The performance numbers for the POWR Ratings are based on a backtest study conducted in early 2022 that examined stock ratings between January 1, 1999 and December 31, 2021. This backtest bought and sold stocks accordingly once a month on the first trading day after the Saturday ranking.
Data and performance returns shown are for illustrative purposes only. Though we have made an effort to closely match performance results shown to that of portfolios over time, these results are entirely the product of computer models.
Actual individual investor performance has and will vary depending on the time of the initial investment, amount and frequency of contributions, intraperiod allocation changes, taxes and other factors. Additionally, this study illustrates past performance, but is not and cannot be indicative of future results.
Our simulation protocol assumes all trades occur on a Monday (or if the market is closed on a particular Monday, then the first trading day of the week) and that they are accomplished in a single lot that is priced at the average of the high and low for that day.
We do not take trading costs into account.
Splits are applied on the dates that they became active. All numbers presented are as of the date of the last available pricing data. For example, if a stock split in January 2015 and then left the database in July 2017, and you look at a transaction that would have taken place in September 2014, it will be expressed in July 2017 terms.
We apply stock dividends the same way that we apply splits, except that we differentiate between the ex-dividend date and the payment date. If a stock is owned on the ex-dividend date then it will have the price adjustment applied. If not, then the stock will be priced as appropriate thereafter.
