Frequently Asked Questions
Does past stock performance guarantee future returns?
No, past performance is not a guarantee or reliable indicator of future results. Stock markets are inherently unpredictable, and historical returns reflect unique economic conditions that may not repeat. This tool is for educational and entertainment purposes only, not investment advice.
How are historical investment returns calculated?
The calculator retrieves the actual closing price of a stock on the start date, calculates how many shares your investment would have purchased at that price, and multiplies by the current price to determine today's hypothetical value. Dividends and stock splits are not factored into the calculation.
What is the average annual stock market return?
The S&P 500 has historically returned approximately 10% per year on average before inflation, or about 7% after inflation, over long periods. However, individual years can vary dramatically, with some years seeing gains of 30%+ and others showing losses of 30% or more.
Which stocks have been the best long-term investments?
Companies like Apple, Microsoft, Amazon, and NVIDIA have delivered exceptional returns over the past decade. However, top performers change over time and picking individual winners in advance is extremely difficult. Diversified index funds have historically been the most reliable path to strong long-term returns.
Why does time in the market matter more than timing the market?
Missing just the 10 best trading days over a 20-year period can cut your returns in half. Since the best days often occur near the worst days during periods of volatility, staying invested through downturns is crucial. Consistent long-term investing outperforms attempts to buy low and sell high for the vast majority of investors.
How the “If You Invested” Calculator Works
The Market Informative “If You Invested” tool uses real historical stock prices to calculate hypothetical investment returns. Enter any publicly traded stock ticker, the dollar amount you would have invested, and a time period of 1, 3, 5, or 10 years. The calculator retrieves the actual closing price on your start date, determines how many shares your investment would have purchased, and multiplies by today's price to show your hypothetical portfolio value. The growth trajectory chart visualizes the stock's price movement over the chosen period.
