How to Use the Good Stock Calculator
Using the calculator is simple. You’ll need to gather some basic financial data of the stock you're analyzing. Here’s a step-by-step process:
Input Required:
- Current Stock Price – The current market value of one share.
- Earnings Per Share (EPS) – The portion of a company’s profit allocated to each outstanding share.
- Expected Growth Rate (%) – The anticipated rate of growth in earnings.
- Industry Average PE Ratio – The average price-to-earnings ratio for the sector the company belongs to.
- Your Desired Rate of Return (%) – Your target investment return.
Output Provided:
- Estimated Future EPS
- Estimated Future Price
- Intrinsic Value
- Investment Decision (Buy, Hold, Sell)
Formula Used in the Good Stock Calculator
To determine if a stock is “good,” the calculator relies on the following steps and formulas:
- Estimated Future EPS:
Future EPS = Current EPS × (1 + Growth Rate)^n- Where
n= number of years (commonly 5 or 10 years)
- Estimated Future Price:
Future Price = Future EPS × Industry PE Ratio
- Intrinsic Value (Discounted Price):
Intrinsic Value = Future Price / (1 + Desired Return)^n
- Investment Decision:
- If Intrinsic Value > Current Price → Stock is undervalued (Good Buy)
- If Intrinsic Value < Current Price → Stock is overvalued (Avoid or Sell)
Example Calculation
Let’s assume the following values:
- Current Stock Price: $50
- EPS: $2
- Expected Growth Rate: 10% per year
- Industry PE Ratio: 20
- Desired Return: 12%
- Time Frame (n): 5 years
Step 1: Estimate Future EPS
Future EPS = 2 × (1 + 0.10)^5 = 2 × 1.61051 = 3.22102
Step 2: Estimate Future Price
Future Price = 3.22102 × 20 = $64.42
Step 3: Calculate Intrinsic Value
Intrinsic Value = 64.42 / (1 + 0.12)^5 = 64.42 / 1.76234 = $36.56
Step 4: Investment Decision
Since $36.56 (Intrinsic Value) < $50 (Current Price), the stock is considered overvalued. You may want to avoid or wait for a price drop.
