So far only Nasdaq has changed its rules and will allow fast entry in 15 trading days. S&P has not changed its rules, not yet at least. Total indexed capital of Nasdaq is 1.4T vs 16T in the S&P500. Stated reason for fast tracking is that the indices are supposed to be a broad representation of the market, and leaving a 2T company out would be a significant tracking error.

I do agree that the optics of this aren’t great, and it’s rather easy to be cynical about motives.

I did a bit of research on this some time ago and it's not as bad as I originally thought. Index funds would need to count only liquid float of the company. So if Space X total valuation is 2 trillion, but float is 5%, then they need to count it as 100 billion for the purposes of index weight. Still more than I want, but not catastrophic.

Oh yes, thanks for reminding me. I’m going to cash out the 401(k).

What are you basing this on?

I'm not an expert but it looks to my like 80% of my allocation won't be tracking spacex, because it's mid cap or small cap etc, and the 20% that's in the vanguard growth index might? I assume whoever sets the rules for the fund could change the rules to say companies must be listed for X months if they want to avoid this, right?

And I can change my allocation.

edit: Actually wait, isn't it only nasdaq 100 that's tracking it early, after 15 days rather than 3 months of trading? So 0% of my 401k is exposed to buying it quickly after IPO already, I think.

So far they're only getting fastracked into Nasdaq 100, not S&P 500.

The question is, is everyone integrating a special SpaceX correction in their algorithmic trading? Because if a dip in the index due to SpaceX causes old algorithms to think it’s a more structural issue (well, more than it is), and sell on that indicator, will that cause a cascade?

If your retirement fund is an IRA you can invest it in any stock you want. For a 401k you probably have some fund options that are not exposed to the S&P500, like emerging markets or fixed income

Maybe this already exists, but it would be great if one of the major index ETFs omitted all the firms with problematic board governance like there is at Tesla, SpaceX.

My money's all in Bitcoin pats himself on the back

401k rollovers into IRA aren't that hard these days and you could always use that IRA to have a more customized strategy, more specifically direct indexing of a major fund minus key ticker symbols you don't want exposure to. Of course, that all presumes that you won't regret excluding this long term.
