What's the rationale offered by NASDAQ for their new "15-days and you're in the index" rule for these massive IPOs? Seems equivalent to removing road safety rules for the least-tested, most-powerful new vehicles only.
They want the index to be representative of the top stocks listed on the Nasdaq, even if they are brand new. The Nasdaq 100 in particular is a marketing tool for the stock exchange, it's not a particularly principled index.
They should just have their own criteria for inclusion in the fund.
