Missing the best days in the market

Most investors – at some time – will be either tempted to time when to be in or out of equity markets – or wish they had when markets fall.  It would be great to be able to capture the upsides and avoid the downsides, but that is wishful thinking.

Investors may well underestimate the rapidity and magnitude of the movements that markets make, although the very material double digit daily moves around the Covid- crisis (March 2020) provided a useful lesson. In fact, a small number of days account for much of the market movement over time.  Picking which those days are – either to be in or out of the markets – is an extremely difficult prospect and the chances of long-term success are rare.  An analysis of missing the best days in the market (Albion, 2023) provides some food for thought, as the figure below illustrates.

Whilst these types of study imply a binary approach to being invested in equities or cash, which is a somewhat unreal scenario, it is evident that a few good days, weeks or months drive the bulk of market returns and missing them can be costly. Missing the best 30 days in this 30-year period deliver only 17% of the rewards that the market delivered[1].

Likewise missing the worst 30 days would be highly beneficial, yet the ability to pick them does not seem to show up in the data. The October 2022 Liz Truss/Kwasi Kwarteng ‘mini-budget’ in the UK provided evidence of just how quickly new information can impact markets, in that case the bond market.  Being right is quite a challenge. Being wrong can be very costly. The odds of success in market timing are slim.

A seminal piece of UK research (Cuthbertson et al., 2006) concluded that only around 1.5 % of UK equity funds demonstrate positive market timing ability.  The Nobel Laureate Professor William Sharpe agrees:

‘An [investor] who keeps assets in stocks at all times is like an optimistic market timer. His actions are consistent with a policy of predicting a good year every year. While such a manager may know that such predictions will be wrong roughly one year out of three, such an attitude is nonetheless likely to lead to results superior to those achieved by most active market timers.’

Stay invested!

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 parlance, 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 regularly, for a simpler life and the likelihood of better outcomes.
