What it means
These surveys are short by design. Chief executives are asked a handful of questions about current conditions, expectations for the next six to twelve months, their own industry, and their plans for hiring, wages and capital spending.
The answers are then combined into what statisticians call a diffusion index, which measures the balance of opinion rather than the size of any change. A reading above the neutral level says optimists outnumber pessimists, a reading below it says the reverse, and the distance from neutral shows how lopsided the balance is.
The reason analysts pay attention is timing. Official figures for output, employment and investment arrive weeks or months after the period they describe, whereas survey answers describe intentions, and a chief executive who says she will delay capital spending is usually describing a decision already made.
The surveys are most useful as a direction indicator rather than a precise forecast. The change from one reading to the next, and whether several surveys agree, matters far more than whether a single index sits at one level or another.
Their main weakness is that sentiment is not output. Confidence can fall on headlines and recover without any change in spending, and samples are small and skewed towards large companies, so a reading can move simply because a few big respondents changed their mind.
Several bodies publish their own versions, including business research organisations, banks and employer associations, and each uses its own panel, questions and scale. Because the construction differs, you compare a survey with its own history rather than with another publisher's index.
In practice
Real-world examples.
Example
A recruitment firm sees a CEO confidence index drop below neutral for two consecutive quarters. It slows its own hiring of consultants and shifts marketing spend towards contract placement, which holds up better when clients freeze permanent roles. Demand falls two quarters later, broadly as the survey implied.
Example
A commercial property developer reads that chief executives expect to cut capital spending. Because office demand follows corporate expansion plans, the developer delays the start of a speculative building and renegotiates the land option instead. The decision saves holding costs during a weak leasing year.
Example
An investment committee compares three separate confidence surveys before adjusting its allocation to cyclical shares. Two have fallen sharply while the third is flat, so the committee treats the signal as unconfirmed and makes only a small change. It records the reasoning so the decision can be reviewed later.
Formula
Calculation
Diffusion Index = Percentage answering positively + (Half of the percentage answering unchanged)
Suppose a survey of 200 chief executives finds that 40% expect conditions to improve, 45% expect no change, and 15% expect conditions to worsen. Half of the unchanged group is 45% divided by 2, which is 22.5%. The index is 40% + 22.5% = 62.5, and because 50 is the neutral level, a reading of 62.5 shows clear net optimism. If the next survey found only 25% expecting improvement, 50% unchanged and 25% worsening, the index would be 25% + 25% = 50.0, which is exactly neutral, and that fall of 12.5 points in one quarter is the signal worth acting on rather than the level itself.Case study
Seen in the real world.
Oakreed Industrial Supplies is an illustrative, fictional distributor of factory consumables created to show how a sentiment index can be used. Its sales follow its customers' production volumes closely, so management wanted an early warning of a slowdown rather than confirmation from its own order book.
The finance director built a one-page monthly dashboard with three inputs: a published CEO confidence index, Oakreed's own quote-to-order conversion rate, and customer payment days. He set a rule in advance that two consecutive falls in the confidence index, combined with conversion dropping below 30%, would trigger a review of stock purchasing.
The rule fired the following year. Oakreed cut its forward stock orders by 15%, tightened credit on three slow-paying accounts, and went into a weak half-year with less cash tied up than its competitors. The illustrative lesson is that the index was useful because it was tied to a pre-agreed action, not because it predicted anything on its own.
Watch out
Common mistakes.
- Treating the index level as a forecast of growth, when it measures the balance of opinion rather than the size of any expected change.
- Comparing one publisher's reading directly with another's, when panels, questions and scales all differ.
- Reacting to a single quarter's move, when these series are noisy and confirmation across two readings is far more reliable.
Questions
People also ask.
Why survey chief executives rather than consumers?
Because chief executives control hiring and investment decisions, so their expectations translate into spending more directly.
What does a neutral reading mean?
That optimists and pessimists are balanced, which usually points to conditions continuing much as they are rather than to a sharp turn.
Can confidence surveys be wrong?
Yes, since sentiment can fall on news and recover without any change in actual spending, which is why they are read alongside hard data.
