As I write this, the novel coronavirus (2019-nCoV) has infected 43,103 people globally and caused the deaths of 1,018 people. China has been the hardest-hit country, accounting for the lion’s share of the infected cases (42,708) and deaths (1,017).
This disease outbreak has already caused plenty of human suffering, especially in China. No one knows how widespread the 2019-nCoV will become around the world. The eventual impact of the virus on the global economy is also impossible to determine. If you’re an investor in stocks in Singapore and/or other parts of the world, it’s understandable to be worried.
A look at the past
But in times like these, we can look at history to soothe our fraying nerves. This is not the first time the world has fought against epidemics and pandemics. If you’re curious about the difference, this is the definition given by the CDC (Centres for Disease Control and Prevention) in the US:
“Epidemic refers to an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area… Pandemic refers to an epidemic that has spread over several countries or continents, usually affecting a large number of people.”
My blogging partner, Jeremy, included the chart below in a recent article. The chart illustrates the performance of the MSCI World Index (a benchmark for global stocks) since the 1970s against the backdrop of multiple epidemics/pandemics. He commented:
“As you can see from the chart… the world has experienced 13 different epidemics since the 1970s. Yet, global stocks – measured by the MSCI World Index – has survived each of those, registering long term gains after each outbreak.”
The chart does not show what happened to stocks in the 1910s and 1920s. In 2009, the H1N1 pandemic arose (this is covered in the chart), but it was not the first time the virus had reared its ugly head. The first H1N1 pandemic lasted from 1918 to 1920. The first outbreak infected 500 million people worldwide, of whom 50 million to 100 million died. It was a dark age for mankind.
A tragedy for us, a normal time for investing
But from an investing perspective, it was a normal time. Data from Robert Shiller, a Nobel Prize-winning economist, show that the S&P 500 rose 10% (after dividends and inflation) from the start of 1918 to the end of 1919. From the start of 1918 to the end of 1923 – a six-year period – the S&P 500 rose 48% in total (again after dividends and inflation), for a decent annual gain of 6.8%. There was significant volatility between 1918 and 1923 – the maximum peak-to-trough decline in that period was 30% – but investors still made a respectable return.
I wish I had more countries’ stock market data from the 1910s and 1920s to work with. But the US experience is instructive, since some historical accounts state the country to be the source of the 1918-1920 H1N1 pandemic.
I’m not trying to say that stocks will go up this time. Every point in history is different and there’s plenty of context in the 1910s and 1920s that’s missing from today. For example, in December 1917, the CAPE ratio for the S&P 500 was 6.4; today, it’s 32. (The CAPE ratio – or cyclically-adjusted price-to-earnings ratio – is calculated by dividing a stock’s price with its average inflation-adjusted earnings over the past 10 years.) The interest rate environment was also drastically different then compared to now.
There are limits to the usefulness of studying history. But by looking at the past, we can get a general sense for what to expect for the future. And history’s verdict is that horrific pandemics/epidemics have not stopped the upward march of stocks around the world.
The Good Investors’ take
The human tragedies of a virus outbreak like what we’re experiencing now with the 2019 n-CoV are painful. But as investors, there’s no need to panic if we’re investing for the long run – which is what investing is about, in the first place – and assuming our portfolios are made up of great companies.
