> I was planning to move to an equal weight index but this gives me a little more time to evaluate options.

S&P requires 4 consecutive profitable quarters, amongst other requirements, so if one of the new mega caps like SpaceX or Anthropic or OpenAI get included, you’d probably want to get the benefit of their performance.

Put differently, if one previously specifically picked an index fund that is not equal weighted, why would you change from that strategy?

Many people already have x% of their portfolio allocated to a growth fund, that might include fast growing AI companies. You need to keep the risk profile consistent. If you change the rules you mess up people's strategy.

But they haven't been good performers, and don't deserve joining s&p, and that is the point, do not make exceptions just because Elon Musk or whatever delusional billionaire says so.
