How percentage is calculated

The Change value is the difference between the latest price on the symbol and the previous period's closing price.

Percent Change, meanwhile, is calculated by dividing the Change value by the previous period's close and multiplying the result by 100.

Percent Change Calculation:

Daily Chg = (Price - Prev Day's Close) / Prev Day's Close * 100
Weekly Chg = (Price - Prev Week's Close) / Prev Week's Close * 100
Monthly Chg = (Price - Prev Month's Close) / Prev Month's Close * 100
