“The investor’s chief problem — and even his worst enemy — is likely to be himself.”

The Behaviour Gap
A Dalbar study using analytics and data from Lipper and the Investment Company Institute showed that investors do far more harm to themselves than they realize. It revealed that between 1992 and 2012, the S&P 500 returned 8.21% while the average investor received just 4.25%. This difference is known as the “Behaviour Gap”. What causes it? Simple — investors do the wrong things at the wrong time.
6. Investing For Yield Instead of For Total Return
7. Letting Your Cost Basis Dictate Investment Decisions
8. Leverage
The worst mistake of these eight is the one you are about to make. Therefore, these eight mistakes are being shared with you in no particular order of importance:
1. Under-Diversification
Investing professionals tell us that we need to be invested in different asset classes, categories, stocks, industries, countries and so on, in order to reduce portfolio volatility or risk. Individual stocks will have both company specific (unsystematic) risk as well as market (systematic) risk. That is why the price volatility of a single stock is generally greater than the price volatility of the market index, such as the S&P500 or TSX300. To reduce or eliminate the company specific risk of a single stock, you must hold other stocks whose price movement is different, or uncorrelated to that single stock. Studies show that when you hold a basket of 15-20 uncorrelated stocks from different industries, sectors, or countries, company specific (unsystematic) risk can be virtually eliminated. This means your portfolio will be less volatile overall. To lower volatility and risk even further, your portfolio should include other asset classes, such as treasury bills, bonds, commodities, and other types of investments.
2. Over-Diversification
On the other hand, too much diversification can also be detrimental. Owning too much of everything can amount to owning nothing because it takes away the potential impact of big gainers on your portfolio’s performance. As discussed above, diversifying your investments is needed to reduce volatility or risk, but over-diversification can subdue the overall performance of your portfolio, and make it harder to manage. The key is to strike a balance between diversifying enough to reduce risk and yet avoiding over-diversification which stifles performance.
3. Euphoria/Overconfidence
Overconfidence comes when our portfolios have done well. The greater the gains are, the greater the overconfidence becomes, which then leads to euphoria. This could be a dangerous time, because then we tend to ignore the risks to our principal when making investment decisions. We start to believe that we “can’t miss”, and then commit some of the 8 great mistakes, such as under or over-diversifying, speculating and leveraging. Whenever we feel we’re invincible, it is a good time to sit back and assess where we are in relation to our financial plan and whether or not anything needs to be done. It may be a good time to call your investment advisor, who being your behavioural coach, is likely the best one to give you some advice.
At the other end of the spectrum, when our portfolios are doing poorly, it may create dismay and fear. The greater the losses become, the greater the level of fear, which can eventually lead to panic. Then we act irrationally, often resulting in selling investments at the wrong time. We forget that markets inevitably go through cycles of ups and downs. If we don’t sell and leave our portfolios alone, it will likely go back up again, often higher than ever before. At these times, your investment advisor’s role as Behavioural Coach is perhaps of the greatest value to your portfolio. So if you feel the throes of panic setting in, pick up the phone and talk to your advisor.
