What is percentage change?
Percentage change for a stock market is the closing stock market points minus the opening stock market points by the opening stock market points multiplied by 100%
percentage change in stock market=(closing points-opening stock points)/opening points*100%
closing stock market points=120.25( note 1/4=0.25)
opening stock market points=30.50(1/2=0.50)
percentage change in stock market=(120.25-30.50)/30.50*100%
percentage change in stock market=89.75/30.50*100%
percentage change in stock market=2.94262295082*100%
percentage change in stock market=294.26%
