)
Justified P/E = (1 - Dividend Payout Ratio × (1 + g)) ÷ (r - g) where g = growth rate, r = required rate of return

Limitations of P/E Analysis

  • Accounting Differences: Variations in accounting practices can affect earnings figures
  • Cyclical Businesses: P/E can be misleading for businesses with cyclical earnings
  • Growth Not Considered: Basic P/E doesn't account for growth rates (PEG ratio addresses this)
  • Negative Earnings: P/E cannot be calculated for companies with losses
  • Interest Rate Environment: P/E ratios tend to be higher when interest rates are low

本工具计算什么

市盈率——市场为每单位盈利所付出的价格。

公式
市盈率 = 股价 ÷ 每股盈利
计算示例
股价 120 港元、每股盈利 8 港元，市盈率为 15 倍。
何时使用
将公司与自身历史或同业比较。
常见错误
脱离脉络的市盈率毫无意义。偏低往往反映市场预期盈利下滑，而非便宜；盈利为负时更完全失效。
