How the P/E ratio is calculated?
The price-to-earnings ratio for the index is calculated by dividing the total market capitalization of all index companies by the sum of trailing 12-month net income of the companies. Also companies with negative trailing earnings are included in the calculation. This means that the P/E calculated by us is higher than for example the P/E ratio that iShares (BlackRock) is publishing for their CNDX NASDAQ 100 ETF. We believe that our calculating method provides a better view of the current index valuation than just calculating the average of P/E ratio of the individual index companies.
