A timely reminder not to follow momentum biases with your investments

With markets experiencing a correction demonstrating volatility in response to the US tariff announcements and recent changes, investors will see the value of their holdings go up and down from one day to the next. This can be unsettling. And therefore it is a good time to be reminded of the momentum investor bias. Being aware of this can help you to make good long term decisions when you are feeling uneasy about the markets, and importantly stop you making decisions you may regret.

This bias is really a sequence of responses to movements in markets, that can seem quite rational, but if followed can reduce your returns and potentially leave you worse off than when you started.

For this to make sense, we need to agree on the principle that investment markets go up over time, but not in a straight line. Another way to say this is that time reduces volatility and the likelihood of losses and what looks like bumpy markets across a short time period like a month, can be smoothed out when looking at a long time period, like ten years.

It follows then that our responses to short term market movements should be to look at our investments and what is happening in the world relative to our goals and the timeframe of those goals. If your key goal is 15 years away, a short term fluctuation now might be irrelevant, or even an opportunity.

The momentum investor bias can lead us into wanting to make rash decisions when investment prices go up or down.

The image below shows some of the bias responses that can take over from good decision making.

 If you look at the worst-case scenario in this illustration, an investor liked an investment (the green comments on the left), but waited until it was ‘proven’ and bought near the top of the market. They panicked at the first sign of market volatility and then as the investment moved through the market cycle and the downturn, they fell into the trap of thinking the prices would fall forever. After much hand-wringing they finally sold right near the bottom of the market before – inevitably- the prices recovered. The alternative path would have been to invest in an asset that was appropriate for their goals and plans, and to not sell them during temporary drops. Over time the asset would have increased in value. This is of course hypothetical, but it illustrates how momentum can lead us to make reactive decisions.

Investor Bias - Momentum

It is not difficult to understand the rationale. If we wait until something has increased in price, it feels like a proven and safer investment- it has a track record. What is often means though is buying at the top of the market. One of the most often repeated phrases when giving financial advice is that past performance is no guarantee of future performance. Just because an investment has risen in value does not mean it will continue to rise at the same rate.

Following this pattern, the investor bias kicks in again when prices drop, meaning we may be less likely to buy, even though that asset may be considered as being ‘on sale’.  In fact we may feel inclined to sell. The momentum investor gets increasingly worried as prices drop.

Where are we right now?

We are in the purple and orange sections. This is what makes this a timely reminder. We will soon start hearing messages in the media of capitulation. They will be statements such as “this time it’s different, the markets might fall forever.” When you hear these comments you can be confident we are near the bottom and it is a signal to do the opposite of what the capitulators are saying.

Probably the world’s most famous investor, Warren Buffett, put this succinctly when he said “be greedy when others are fearful and fearful when others are greedy.”.

If your focus is the long term, focus on the long term.
