Understanding Percentage Moves

Why Track Percentage Change?

Raw dollar amounts can be deceiving when trading assets of vastly different prices. A $5 move in a $10 stock is a massive 50% gain, while a $5 move in a $1,000 stock is a negligible 0.5% fluctuation. Professional traders normalize their analysis by thinking purely in percentages. This allows for fair comparisons between different trades, instruments, and asset classes.

The Mathematical Formulas

To calculate a future target price based on a desired percentage gain:

To calculate the percentage change between your entry and the current price:

Practical Trading Scenario

You are trading a cryptocurrency that you purchased at $3,450. You want to place a limit sell order exactly 15% above your entry price to lock in profit. By plugging $3,450 and 15% into the calculator, you instantly find your target price is $3,967.50. You place your limit order and step away from the screens.

Alternatively, if you bought a stock at $120 and it is currently trading at $138, you can use the second calculator to determine that you are currently up 15% on your position.
