We use fractional shares. But otherwise you are correct, our minimums are set to allow you to buy at least $5 of each member of the US 500.

We do not charge trade commissions. There are some SEC fees charged for trading across most major brokerages. The national best bid offer (NBBO) means you will get executed at the current best price for a given security across all exchanges.

Thanks, regarding transaction fees, I was referring to slippage (should have said transaction cost). This depends a lot on your customers rebalancing settings, but it would be good to be able to compare that directly to VOO.

Yeah it's an interesting point. Due to the redemption mechanism of ETFs, my understanding is that an ETF's bid-ask spread is basically the weighted average of the bid ask spread of it's underlying holdings. Which to answer your questions means that buying the individual stocks within an ETF would result in approximately the same slippage as buying the ETF itself.

This is definitely not true in practice except for maybe highly liquid ETFs and underliers
