Methodology
The figures use AEP's price data from January 2018 through 2026-10-16.
The entry price is the December 2017 month-end close and the exit is the latest close, both from IEX Historical Data. Price return: adjusted for stock splits, dividends not included. The market comparison uses the TSP C Fund's monthly returns, published at tsp.gov.
Buying at a month-end close misses the highs and lows inside the month, and the figures ignore taxes and fees. To try another amount, month or monthly contribution, use the AEP calculator, which also shows the best and worst entry points in your window.
