To calculate ROC, you divide the current price by an earlier price, then, to convert it to a percentage, subtract 1 from that value and multiply by 100: ROC = [ (Current Price / Earlier Price) - 1] *100. For example, the current price could be divided by the closing price six months ago to find the 6-month ROC. lighting screenedporch
