Cycles of the economy and the stock market

Lesson in Course: Market movements (beginner, 7min )

I've heard of the terms market cycle or business cycle before. What does it mean and what do I need to know as an investor?

The stock market is forward-looking and often categorized as a leading indicator of the economy. As investors, we invest for the future and not for the present; however, we need to know if the future looks bright or if we need to brace ourselves for some pain. Understanding the economy allows us to do so.

The business cycle

We can break the economy's health into four phases that occur in cycles, with one phase following another. The four phases are: expansion, peak, contraction, and trough and are collectively known as the business cycle. While the concept is straightforward, economists, investors, and people use varying terminology to describe this cycle. A simple way for us to make sense of the business cycle is to imagine it as a roller coaster ride. We can either be going up towards the top or coming down towards the bottom with the ride repeating.

Let's visualize the cycle first and then reconcile the differences in terminology.

 

Expansion

The expansion phase is marked by increased productivity, increased spending, and investing from both the private sector as well as the government.  This phase is shown as the upward sloping part of the graph where aggregate economic activity is increasing.

Peak

Near the top, we arrive at the peak. The peak is signaled by continued slowing of growth down to 0 before growth turns negative. The peak is often called the boom.

Contraction

After the peak, the economy undergoes a contraction, which can be referred to as deceleration or a recession. During a recession, jobs are scarce, housing prices drop and both consumers as well as businesses spend less and save more. 

Trough

The trough, or depression, is the very bottom of a contraction right before the cycle turns over into expansion again. Troughs are signaled by slowly increased economic productivity. The increase will eventually lead to an expansion or recovery and the cycle repeats itself.

Why are markets cyclical?

Markets are cyclical due to static effects, shocks, and economic policymakers. Below is a short video covering these points.

Previous shocks include the Mortgage/Financial crisis in 2008 that launched a global recession that lasted for years. Most recently, COVID-19 is a shock that's already started global economic contractions. At the time of this lesson, it's still unclear just how long the contraction period will be.

 

Economic policymakers

To counteract shocks and stabilize the economy, the central bank and the federal government implement both monetary and fiscal policies.

The central bank

The central bank, or The Federal Reserve, is the primary government economic policymaker in charge of making sure that inflation and excessive unemployment are under control. The Federal Reserve enacts monetary policy, or policy governing the money supply in an economy. Quantitative easing is an example of a monetary policy.

Federal government

The Federal Government is different than the Federal Reserve and enacts fiscal policies. Fiscal policies target the total level of spending in an economy.

Combined, both policymakers are necessary to keep the economy on track. An easy way to think about the relationship between the two is that the central bank, monetary policymaker, makes money available while the federal government works on distributing that money and determines how the money is being spent.

Actionable ideas

Knowing where we are in the business cycle and what cycle is next is important when considering our investment options. If we are arriving at a peak, we would want to start to invest in stocks or assets that perform well in contractions. In the next lesson, we'll cover how to identify where we are in the business cycle.
