Model portfolios have transformed from basic investment templates into versatile, sophisticated tools that support a wide range of advisor and client needs. Today, assets in model portfolios are projected to grow to $11 trillion by 2028, fueled by the rising demand for customization and outcome-oriented investment strategies. 

The most common models remain asset allocation portfolios, especially those built with open architecture, which allows advisors to incorporate both in-house and third-party managers for added diversification and cost efficiency. 

Alongside these, outcome-oriented models—such as those focused on income generation, downside protection, or tax optimization—are gaining popularity for their ability to align with specific client goals. Building block models, which emphasize a particular asset class or investment objective, also offer advisors greater control in tailoring portfolios around their core expertise.
