The universe of passive funds or ETFs includes those that track specific industry/sector, size, region and other factors. Even if the whole market is passive, traders could still vote on the valuation of an asset by buying/selling

Further suppose that interactions of interest are half the size of main effects. Why make this assumption? I'm hoping to see more justification as to why the main effect should be assumed to be exactly 2x the interaction effect. Edit

You pay an extra quarter percent to 1) not have to think about allocation and risk under-diversfication, and 2) commit to the "buy and hold" strategy since its withdrawal process is more cumbersome than normal trading. I think for

Robinhood is the only one among the new batch of fintech startups that encourages active trading. Their entire UI is built to optimize for ease of trade rather than thinking in terms of portfolio objective and diversification. Contrast
