The 3 best tables for every financial adviser and investor

I have read countless books on investing. Met an enormous number of financial experts and fund managers. And made pretty much every investing mistake possible!

If I could distil my learnings into one statement, it would be this: the short term is unknowable, but the long term is inevitable. 

Let me share my 3 all-time favourite tables from 30 years of investing.

The long term is inevitable

Firstly, the stock market has good years and bad, but over the long term there is only one trend, and it is up. 

Despite this being so obvious, I continue to be astounded at how investors behave during ‘bad’ years.

We are now into our 146th year on the Australian Exchange. That enormous amount of data provides the clearest guide to anyone willing to learn. During this period, the market (dividends plus share prices) has risen 117 years and declined 29 years. 

So 80.1% of the time, the market rises. One in 5 years on average, the market declines.

When the market rises, it does so by an average of 16.1%, and when it declines the average is minus 10.4%. When combined, we see that over the past 146 years, the market has averaged a return of 10.8% per annum.

Since we have become more sophisticated and introduced the Accumulation Index in 1979, the data points to an even stronger outcome. Over the 42 years since 1979, the market has risen by an average of 13.0% per annum. And this is despite some seriously scary episodes, including the 1987 Stockmarket Crash, the 1997 Asian Financial Crisis, the GFC and the fastest crash on record, Covid-19.

If there is a better table than this, send it to me …

To best understand how the market behaves over different timeframes we can break the data into rolling periods.

For example, a rolling 5 year period, is the average return over every 5 year period since 1875.

What this table below demonstrates is rather extraordinary.

If you were to invest your money in the ASX (index), turn off your screen, go away and come back in 5 years’ time, then on average you would have a 65.1% return, and there would have been only 7 occasions out of the 142 rolling 5 year periods where you would have a negative return.

If you were to invest your money in the ASX (index), turn off your screen, go away and come back in 7 years’ time, then on average you would have a 100.7% return, and there would have been only 2 occasions where you would have a negative return.

But even more remarkably, if you were to invest your money in the ASX (index), turn off your screen, go away and come back in 8 years’ time, then on average you would have a 120.4% return, and there would have been NO occasions on record where the dividends and capital growth would have been negative.

There is only one long term trend, and it is up.

Volatility is the price you pay for a seat at the table

But of course in the short term – from year to year – markets are volatile.

We’ve all seen this distribution curve below – perhaps numerous times. But I suspect that many investors have failed to grasp the most important aspect.



And that put simply is that crashes are inevitable; be ready and don’t panic at the bottom. (As I have been known to say, the best time to panic is at the top!)

Case in point, there has only been one (calendar) year in the ASX’s 146 year history, where the market fell by 30% or more – 2008. But if you panicked and sold during that crash, you would have missed an extraordinary recovery. In 2009 the market was up by 39.6% and rose in 11 of the 13 years following the crash, including by 18.8% in 2012, 19.7% in 2013 and 24% in 2019.

Know thyself. If you are prone to doing the wrong thing at the wrong time, stay out of the stock market. Or work with a trusted financial adviser who can coach you through such periods.

Timeframe, Timeframe, Timeframe

If the short term is unknowable and the long term inevitable, an investor really does need to focus on the long term.

If through age, or financial circumstances, an investor does not have the luxury of a long term horizon, then they should understand the extra risk that they are taking on. 

Remember in the stock market, volatility really is the price you pay for a seat at the table

There will be another crash. Guaranteed. If your time horizon is not beyond the next crash, or you panic and do the wrong thing at the wrong time, then discretion may be the better part of valour.
