I just wrote a post on how my calculation of their 2013 performance is far different from their calculation.
Writing that post prompted me to check up on some other numbers posted on the Gone Fishin’ Portfolio website. Here is a chart where they supposedly show how much better they would have done than the S&P 500 over the last 10 years. I am assuming this chart ends at the end of 2013.
These numbers didn’t look quite right to me, given my understanding of the performance of the Gone Fishin’ Portfolio and the S&P 500 over the last 10 years. You are probably thinking my next step was to look at the performance of the Gone Fishin’ Portfolio over the last 10 years and see if it matches up with what they have, right?
Nope. I decided to simply look at the performance of the S&P 500 over the last 10 years and see if it matches up with what they have. They should at least have correct numbers on the S&P 500.
And…..it doesn’t. What the heck. Where are they getting their numbers and data?
They show a $100,000 investment in the S&P 500 (with dividends reinvested) growing to 240,353 over 10 years.
That’s not what I get using the S&P 500 total return (dividends reinvested) index as reported by Morningstar. I get $100,000 grows to $204,300 for the 10 years from 1/1/2004 to 12/31/2013.
Below is a link to the chart showing $10,000 would grow to $20,430 – so just add an extra zero to figure it out with $100,000.
I seriously have no clue where the Gone Fishin’ Portfolio people get any of their numbers .
