估值分析

現時估值

With a P/B ratio of 3.00, this stock is trading above the 科技 sector average of 2.50. This suggests the stock may be 略為高估 based on its book value.

ROE Analysis

The company's Return on Equity (ROE) of 12% is above the sector average. This partially justifies the premium P/B ratio, as companies with higher ROE typically trade at higher multiples.

Tangible Book Value Assessment

The price-to-tangible-book ratio of 3.60 is higher than the standard P/B ratio. This indicates that 16.7% of the book value consists of intangible assets, which may present moderate risk if these assets need to be written down.

未來展望

With projected earnings growth of 8% and a current ROE of 12%, the stock shows reasonable growth potential. Investors should monitor changes in ROE and book value trends in future financial reports.

Understanding Price-to-Book Ratio

The Price-to-Book (P/B) ratio compares a company's market value to its book value. It shows how much investors are willing to pay for each dollar of net assets. This metric is particularly useful for valuing financial institutions, manufacturing companies, and businesses with significant tangible assets.

Types of Book Value

  • Standard Book Value: Total assets minus total liabilities (shareholders' equity)
  • Tangible Book Value: Standard book value minus intangible assets (goodwill, patents, etc.)
  • Book Value Per Share (BVPS): Total shareholders' equity divided by outstanding shares
  • Tangible Book Value Per Share (TBVPS): Tangible book value divided by outstanding shares

Interpreting P/B Values

  • P/B < 1: Stock potentially undervalued, trading below net asset value
  • P/B = 1: Market value equals book value (rare except in distressed situations)
  • P/B > 1: Market values company above its stated net assets
  • High P/B: Often indicates high ROE, strong growth prospects, or understated assets
  • Low P/B: May indicate poor returns, declining business, or overstated assets

P/B Ratio Formulas

Standard P/B Ratio
P/B Ratio = Market Price Per Share ÷ Book Value Per Share
Price-to-Tangible-Book Ratio
PTB Ratio = Market Price Per Share ÷ Tangible Book Value Per Share
ROE-Justified P/B
Justified P/B = ROE × Payout Ratio ÷ (Required Return - Growth Rate)
Book Value Per Share
BVPS = Total Shareholders' Equity ÷ Outstanding Shares

Limitations of P/B Analysis

  • Accounting Practices: Book value can be affected by different accounting methods and policies
  • Asset Composition: Less relevant for service or technology companies with few tangible assets
  • Hidden Assets/Liabilities: May not capture off-balance sheet items or intellectual property value
  • Historical Cost: Assets recorded at historical cost may differ significantly from current market values
  • Sector Variation: P/B ratios vary widely across sectors, making cross-industry comparisons difficult

本工具計算什麼

市賬率——市值相對資產負債表上的淨資產。

公式
市賬率 = 股價 ÷ 每股賬面值
計算示例
股價 120 港元、每股賬面值 80 港元,市賬率為 1.5 倍。
何時使用
最適用於銀行及重資產行業,該類企業的賬面值具實質意義。
常見錯誤
賬面值不計無形資產。軟件公司市賬率 20 倍仍可能便宜,此比率根本無法描述其價值。
