The error of reacting to market falls

Being an investor is never easy because, as humans, we tend to live in the moment responding to our emotions, the environment around us and the circumstances we find ourselves in. From an evolutionary standpoint that has served us well as a species helping us to survive, but as investors we need to remain focused on the long-term goals that we have and not what is going on in the day-to-day, month-to-month or even year-to-year of the markets. This is evident from the two charts below.

Each of these charts show that if we listen to this noise, we would spend most of our time being afraid of markets instead of embracing them for the returns that taking on sensible risks should deliver. In equity market jargon, a ‘correction’ is deemed to be a fall of 10% or more and a ‘bear market’ is a fall of 20% or more. The columns are the annual returns of the market, and the diamonds represent the magnitude of fall from the market high in that year.

It is pretty evident that any investor looking to profit from this would need some amazing form of 20-20 foresight to predict these short-term market movements, acting in advance of them happening and then getting back into the market again at the appropriate time. Simply reacting, post-event, to market falls will invariably be a losing strategy.

In reality, at any point in time, all of the information held by all investors trading in markets is reflected in current prices quite efficiently. Prices will therefore move only on the release of new information, which is by definition a random event. As the Nobel Laureate Professor Robert Merton recently stated[1]:

‘If the market is disagreeing with me, or doesn’t seem to be aligned with me, that could be that I know things the market doesn’t, but it also could be that the market knows things [I] don’t!’

Investors were reminded in 2022 that bond returns can go down as well as up. The same challenge in terms of reacting to falls in bond markets applies. In almost every year, bond markets fall from an intra-year high.

Trying to time when to be in or out of bonds – and presumably into cash – could result in eroding away the term and credit premia that a sensible structure of short-dated global bonds hedged to Sterling has the opportunity to provide for those focused on their true investment horizons.

As the wise industry consultant and author Charles Ellis states:

‘In investing, activity is almost always in surplus!’

We agree. Remain focused on your long-term goals, stay invested and rebalance when required, for a simpler life and the likelihood of better outcomes.
