Economics

Economics itself won’t actually make money for you, but the correct application of economics to the market should certainly help. The basic rule is that the market tends to anticipate – therefore, the share price often moves BEFORE the economic even takes place. So, for example, if there is expected to be a period of expansion or growth in the economy, then the share market will tend to rise well before that expansion takes place, in anticipation of the growth. Often, if the growth is less that expected, that can be seen as negative given the fact that the market has already moved to anticipate a particular rate of growth.
This introduces the concept of discounting. For example, the future possible event is discounted into today’s price already… and continuously gets discounted in the price as sentiment changes, forecasts change, etc.
What is the future dividend likely to be? Is it likely to go up or down? How does the expectation change over time? In other words, the current price is a reflection of what the future dividends may be… as the current price has discounted the future dividends already.
You could say that the current market price is really just the average of all investors’ discounted cash flows of future dividends. Each person is different – has different views of the future, different views on risk, etc… so the share price is always moving… and has risen/fallen in anticipation of any future news. When the expectation is incorrect, you might get a sudden change in the price as the market ‘discounts’ the new or changed information into the current share price.
So, let’s get back to some basic economics
The aim here is to keep it simple and to develop some basic economic concepts – some of which may help with your stock market analysis. After all, we all live in the real world, so some awareness is good.
Let’s look at the Balance of Payments (BOP)
A country makes many types of payments to other countries – imports of goods and services, international schemes, insurance and other services, interest, dividends, repayment of loans, outgoings as a result of disinvestment, etc
A country also receives many types of payments from other countries. When the outgoing exceeds the income, then any shortfall or deficit is met be the country’s reserves. If the income exceeds the outgoings, then any surplus is added to the reserves. These reserves are finite, meaning that if they are depleted, or insufficient to meet the deficit, the country would have to either borrow the money or sell one of its overseas assets.
When a country’s reserves are high, and the country is “liquid”, interest rates come down and economic growth is stimulated. The opposite, however, is also true. When the reserves are low, and liquidity becomes lower, interest rates go up and economic growth slows down.

So, the country’s reserves can be affected in several ways:
- Imports of goods and services and exports of goods and services create a positive or negative ‘gap’ in the trade account (goods) balance and the services account (services) balance.
- Some goods and services are impacted by the exchange rate. For example, South Africa is a large exporter of gold (goods and merchandise). When the gold price changes, or the exchange rate changes, affecting the price of gold, this impacts the trade account gap as well.
- Capital flows, both long term and short term, impact the reserves. (This is mainly investments into and out of the country). This is largely dependent on local interest rates. For example, low interest rates make it attractive to borrow locally – often resulting in an outflow is capital.
These statistics/figures are usually readily available in the press or online.
The above results in the reserves fluctuating over time – which in turn tends to drive the business cycle. When the country’s reserves are high, interest rates often come down, resulting in good economic growth results. On the other hand, when a country’s reserves are low, interest rates tend to go up, tightening liquidity and slowing economic growth down. These two conditions tend to fluctuate over time.
It is particularly useful to pick up a change in the business cycle, or even start anticipating changes before or as they happen. The business cycle can change very slowly over time, and there are several indications of where the cycle is currently, as well as any future impending changes in the cycle before is happens.
As we discussed before, the stock market will often discount these changes before they happen, so as you become better at spotting changes in the business cycle, so you will become a better at anticipating changes in the stock market.
Remember, the stock market will often lead the economy. Often, the night is darkest just before dawn, so we need to look for signs of the most intense dark.
What are these indications that the business cycle is changing…?
- Unemployment – headlines might focus on things like redundancies, the “brain-drain” and the shortage of skilled manpower. When the level of employment is high and everything seems super-positive, the economy is probably getting close to a recession. When unemployment and redundancies are at their worst, the economy is probably starting to get close to the bottom and a turnaround could be expected soon.
- Interest rates – interest rates will typically be going up when the economy is near the top and coming down when the economy is near its bottom. An increase in interest rates, although an immediate indication of health, will often lead curb the economic growth as it calms inflation.
- News – It is worth keeping an eye on how the markets react to different types of news. When everything seems rosy and optimistic and everybody is bullish then it is indicative of an uptrending stock market, or bull phase. Once you see worse than expected company results coming out and the share price hardly moves down, then you know that you are either in, or nearly in, a bull market.
- Bad debts – bad debts tend to reach a peak when the economy is at its lowest, as do insolvencies.
- Consumers/customers – shops tend to seem emptier during a recession. If it suddenly seems that there are a lot of empty shops and things really seem dire, the recession is probably near its bottom.
- Sales – If you seem summer and winter sales that seem to last longer than usual, it may indicate that stores have an overstocked position, which is a sign of the beginning of a recession. Conversely, a shorter sale coming which tends to be later than often indicates that the stock levels have come down, which may imply an upturn in the near future.
- Advertising/building – the thinner the advertising pages, and the less advertising you see, might be an indication of a recession coming to an end. Similarly, as the cranes disappear on the city skyline, the indication is that the recession is almost over.
- Extreme optimism/pessimism – in short, when things are looking their worst, expect a change for the better. When things are look amazing/fantastic, expect a change for the worst.
Fiscal and monetary policy
Fiscal policy mainly concerned with the budget set by the government – specifically the degree of economic stimulation through increased or decreased expenditure and higher or lower taxation rates. For example, higher expenditure or lower taxes will stimulate the economy, resulting in short-term growth. Fiscal policy should only be used to reduce the effect of an extreme in the business cycle in order to influence the timing of the change, and not the change itself. If the stimulus, for example, is continued for a longer term, the resulting growth or ‘boom’ may be extended beyond its normal turning point, which could result in out of control inflation… or other larger issues. Fiscal policy is useful for the short term, rather than being continued for too long.

It should be noted that the government don’t always get things right with their budgets, or work according to the rules. Monetary policy is administered by the Central or Reserve Bank and is more concerned with the amount of money supply in the economy. The money supply impacts interest rates and the exchange rate directly.
So, it I useful to think in terms of supply and demand, where interest rates are really just another way of saying ‘the cost of money’. if money is in short supply (money supply is low or reduced), there is a great demand for money, relative to the supply, which will tend to push interest rates higher. The opposite is also true, where money supply increase, the cost of money gets cheaper, resulting in lower interest rates.
The supply of money is controlled by the central or reserve bank changing how much lending the retail and commercial banks are allowed. Increasing the level of lending increases the supply of money. Therefore, you should expect a higher value of transactions to take place in the economy (a higher level of economic activity or growth). This in turn results in a higher level of imports relative to the level of exports, impacting the balance of payments, and lowering the reserves – resulting in a decrease in the economy over an extended period of time.
Monetary and Fiscal policy should act together. It is usually only when you start to get a change in both policies that you start anticipating changes in the trend of the stock market. Economics tends to establish the primary trend in the market – Bullish or Bearish
