What Is Diworsification? Definition and Meaning

Diworsification is a term first introduced by Peter Lynch. It describes how companies might invest in different areas to diversify their business, but end up worsening their overall business. Diversification is often regarded as a great way to reduce risk. However it all boils down to how the process is conducted. Some businesses benefit from strategic acquisitions. Despite that, some businesses trying to diversify might find themselves worsening their operations.

It is important to understand how a particular acquisition will positively impact the company. It is also important to know how it can be integrated. Both horizontal and vertical integration can have a positive impact. Before any acquisition is made, it is important to understand what kind of synergies it will create. Some companies are better off investing in their core business, than diversifying into unrelated industries.

Diworsification in investments

Although Peter Lynch initially used the term to describe companies, and the M&A activity over the late 20th century. Diworsification can also occur in an investor’s portfolio. One of the most debated aspects of investments has been the difference between diversified and concentrated portfolios. There are advantages and disadvantages to both approaches. Diworsification can happen in a few distinct ways. 

Picking worse investments

Either through picking investments that are worse than the ones you already have in your portfolio. This means that oftentimes investors will pick stocks to add to their portfolios with the intention of diversification, but end up with diworsification. 

Over diversifying

Another common way investors end up with diworsification is by over diversifying. Diversification is important when you conduct investments. However if you diversify your investments too much, you might end up with diworsification. Peter Lynch, who managed the Fidelity Magellan Fund for a long time, and managed to achieve great returns over the period. A fun fact is that the Fidelity Magellan Fund as of 1989 held 1,400 different stocks. His approach clearly showed that you can follow a diversification approach, without diworsification ruining your returns. However if it is not done correctly, too many stocks might spoil your portfolio.

Correlated assets

Investors also make the common mistake of diversifying into correlated assets. An example of this is when investors are bullish on a particular industry. If you buy several stocks in that industry, it is not diversification. This is because the price of correlated assets will often move in the same direction. This ends up with an averaging effect on your portfolio. Basically your risk/return profile worsens.

Position size

It is also common for investors to wrongfully size their positions when they are diversifying. This can be extremely detrimental to your returns. You might end up with a great performing asset that is a small position within your overall portfolio. 

How to avoid diworsification?

There are a few ways to avoid diworsification either as a business or as an investor.

It should also be considered the cost reduction through sinergies generated over a period of time.
