Video Overview
This short video opens a series on annualized returns and explains the compound-growth calculation without requiring viewers to memorize a complex formula. The speaker starts with 100 units of capital growing to 250 over ten years. Ending value is divided by starting value to obtain the total multiple, the natural logarithm is divided by the number of years, and the exponential function converts the result back into an annual compound rate. The same method is then applied to QQQ for a period from a 2009 low to 2019 and for a holding period that began near a 2007 high. These examples show how the purchase date and investment horizon alter the annualized result. Prices, dividends, and returns are historical figures used in the video; the lesson concerns the calculation method rather than future performance.
Key Takeaways
- Annualized return converts the total growth achieved over a multi-year period into the constant compound rate that would produce the same ending value each year.
- The calculation divides ending value by starting capital, takes the natural logarithm, divides by the number of years, and then applies the exponential function.
- In the teaching example where 100 grows to 250 over ten years, the video calculates an annualized return of approximately 9.59 percent.
- The QQQ examples compare starting near a 2009 low with starting near a 2007 high, showing that the entry point and the length of the holding period both affect the result.
Chapters
About 00:00:00 · Annualized Return and Compound Growth
The opening introduces a series that will evaluate SPY and QQQ with annualized returns and begins by establishing the basic calculation method.
About 00:01:20 · Calculating Growth from 100 to 250
The video works through the total multiple, natural logarithm, division by years, and exponential function to obtain an annual compound rate.
About 00:03:45 · QQQ from a Ten-Year Low and a Prior High
The speaker applies the formula to two QQQ starting points and adjusts the holding years before comparing the annualized figures shown in the video.
About 00:06:40 · Reviewing the Formula
The ending repeats the sequence: divide ending value by principal, take the logarithm, divide by the number of years, and then apply the exponential function.
