Portfolio Structure

10 January 2022 By PDSNET

Private investors often accumulate a portfolio over a number of years, as and when they have surplus capital available. Typically, they do not give much thought about how that portfolio should be structured to maximize return and minimize risk.

To begin it is important to think about how many shares you want to have in your portfolio. If you are a complete beginner, it is usually best to begin a with small quantity of a single share. This is because, when you begin, you have no experience and your knowledge is entirely theoretical. The mistakes that you make with an investment of R10 000 are exactly the same as the mistakes you can make with R100 000 or even with R1m – they are just less painful.

We advise beginners to save up until you have at least R10 000 before carefully selecting a single share. The dealing costs in an investment of less than R10 000 will be a relatively high percentage of the value of the transaction – which means that the investment will have to grow significantly before it is “in-the-money”. Then, once you have saved up another R10 000 buy a second share – and so on.

The next question to ask is, “How many shares should you have in your portfolio?”

The objective of having a diversified portfolio is to reduce unsystematic risk. If you have only one share then you are totally exposed to what happens to that particular company. When you have two shares the risk is reduced by 50% assuming that you have the same amount of money in each. If you add a third share you reduce your risk further (by 33%), the fourth share reduces risk by a further 25%. Studies in the United States have shown that by the time you reach 15 shares, adding a 16th share has an almost negligible impact on your risk.

But of course, each share that you add to your portfolio will spread your available time more thinly. And in the share market, time is your most important resource, not money – because how you spend your time will determine how you spend your money.

So, we advise private investors to aim for a portfolio of between 5 and 8 shares. If you are working in an investment club, you could perhaps increase this by getting individual members of the club to focus on specific shares and report back to the group. Individual private investors typically have to go to work during the day and so have a limited amount of time to focus on their investments. They must use that time wisely.

Take the time to watch the following video: Portfolio Structure attached to our lecture Module 6, “Choosing Winners”.

The video lays out the mechanism that we suggest you use when structuring your portfolio. Obviously, your watchlist must only include those shares which you consider to offer the best opportunities in the market at the moment. You do not want to waste your precious time on shares which are going nowhere. If you intend to have 30 shares in your watchlist, then it follows that you are looking for the top 1% of opportunities in the market. If the share that you are looking is not, in your opinion, in the top 1% of opportunities then you should discard it.

In your search for good investment opportunities, look for those companies that have survived the COVID-19 pandemic and are poised for growth as the economy recovers.

A good example of this might be Lewis – which we recommended to you on 2nd September 2020 in our Confidential Report, when it was trading for 1668c. We drew your attention to the fact that it was then trading on a P:E of 6.41 and a dividend yield of 8,87%. It also had the salutary advantage of being completely debt-free – which enabled it to get through the pandemic and even grow. Today that share is trading for 4900c – a gain of 193,8% in 16 months. Consider the chart:

Lewis (LEW): February 2020 - 7 January 2022. Chart by ShareFriend Pro

We still see Lewis as a good buy today on a P:E of 6,9 and a dividend yield of 6,37%.

US Economy

There has been a debate among international investors about whether the US economy will move into recession as a result of rising interest rates being applied by the Federal Reserve Bank (“the Fed”) to control inflation. The last time that the inflation in America reached these levels was in 1981 and then the Chairman of the Fed, Paul Volcker,

The Rand

South Africans will have been watching the steady decline in the rand to below R17 to the US dollar with resignation and some despair. It seems as if our currency is always losing ground, making it more and more expensive to travel overseas while increasing local inflation and especially the price of petrol.

By opening an Easy Equities account, South African investors can apparently buy shares in Elon Musk’s disruptive American electric vehicle (EV) company, Tesla (TSLA).

JSE Overall Index versus S&P 500 Index

The comparative relative strength index (CRSI) is a very useful indicator. It simply divides one data stream in your software by another and then draws a chart of the result. This enables you to compare the growth in the two data streams against each other graphically.

The Anatomy of the Bear

As the bear market unfolds on Wall Street you either hold shares or you are sitting in cash. For those who are holding shares, as we have said consistently, you need to watch your stop-loss levels very closely because you are operating in a market where the odds are decidedly against you.

For those in cash, your position is

Bear Trend

We never regarded the COVID-19 fall of the S&P500 in March 2020 as a bear trend. In our view it was always a technical aberration caused by the “black swan” event of the pandemic. It caused a temporary downward spike which lasted from February to August 2020, but it was never a true bear market.

Uncharted Territory

The world has entered a turbulent time, the outcome of which will largely determine the future order of things. There are six great areas of uncertainty which the private investor should formulate a coherent opinion on:

Investors should be riveted to the progress of the S&P500 index these days. As we said in our article three weeks ago, the S&P is teetering on the edge of a bear trend. Following that article, the index climbed back up and then on the US Memorial Day weekend it encountered significant

Basic Fundamentals

Public, listed companies are required to report back to their shareholders on a regular basis. They must produce audited financial statements after the first six months of their financial year (interims) and then again at the end of the financial year (finals). Listed companies must produce these statements within 3 months of the end of their
