Introduction – Why Mid Caps?
Mid-cap stocks are often referred to as the “forgotten size segment” or the “orphaned index,” due to the fact that large-caps and small-caps get all the press. Many investors tilt large-cap or small-cap, altogether ignoring or forgetting about mid-caps, or simply relegating them to their limited exposure in a total market index fund.
Small-cap stocks are usually companies in their early stages of growth. Large-caps are well-established, “stable” companies. Mid-caps, of course, are somewhere in the middle. Investors assume that mid-cap stocks carry more risk and return than small-caps, and less risk and return than large-caps, and understandably so, as this is how the Size factor premium should play out on paper. Returns going back to 1972 tell a slightly different story:
At least for the period 1972 through July 2020, mid-caps as a whole have achieved higher general and risk-adjusted returns than small-caps, with lower volatility.
So now that we know mid-caps are probably a solid investment, let's explore the 5 best mid cap ETFs.

The 5 Best Mid Cap ETFs
Below are the 5 best mid cap ETFs from various providers:
VO – Vanguard Mid-Cap ETF
The Vanguard Mid-Cap ETF (VO) is one of the most popular ETFs for the mid cap market segment. The fund has over $60 billion in assets and a low expense ratio of 0.04%. This ETF gets you broad exposure to the mid-cap range of stocks with over 350 holdings, and seeks to track the CRSP US Mid Cap Index.
It's worth noting that VO has a much higher weighted average market cap than the other funds on this list, so it arguably skews large cap. This may or may not be desirable. Those seeking true mid caps should probably prefer a different fund.
IWR – iShares Russell Mid-Cap ETF
Those seeking broader exposure to US mid caps will enjoy the fact that IWR from iShares has over 800 holdings via the Russell MidCap Index, which is composed of the 800 smallest stocks in the Russell 1000 Index. As a result, just like VO, IWR ventures a bit into large cap territory with a weighted average market cap of about $25 billion.
IWR has about $35 billion in assets but is more expensive than other funds on this list with a fee of 0.19%.
SCHM – Schwab US Mid-Cap ETF
The Schwab US Mid-Cap ETF (SCHM) is another great low-fee option for investing in mid-cap stocks. This ETF tracks the Dow Jones U.S. Mid-Cap Total Stock Market Index, putting it squarely between small caps and large caps. SCHM has about 500 holdings and has an expense ratio of just 0.04%.
IJH – iShares Core S&P Mid-Cap ETF
The iShares Core S&P Mid-Cap ETF (IJH), as the name suggests, seeks to track the S&P MidCap 400 Index. IJH is the most popular fund out there for the US mid cap segment, and for good reason. Its S&P index conveniently screens for earnings, providing positive loading on the Profitability factor.
The fund has over $88 billion in assets, 400 holdings, and an expense ratio of 0.05%.
SPMD – SPDR Portfolio S&P 400 Mid Cap ETF
SPMD from SPDR seeks to track the same index as IJH but now at a slightly lower fee of 0.03%, which conveniently makes it the cheapest on this list. In my opinion, it also happens to provide the best exposure to US mid caps, so it would be my choice. SPMD has over $10 billion in assets.
International Mid Caps?
It's worth noting that U.S. investors wanting exposure international mid caps have basically zero options aside from a pretty pricey dividend fund from WisdomTree, which is DIM with a fee of 0.58% and a pretty low AUM of only a little over $100 million. For that reason, I would either move down to international small caps, for which more options exist, or simply target both small caps and large caps (or the total stock market) internationally.

What made you go long VOE as opposed to say VO or VOT.? Value or growth / blend?
Sorry, just didn’t update this. I no longer own VOE. But I do tilt Value based on what I laid out here on factors.
Hi John,
You made a really compelling argument at the top of this article for owning mid-cap stocks. I’ve been playing around with some back-testing of mid-caps and surprisingly owning a single mid-cap fund would provide greater returns than a 50/50 split fund of Large-cap and small-cap value and they would do so at similar volatility. They seem to weather any economic conditions fairly well. I also prefer to tilt towards value stocks but when I saw how well a simple mid-cap blend fund could do and with such resiliency I couldn’t believe my eyes! Did you exclude them from your portfolio for any particular reason? As always, thank you for sharing,
— David
Your backtest probably didn’t go back far enough, and we’d probably want to avoid small cap growth stocks. I explained that and my incidental exclusion of mid-caps here.
True, I only back tested to 1981. When I run it again to include the 70’s small-cap value does so well it doesn’t take much of it to totally smokes all other cap sizes.
I went with IJH. No overlap with VOO. VOE has a lot of overlap with VOO.
