Multi-asset investing has long been a popular form for building a client's portfolio, as it take out the challenge of selecting the right, complementary assets.

But now many clients are asking for sustainable investments, and this poses an additional layer of complexity for fund managers.

A typical way of building a multi-asset fund is to invest in a diverse range of asset classes, but now some of these may not conform to the client's demands for sustainability.

For example, a typical diversifier could be government bonds, but some people might disagree with the policies of governments, so these may mean they would have to be excluded.

Similarly the types of equities a fund manager might choose will likely be different to stocks they may have invested in for a conventional portfolio.

Nonetheless, both sustainability and multi-asset are two areas highly favoured by investors now, so it is worth advisers taking the time to understand how these two trends interact.
