Mid and Small Cap ETFs: Which is Cheapest?

Well, another one of these wonderful stories of cost with a Vanguard fund. You've got a clear winner out of the gates. BXF charges four basis points as a completion vehicle. IWM is the liquidity king.

If you want to do large institutional trades, there's no question it has better spreads, but VXF is still tight, very low spread at three basis points. Whereas IWM is pretty much free to trade in terms of the spread.

But the expense ratio being a 15 basis point difference from a buy and hold perspective, it's a pretty clear winner for VXF.
