Phrasing of Capitalization-weighting

There's been a back-and-forth over how to phrase the transition from weighting the index by all shares vs. weighting by publicly available shares (see e.g. this diff). I support the IP's removal of the phrase. The two linked articles, Market capitalization & Capitalization-weighted index are both described using the same language in the articles ("the share price multiplied by the number of shares outstanding" & "the total market value of their outstanding shares"). The Capitalization-weighted index does have a note of what we're really discussing here: float-weighting, but the contentious sentence says the index is moving away from cap-weighted, moving towards the market-cap page that doesn't discuss float-weighted at all. I think the preceding sentences establish what the transition is, and linking to these terms is unhelpful at best, and misleading at worst. I would support either using the IP's version or linking to Public float somehow, though I don't see a natural-language way to do it. OwenX, do you have a case to make for market cap?

Edit: how about this wording? MarginalCost (talk) 16:32, 3 August 2018 (UTC)

MarginalCost, I don't have a dog in this race. My issue was with the phrasing, not the content. Starting a sentence with "This transformation [...]" without making it clear which transformation we're talking about was simply poor writing. I didn't check the sources for your edit, but at least your phrasing is coherent. Thanks! Owen× ☎ 13:59, 5 August 2018 (UTC)
