As market pullbacks and volatility dominate headlines, many clients are looking to their financial advisers for guidance. We have long maintained that periods of uncertainty, like those we’ve seen so far in 2025, are the “moments that matter”.
It is during these times that advisers can add tremendous value for their clients through behavioural coaching helping clients tune out short-term market noise and focus on their long-term investment goals.
Investing can be emotionally challenging for clients, especially when their portfolio balances decline. During such times, it’s important to remind them that volatility is a natural and expected part of investing.
Consider these charts:
Pairing these two charts highlights that, despite the recent pullback, expected market volatility is not substantially higher than we’ve seen historically. Sharing this type of information with your clients can help them tune out the noise and remain committed to their long-term financial goals.

Diversification remains crucial in 2025, as Figure 3 underscores. Our fixed income team’s perspectives highlight the
The 2022 bond market sell-off was challenging for fixed income investors and may still be fresh in many of your clients’ minds. However, it might help to remind them that current starting yields are higher, providing them with a “coupon wall”. This implies that, compared with a few years ago, future bond returns are less likely to be affected by minor interest rate increases.
History has taught us that it’s hard to predict rate changes. But even a sudden 50 basis point (bps) change in interest rates (in either direction) is likely to still leave clients better off one year on, as shown in Figure 4. This chart compares the forward one-year total returns for an on-the-run 10-year German bund after a 50 bps increase or decrease in interest rates in the current market and at the end of 2021, when starting bond yields were much lower. As the chart shows, the higher starting yield on bonds today leads to the dual benefits of:
- a higher total return if rates decrease (the positive effect of capital appreciation and the higher yield are combined); and
- a yield buffer (due to the higher starting yield) if rates increase (the higher starting yield helps offset the capital depreciation).

Figure 5 also highlights that while a sudden increase in rates of 50 bps would cause similar negative initial price moves, the current higher yield on 10-year German bunds would overcome that price loss in less than a year, which is significantly faster than a few years ago.

Diversification extends beyond fixed income. There will always be an asset class, sector or security that will perform more strongly than others. But predicting these trends ahead of time is very difficult and almost impossible to do consistently. A diversified portfolio allows investors to benefit from the gains of the best-performing assets without having to guess where those gains will come from or the risk of being invested in the wrong place.
That’s why we believe a global market-cap portfolio of equities and bonds is a great starting point. Depending on an investor’s preferences and risk tolerance, models and assessments of valuation differences can offer potential ways to adjust this portfolio over time.
Our Adviser’s Alpha research has shown that periods of uncertainty and capital losses are the “moments that matter” for advisers and “Adviser’s Alpha weather”. In times of stress, clients often look to their financial advisers as guardians of their financial and emotional well-being. For advisers who are looking to positively communicate with clients during periods of uncertainty, behavioural coaching helps clients to tune out the noise. By integrating these principles, advisers can foster stronger client relationships, reduce stress and enhance long-term investment success.
