Understanding Stock Price Change Calculations
Basic stock price change formula:
Price Change=Current Price−Original Price
Example:
If:
- Original price = $50
- Current price = $70
Then:
70−50=20
Stock price increase:
- $20 per share
This formula measures direct price movement.
Understanding Percentage Change
Percentage change formula:
Percentage Change=Original PriceCurrent Price−Original Price×100
Example:
If:
- Original price = $50
- Current price = $70
Then:
5070−50×100=40%
Percentage increase:
- 40%
This helps investors compare investment performance consistently.
Understanding Investment Gains and Losses
Investment gain formula:
Investment Gain=(Current Price−Original Price)\timesShares
Example:
If:
- Price increase = $20
- Shares owned = 100
Then:
20×100=2000
Total gain:
- $2,000
This helps investors estimate portfolio performance accurately.
