About this fund

Somewhere in the middle of U.S. markets

What is the S&P 400 Mid-Cap?

This fund gives investors exposure to medium sized companies — known as mid-caps — that potentially offer a balance between growth potential and stability. In this fund, companies with a total share value of between $8 billion to $22 billion are included, but these parameters may vary based on the methodology of the underlying index. 

Investing in this fund gives diverse exposure to four hundred mid-cap U.S. companies, in one passive investment.

Sector exposure

This fund’s underlying index ranks companies based on total market value within the parameters of S&P’s mid-cap market value ($8—22 billion). It includes a mix of sectors, with current leading exposure in industrials, financials, consumer goods, tech, and healthcare. These sector weightings can shift over time as the index moves.

Index Tracker

This is a passive index fund, meaning it does not aim to outperform the market or pick individual winners. Instead, it tracks the S&P 400 MidCap Index, which reflects the performance of mid-cap companies in the United States. 

Because of its index-tracking structure, it’s low cost and automatically updated to reflect changes in the underlying index.

S&P 400 Mid-Cap FAQ's

Is this different to the S&P 500?

Yes — while the S&P 500 tracks the largest five hundred companies by market capitalisation (total share value), this fund tracks an index of the four hundred largest companies by market capitalisation, within the parameters of mid-cap market value (in this instance companies with a total share value of between $8 and $22 billion).

Does this fund pay dividends?

No – this fund accumulates returns, meaning they are automatically reinvested back into the fund. This style of investing could be better for investors seeking growth — rather than income — from their investment.

Why would I buy a fund over individual stocks?

This fund gives you access to four hundred companies in one investment. By investing in an index fund rather than the shares within the index, you’ll cut down on risk, effort, and most likely costs too.

Are mid-cap stocks a good investment?

Mid-cap stocks can help further diversify your portfolio, and potentially reduce volatility in certain economic conditions. Historically, mid-caps have relatively low correlation with large-cap stocks.
