Several things to consider. Three very important ones that must be considered in any financial comparison (some have already been mentioned, just trying to consolidate it here).
A) As has been pointed out, it must be apples-apples. Your figures for DOW are not total return, only the price change. This understates the DOW, it just pretends there are no dividends paid, they just vanished! That is disingenuous, to be polite (not criticizing you, just the source you used).
Please, compare total value, or it is meaningless!
B) Cherry picked time frame. 2001 was near the peak of the fixed interest rate for iBonds. I'll guess they didn't select the actual peak, as it may have made stocks look better? Why 2001? It's not 20 years, it's not, well, anything, which makes it sound cherry picked.
See this page, can't seem to copy the image.
I-Bonds: Current I-bond Fixed Rate
And iBonds paid ~ 3.00% fixed in 2001. For the past 10 years, the fixed rate has mostly been
zero, 0%, nada, nothing, niente, nichts! The rate is dead I tell you (Monty Python reference)! A few periods of 0.1% ~ 0.3% in there, and recently rising to 0.5%.
C) An investor today can't replicate this. Other than an interesting historical view, it's about the same as saying "$10,000 invested in AAPL JAN2001 would be worth, wait for it... $1,773,822 today". Even after inflation, that's $1,164,305! Take
that, you stinkin' iBonds!
Yes, iBonds turned out to be a good deal when they paid 3% fixed. I should have jumped in, But with a $30,000 annual limit, it would not have been that big a deal overall.
Thanks for the interesting bit of history, but that's about all it is. Wake me up if iBonds hit 3% again!
