Compare Personal or Private Share Portfolios and Unit Trusts

Private Model Share Portfolios vs Unit Trusts

Choosing between a private share portfolio and a unit trust can be puzzling. Each investment option offers unique benefits and risks. This guide will help you understand the differences when deciding which investment strategy is best for you.
What is a Private Model Share Portfolio?

A share portfolio is a tailored collection of individual stocks that gives investors partial ownership in companies listed on local or international stock exchanges. While primarily focused on equities, it can also include income-generating assets like bonds to improve diversification and stability. The portfolio is designed to align with your specific investment goals and risk appetite.

A model share portfolio is a pre-constructed, professionally designed share portfolio that reflects a specific investment strategy, theme, or risk profile. A well-balanced portfolio spreads risk across different industries and regions. This generally reduces the impact of poor performance in any one area.

At Overberg Asset Management, we pride ourselves on the consistent performance of our model share portfolios—carefully constructed by our investment team and Asset Managers to deliver strong, risk-adjusted returns across market cycles. Each portfolio reflects our deep market insight, disciplined research process, and commitment to helping clients grow their wealth with confidence. Whether you’re seeking growth, income, or diversification, our model portfolios offer a smart, structured path to achieving your financial goals.

What is a Unit Trust?

A unit trust is a type of collective investment scheme where money from multiple investors is pooled together and generally invested in a diversified portfolio of assets—such as shares, bonds, property, or cash.

Each investor owns units in the trust, which represent a proportional share of the total fund. The fund is managed by portfolio managers who make investment decisions on behalf of all unit holders, aiming to meet the fund’s stated objectives (e.g., capital growth, income generation, or capital preservation).

There are over one hundred thousand unit trusts available across markets, and identifying those that are reputable, liquid, and consistently high-performing can be a complex and time-consuming task.

At Overberg Asset Management, we leverage deep market expertise and rigorous research to curate a focused selection of top-tier unit trusts. We essentially save you the effort, time, and choice fatigue when it comes to choosing the correct unit trust.

How to Decide: Key Questions to Ask

What are your financial goals?

Are you looking for long-term growth, income generation, or a combination of both?

How much capital do you have to invest?

  • To access the expertise of a professional asset manager, investors typically need to commit a minimum of R1 million, or the equivalent in foreign currency, into a managed share portfolio. This threshold opens the door to tailored investment strategies and expert oversight, enabling the desired diversification across asset classes, sectors and geographies.
  • Holding a unit trust portfolio valued at R1 million or more, or the equivalent in foreign currency, can enhance diversification compared to investing a smaller amount in a single unit trust. A larger capital base enables broader exposure across multiple asset classes, sectors, and geographies.

Do you want a level of transparency?

  • Model private share portfolios offer enhanced transparency, giving investors access to in-depth information about each individual holding. This allows for closer monitoring and a clearer understanding of how specific assets contribute to overall performance.
  • In contrast, unit trusts provide a more passive investment experience, with unit trust managers providing limited information regarding the underlying investments.
