In the world of equity investing and financial analysis, it’s essential to interpret historical stock data accurately. One often overlooked component is the adjusted share price, which accounts for corporate actions like stock splits, bonus issues, and rights offerings.
These events affect the number of outstanding shares and the share price but do not alter the company’s intrinsic value. Adjusting the share price helps investors and analysts make apples-to-apples comparisons across time periods.
This article dives deep into the Adjusted Share Price Calculator, a handy tool to recalculate the true value of shares after corporate adjustments.
Formula
The adjusted share price can be calculated using the following considerations:
- For Bonus Shares
Adjusted Price = Original Price ÷ (1 + Bonus Ratio) - For Stock Splits
Adjusted Price = Original Price ÷ Split Ratio - For Rights Issue with Discount
Adjusted Price = Adjusted Price × (1 – Rights Discount%)
Combining all adjustments:
Adjusted Share Price = (Original Price ÷ (1 + Bonus Ratio) ÷ Stock Split Ratio) × (1 − Rights Discount%)
Note: Adjustments are applied sequentially.
How to Use
To use the calculator:
- Original Share Price: Enter the price before any corporate action.
- Bonus Ratio: Input as a decimal. For 1:1 bonus, enter 1; for 1:2, enter 0.5.
- Stock Split Ratio: For a 2-for-1 split, input 2. For no split, use 1.
- Rights Issue Discount (%): Enter the discount percentage on new rights shares, if applicable.
- Click “Calculate” and view your adjusted price below.
Example
Scenario:
A company’s original share price is $120.
- They declare a 1:1 bonus share (Bonus Ratio = 1).
- They announce a 2-for-1 stock split (Split Ratio = 2).
- Then offer a rights issue at 20% discount (Rights Issue Discount = 20).
Step 1: Adjust for bonus
120 ÷ (1 + 1) = 60
Step 2: Adjust for stock split
60 ÷ 2 = 30
Step 3: Apply rights issue discount
30 × (1 – 0.20) = 24
Adjusted Share Price = $24
