- Popular with young investors (Millenials)

2nd-order effects
- The potential demise of the paid index fund
- Why pay a non-zero management fee, when you can replicate the entire index for free?
- Fidelity has already shown this with zero-fee index funds.
- Higher returns for investors all-else equal
- If you don't change your trading behavior, your returns should rise with this change. You have lower expenses but the same gross return. Your net return should be higher.
- Changing behavior that promotes more frequent trading. (Could be a major negative)
- Changing behavior that increases the number of investors and the amount they invest
- Leading to lower returns in the aggregate as more money chases the same number of assets.
How do brokers make money?
- Robinhood makes money through order flow
- Brokers also earn money through:
- Spread between cash interest paid and earned by the broker to investors
- Internal ETFs and Mutual Funds
- Asset Management Fees
Summary
The end game has begun in the brokerage price wars. We have reached the zero bound in terms of commissions now at $0 for US and Canadian exchanges. This will have a major impact on the accessibility of investing and will certainly change the recommendations I have made in the past to new investors.
