What is robo investing? 

Robo investing, also known as robo advising, is a digital investment service that uses algorithms to manage portfolios, typically based on your risk tolerance.

Instead of a human financial advisor, robo advisors automate investment decisions and portfolio management, offering a convenient and often lower-cost alternative.

How do robo advisors work?

Here's a more detailed breakdown of how robo-advisors work:

1. Gather information

You'll complete a questionnaire providing details about your financial situation, investment goals (e.g., retirement, home purchase), and risk tolerance.


2. Create a portfolio

Based on your answers, the robo advisor's algorithms will suggest an appropriate investment portfolio, often consisting of a mix of ETFs and mutual funds.


3. Make investments

The robo advisor will automatically invest your money according to the recommended portfolio.


4. Monitoring and rebalancing

The robo advisor continuously monitors your portfolio and will automatically rebalance it to maintain your desired asset allocation as market conditions change.


5. Fee structure

Robo advisors typically charge a fee, usually a percentage of your assets under management, for their services.

What are pros and cons of robo investing?

Pros 

  • Cost-effective compared to traditional financial advisors 

  • Tailored investment strategies based on your risk tolerance 

  • Time-saving as the robo advisor takes on the work of selecting and reassessing the funds 

  • Investment growth can be tax-free if used as part of your ISA allowance 

  • Some platforms offer the ability to block certain sectors that don't match an investor's ethics 

Cons 

  • Platform fees may impact overall returns 

  • Investments can decrease in value 

  • The robo advisor's chosen funds may not always match your personal ethics, though some platforms offer exclusions 

How do I choose the best robo advisor account?

 When selecting a robo advisor, consider the following:  

  • Account type: Ensure it aligns with your investment goals and risk appetite 

  • Costs: Weigh platform fees against fund management expenses 

  • Additional features: Look out for perks like cashback or automatic rebalancing 

  • Customer support: Make sure you're comfortable with the level of support and the online system, and happy with customer support 

What should I consider before using a robo advisor?

Before you commit, keep in mind:  

  • Be mindful of platform fees 

  • Be comfortable with a robo advisor taking the investment reins 

  • Be prepared for a long-term investment to allow for growth 

  • Ensure you are comfortable with the platform fees and the long-term nature of the investment 

  • Consider if you are comfortable with a robo advisor making investment decisions on your behalf 

Robo advisor vs manual investing - which is better?

It all depends on your personal preference and how you choose to invest.

Robo-advisors typically charge lower fees than traditional financial advisors. There also isn't any need for regular manual reviews; the robo advisor adjusts the portfolio automatically.

On the other hand, manual investing offers greater control and choice, allowing for a more hands-on approach if that's what you prefer.  

Choosing a robo advisor investment account  

For those new to investing, we suggest starting with a robo advisor. It's a great way to dip your toes in the water and gradually build your investments, as MoneySuperMarket partners with leading robo investment platforms, offering a wide range of choices for UK investors.   

The platform lays out essential information, such as platform fees and minimum investments, making the application process straightforward and quick.  

Frequently asked questions

Will the robo investor decide when to sell my investment?

Yes. The robo advisor invests in a series of funds and then periodically buys and sells funds to try to optimise your portfolio. This is known as rebalancing.

Is my money safer with a robo investor?

All investing carries risk, but your investment is neither safer nor more at risk with a robo adviser than through other ways of investing.

Where your money is invested is the main indicator of how safe it is, with more risky assets offering the chance for greater returns but also higher losses. 

In the rare event of the robo advisor platform going bust, your investments should still be protected, because the robo advisor is only acting as an intermediary and buying and selling on your behalf.
