Stock Weight Calculator

Investors and financial analysts often use stock weight calculations to understand the proportion of an individual stock within the total portfolio. This metric is essential for portfolio management, risk assessment, and investment strategy.

Historical Background

The concept of stock weight in a portfolio has been a fundamental aspect of investment theory, evolving with the development of portfolio management practices. It reflects the investor's exposure to specific securities relative to the total investment portfolio.

Calculation Formula

The stock weight is calculated using the formula:

\[ SW = \frac{SV}{PV} \times 100 \]

where:

• \(SW\) is the Stock Weight (%),
• \(SV\) is the total stock value ($),
• \(PV\) is the total portfolio value ($).

Example Calculation

If an investor has $15,000 invested in a particular stock and the total portfolio value is $150,000, the stock weight can be calculated as:

\[ SW = \frac{15000}{150000} \times 100 = 10\% \]

Importance and Usage Scenarios

Stock weight is crucial for managing a diversified portfolio. It helps investors make informed decisions on buying, holding, or selling stocks based on their target allocation and risk tolerance. Portfolio rebalancing often involves adjusting stock weights to align with strategic investment goals.

Common FAQs
