What Drives Investment Outcomes, with Jessie Kwok
AD | This episode is sponsored by Wealthify.
What matters most in investing is often not what people expect.
In this episode of The Wallet, Emilie Bellet is joined by Jessie Kwok, Chief Investment Officer at Wealthify, to unpack what really drives long-term investment outcomes, and how to think about building a portfolio you can stick to over time.
The conversation moves beyond stock picking and into the decisions that shape outcomes in a more meaningful way: asset allocation, risk, behaviour, and consistency.

Start with the goal, not the investment
A common misconception is that investing is about choosing stocks or funds.
Jessie reframes this: investing starts with understanding what you are trying to achieve. That clarity determines how much risk you take and how you structure your portfolio.
Without a clear goal, it becomes difficult to make consistent decisions or stay invested over time.
Risk is part of the process, not something to avoid
Risk is often seen as something negative, but Jessie challenges that framing.
In her view, risk is necessary to achieve long-term growth. The return from investing is closely linked to the level of risk taken, and avoiding it entirely can limit outcomes.
The decisions that matter most are simple, but not easy
When asked what drives long-term outcomes, Jessie keeps it deliberately simple:
Start investing
Take some risk
Stay the course
These ideas are straightforward, but applying them consistently, especially during periods of uncertainty, is where the challenge lies.
Asset allocation matters more than picking investments
One of the strongest messages in the conversation is that how you divide your portfolio across different types of assets matters more than individual investment selection.
Jessie explains this through a simple analogy: building a portfolio is like balancing a diet. You need a mix that supports both growth and stability, rather than relying too heavily on one element.
Different assets play different roles
Within a portfolio, different assets play different roles.
Equities are typically associated with long-term growth and are more closely tied to economic performance. Bonds, on the other hand, can help smooth volatility when markets are more uncertain.
The mix depends on how much fluctuation you are comfortable with and the level of risk you are willing to take over time.
Staying invested is where outcomes are shaped
Market volatility is part of investing, and reacting to it can undermine long-term results.
Jessie emphasises that once invested, “doing nothing” can often be the most disciplined approach. Acting on short-term noise, especially negative headlines, can lead to decisions that disrupt long-term progress.
Staying invested through ups and downs is a key part of the process.
What happens during a market downturn?
Market downturns are part of investing, and Jessie emphasises the importance of understanding what is driving them before reacting.
Rather than responding to short-term movements, she describes going back to the original thinking behind a portfolio and reassessing whether anything fundamental has changed.
She also notes that by the time markets move, reacting can mean locking in losses, reinforcing the importance of staying consistent through volatility.
When do you sell your investments?
Jessie frames selling as a strategic decision, not a reaction to market movements.
Selling is often linked to needing the money for a specific purpose, such as a major life event. She also highlights the importance of planning ahead, so you are not forced to sell at a time when markets are down.
Timing the market is less important than time in the market
Waiting for the “right time” to invest is a common behaviour.
However, it rarely feels like the right moment, and delaying decisions can mean missing out on growth over time. Historically, markets have tended to rise more than they fall.
It often does not feel like the right time to invest, but that hesitation is part of the process, rather than a signal to wait.
Volatility is not the same as loss
Jessie makes a clear distinction between volatility and risk.
Volatility refers to short-term ups and downs in value. Risk, in her view, is the permanent loss of capital.
Understanding this difference can help investors respond more calmly to market movements.
Behaviour matters as much as portfolio construction
Emotional reactions play a significant role in investment outcomes.
Jessie acknowledges that volatility can feel uncomfortable, even for professionals. Recognising how you respond to market movements is part of the process, and can help you stay consistent when markets become more challenging.
The biggest mistakes tend to sit at the extremes
Jessie sees two common patterns:
Taking too much risk, often concentrated in a few investments
Taking too little risk, by staying mostly in cash or very low-risk assets
Both can limit long-term outcomes in different ways.
Inflation quietly erodes savings
Holding large amounts of cash can feel safe, but Jessie highlights that inflation reduces the real value of money over time.
This erosion is not always visible, which can make it easy to overlook.
What role does AI play in investing?
Jessie notes that AI is increasingly used to support tasks like analysing data, summarising research, and spotting patterns.
However, she highlights that investing still requires human judgment. Taking risk involves conviction and accountability, especially when decisions do not go as expected.
Costs and diversification are often overlooked
Two final points Jessie highlights:
Costs matter more than many people realise
Diversification helps manage risk across different parts of the market
These are less visible than market movements, but they play an important role over time.
Key takeaway
Rather than focusing on short-term movements or individual investments, the conversation highlights the importance of clarity, appropriate risk, diversification, and consistency over time.
It is less about reacting, and more about building something you can stick to.
