a bit out of date, missing at least one global financial crisis, but there's a 2004 paper looking at the returns of holding the original S&P500 companies from its start 65 years ago, with some alternative portfolios too.

Some of the particular decisions in the setup may or may not agree with grandpappy, I only skimmed, but it looks like the "survivor's portfolio" has returns in line with S&P500-with-replacement and even outperformed the newcomers slightly.

19 of the largest 20 companies were still around in some form when including mergers and acquisitions... however again this is 2004, and at least Kodak and Sears went out of business since then, IIRC?

Far stranger than going out of business, KODK became a meme stonk when Trump announced they were going to manufacture hydroxychloroquine causing it to 10X overnight back in early 2020. [1]
