Nonsense.

The extremely small float of these offerings will make index weights a rounding error.

Ask your LLM of choice to compare the likely value of shares to be held by index funds with the market cap of each of these companies.

I don’t understand the argument that small amounts don’t matter.

Diversification doesn’t work if you throw in low quality investments you wouldn’t consider on their own. It just lowers returns.

except that they changed the index rules to OVERweight them because of their small float.
