What it means
A top-down investor begins by asking which broad conditions are likely to matter most. These include economic growth, inflation, interest rates, exchange rates and government policy.
From there, the investor decides how much to place in different asset classes, such as shares, bonds, property and cash. The next step is to choose regions or sectors that should benefit from the expected conditions.
If rising interest rates are expected, for example, the investor may favour banks and avoid sectors that are sensitive to borrowing costs. Only after those choices does the investor select specific companies within the favoured areas.
The attraction is that it gives a clear structure and keeps the investor focused on major drivers. It can also help avoid owning a great company in a sector that is heading into a downturn.
Many large institutions use a top-down framework to set their overall allocation. The weakness is that economic forecasting is difficult and often wrong.
An investor can choose the right sector and still pick poor companies, or choose the right company at the wrong time in the economic cycle. The approach also relies on the assumption that macro trends are more important than the quality of the individual business.
Many professionals combine the two approaches. They may use a top-down view to set broad limits on sector weights and then use bottom-up research to choose the best companies within those limits.
This helps to balance big-picture thinking with careful analysis of individual businesses. For finance teams, the same logic appears in budgeting.
A top-down budget starts with a company-wide target, such as overall revenue growth, and allocates it to divisions, while a bottom-up budget builds from the detailed plans of each department. Understanding both methods helps in discussions with investors and in internal planning.
In practice
Real-world examples.
Example
A pension fund committee decides to hold 55% in equities, 35% in bonds and 10% in cash based on its view of the economy. The equity manager then chooses regions and sectors, and individual shares are selected last.
Example
An investor expects an economic slowdown and reduces holdings in sectors that depend on consumer spending. The investor shifts money to healthcare and utilities, then researches the best companies in those sectors.
Example
A company's finance director builds next year's budget by starting with a revenue target of $50 million. The target is split among three divisions, based on market size, and each division then plans how to achieve its share. Later the director compares this with the divisions' own bottom-up forecasts, and the gap between the two becomes the basis for discussion.
Formula
Calculation
Amount per stock = portfolio value x asset class weight x sector weight within the asset class / number of stocks in the sector
Suppose an investor has $1,000,000 and decides on 60% in shares. Within shares, the investor decides to put 25% in healthcare and will buy 5 healthcare companies equally.
Amount in shares = 1,000,000 x 60% = $600,000.
Amount in healthcare = 600,000 x 25% = $150,000.
Amount per company = 150,000 / 5 = $30,000.
The investor made three big-picture decisions before choosing any company, which is the essence of the top-down method.Case study
Seen in the real world.
Meadowbank Investment Partners is an illustrative, fictional firm that manages a balanced fund. At the start of the year, the investment committee expected inflation to fall and interest rates to be cut within twelve months.
Using a top-down approach, the committee increased its allocation to bonds and to sectors that tend to benefit from lower rates, such as housing and utilities. Only then did the analysts search for the strongest companies in those sectors.
The illustrative outcome was mixed. The sector call worked, but one of the chosen companies had weak management and its shares fell, which reminded the committee that the big-picture view does not remove the need to study each company. It now pairs its top-down framework with a checklist for company quality. The checklist covers management track record, debt levels and cash generation, so that a good sector call is not undermined by a weak company.
Watch out
Common mistakes.
- Assuming economic forecasts will be right, when forecasting is difficult and even experts often miss turning points.
- Choosing the right sector but skipping research on the individual companies.
- Treating top-down and bottom-up as opposites, when many investors combine them.
Questions
People also ask.
What is the difference between top-down and bottom-up investing?
Top-down starts with the economy and works down to companies, while bottom-up starts with the company and pays less attention to the economy.
Who uses top-down investing?
Asset allocators, macro funds, pension funds and many portfolio managers use it to set their overall mix before choosing investments.
Does top-down investing work?
It can work when the economic view is right, but it fails when forecasts are wrong or when company-specific problems outweigh the big-picture trend.
