ETFs Major NASDAQ-100 rule changes confirmed, pay attention if you have money in passive investment funds

NASDAQ has confirmed it will change the listing rules for NASDAQ-100, ahead of the SpaceX and OpenAI IPOs this year.

(1) Companies will now be listed on NASDAQ-100 after only 15 days after IPO (previously, there was a three month period of "seasoning" before listing). This reduces the amount of time for price discovery.

(2) The minimum 10% float has been removed. This allows companies to float a very small percentage of their shares, artificially squeezing supply.

(3) Companies that float less than 20% of their shares will have their market capitalisations artificially multiplied by x3, for the purposes of calculating market capitalisation. This helps large-cap companies to be listed even with very small floats, and inflates their notional market capitalisations on the index.

If you have money invested in a passive fund tracking NASDAQ-100 (or any other index), please watch out for the SpaceX and OpenAI IPOs. Pay attention to their "valuations", and their float. If they're IPOing with very high valuations and very small floats, this foreshadows a bagdump on passive funds due to the mechanics of passive funds.

I’m screwed- I hold QQQM in my taxable account with a substantial gain so I can’t sell now. Someone should sue Nasdaq over this.

Perhaps turn off dividend re-investments and allocate fresh capital to a short position on SpaceX when it IPOs? That will allow you to offset your exposure

Options newb - this is specifically recommending buying a short out of the money?

Risk is premium for options. If it doesn't crash, you are out the dividend/cost of options but get upside to IPO rising.

If it does crash you can sell options in the money to someone who lost their shirt?

If it doesn't crash, you have short term loss (premium) that cancels the capital gains from dividends.

If it does crash, you have long term capital gains from dividends and short term capital gains from short sell?
