I bought my 1983 Specialized Expedition new in summer 1984 from a local bike shop in Lawrence KS. It retailed for $600 or $650 I think, but Rick sold it to me for around $500-525 if I recall correctly (have the receipt somewhere in a file cabinet).
I could sell it for a bit more than that today I imagine.
If I’d bought the S&P 500 in July 1984, kept it and let dividends reinvest, I’d have returned about 7100%.
I wouldn’t trade any of my bike purchases for such an investment - riding them has been a lot more fun than riding the stock market.
We’ll actually given a re-do I’d swap my 2006 mountain bike purchase for Apple stock, or really anything I purchased in, say, 2009-2013 for bitcoin though.
