The data item is a percentile ranking (ranking between 0 -100) of the stock, against all other stocks in the country, based on recent historical price performance. The rank is calculated taking into consideration the price movement of the stock over the previous 12 months as well as the strength of price movement compared to its industry peers

As discussed earlier, price momentum is the rate of change in the price of a particular stock. Momentum traders and investors believe that stocks that have trended up over the previous 3-12 months will continue to move up faster than the market over the next 3-12 month period. Hence buying stocks with higher price momentum might increase the possibility of earning higher price returns

Higher the price momentum rank, stronger the price momentum. So if the overall score is 97, it indicates that the security has better price momentum than 97% of the stocks
