What is Diversification?


Diversification is part of investment risk management. By spreading funds over a wide variety of investment types within a portfolio, investors are able to dilute risk to any one investment and yield higher returns.


There have been many studies which demonstrate the effectiveness of this risk reduction technique. Maintaining a diverse portfolio neutralises the negative performance of some assets with positive performance in other areas.


Investment diversification is often carried out across asset classes, with calculated percentages of the portfolio to allocate to each. From stocks and bonds, real estate, to short-term investments, investors will diversify further, choosing asset classes which are separate enough to not share risk.

A shift to the right?

The rise of populism is driving a new political paradigm. But what does this mean for markets? Could more volatility and higher risk premia across asset classes be round the corner?

Is it time to retire the 4% rule?

Short-cuts have their place. If you can avoid complexity and effort, it makes absolute sense to do so. It gives you time to work on other projects, or in my case re-watch The Treble (1999), reliving the good ol’ days. However, when it comes to retirement income, short cuts may be counter-productive and nowhere is this more apparent than with the 4% rule.

Could unreliable weather be a reliable return source?

True diversification requires looking for independent return streams. You normally cannot rely on the weather, but in investments that lack of reliability is an interesting feature.

Correlation galaxies – how to grasp asset class behaviour over time

Correlations show us how assets have moved relative to each other in the past. As multi-asset investors, one of our key objectives is to identify assets that improve diversification. To do this, we try to combine assets with low or even negative correlations. This sounds easy, but can be surprisingly difficult in reality.

Emerging by name, emerged by nature

Emerging market assets have long been a source of both potential profit and peril for investors. 2017 saw an incredible streak of capital inflows into emerging market equities, bonds and currencies. Whilst returns are still characteristically volatile, this historically maverick asset class has become more mature and resilient than ever before, as was highlighted during February's market sell-off.

Correlations: when falling below the averages is a good thing

‘Less is more!’ That is what correlation wants to brag about to enhance diversification. However, following the financial crisis, many believe that correlations are at an all-time high – is this the end of low correlations? We think not.

Yield us not into temptation

In my previous post I outlined the possible benefits of using multiple asset classes to achieve a more stable and attractive level of yield from an income-focused portfolio. In this post I take aim at targeting a fixed level of yield, showing that this objective could mean you miss the big picture.
