INVESTOPEDIA EXPLAINS 'Decile'
When an analyst or statistician ranks data and then splits them into deciles, it is in an attempt to discover the largest and smallest values by a given metric. For example, by splitting the entire S&P 500 Index into deciles (50 firms will be in each decile) by the P/E multiple, the analyst will discover the companies with the highest and lowest P/E valuations in the index.
