This asset allocation ETF tracks the ProCap Index. It holds both equity ETFs and bond ETFs and follows a rules-based strategy that adjusts weights as the economic regime changes. Most of its assets are invested in the ETFs that make up the index.

It suits investors who want to diversify across stocks and bonds in a single product and delegate the asset allocation decision.

It is a passive (index-tracking) ETF managed by Monarch.

The ProCap Index consists of a small number of equity ETFs and bond ETFs, and rules cap the weights so that these two asset classes make up most of the index. By adjusting the asset class allocation according to rules based on economic data, it builds a diversified asset allocation portfolio within a single product.

• Asset allocation structure holding both equity and bond ETFs
• Asset class weights adjusted on a rules basis

Assets under management (AUM) stand at $252.7M, and the total expense ratio is 1.03% per year.

Its fund-of-funds structure bundles several ETFs into one, allowing investors to hold a diversified portfolio without assembling individual assets themselves.

Because it holds both stocks and bonds, its volatility tends to be milder than that of a pure equity fund, and its returns are affected by both equity and bond market trends as well as the interest rate environment. Recent trends also vary with the relative strength of the two asset classes.

Asset allocation products see capital flows driven by demand for volatility management, and money seeking diversification benefits sometimes flows in when market uncertainty rises. Fund flows shift with the relative appeal of the stock and bond markets.

Its strength is delivering diversified asset allocation in a single product, but a weakness is that, given the nature of asset allocation products, its fees tend to be higher than those of a simple index fund.

Similar asset allocation alternatives include the Core Allocation series managed by iShares. The series is divided by risk profile: the equity-heavy aggressive AOA, the balanced AOR, the moderate AOM and the conservative AOK, so investors can choose their own stock and bond mix. For income-focused asset allocation, the distribution-oriented HNDL is also worth comparing.

Here are the points to review before investing in MPRO. Because asset allocation ETFs have a different cost structure from simple index funds, it is wise to check the fee level, the stock and bond weights, and interest rate sensitivity in advance.

Holding both stocks and bonds may keep volatility mild, but risk does not disappear, and in a rising rate environment the bond allocation can generate losses. The cost burden of the asset allocation structure also affects long-term performance.

It is a suitable choice for investors who want to delegate diversified asset allocation to a single product. If you would rather choose the asset class weights yourself, we recommend also comparing the iShares Core Allocation series, which is divided by risk profile.
