What it means
Underperformance only means something once you have said what you are measuring against. A fund that returns 6% in a year has underperformed if its benchmark returned 8%, even though investors made money.
The same fund would have outperformed if the benchmark had returned 3%. Choosing the right yardstick is where most of the judgement sits.
A global equity fund should be compared with a global equity index, not with a bank deposit rate, and a division should be compared with a budget or with similar divisions rather than with the whole group. A poorly chosen benchmark can make weak results look strong or strong results look weak.
In business reporting, underperformance is usually expressed as a variance, which is simply the difference between actual and expected results. Finance teams track it monthly for revenue, margin and cost lines, then investigate the largest gaps.
Persistent underperformance can trigger a recovery plan, a change of management, a sale of the asset or a write-down of its value. It helps to separate underperformance from poor absolute results.
A business can grow sales by 5% and still underperform if its market grew 12%, because it lost share. Equally, a company can post a loss in a downturn and still outperform peers who lost more.
Time period matters too. One quarter of underperformance can be noise, whereas three or five years suggests something structural, such as higher fees, weak strategy or an uncompetitive product.
Good analysts look at the trend and the cause before deciding whether to act. Fees and costs are a frequent reason for the gap.
An active fund that charges 1% a year has to beat its benchmark by at least that much before investors see any advantage. Over many years even a small annual shortfall compounds into a large difference in final value, which is why long-term investors pay close attention to it.
In practice
Real-world examples.
Example
A retail chain budgets $12,000,000 of sales for the quarter and delivers $11,100,000. The $900,000 shortfall is 7.5% below budget, so the finance director asks regional managers to explain which stores and product lines fell behind. Each manager then reports back within two weeks with a recovery plan, and progress is tracked in the monthly management pack.
Example
A software company grows annual recurring revenue by 10% while the listed software companies it compares itself with grow by 18%. The board describes this as underperforming the peer group and asks management for a plan to lift sales productivity.
Example
A pension fund reviews an equity manager who has trailed the agreed index by about 1.5% a year for four years. The trustees conclude that the gap is too persistent to be bad luck and move the mandate to a lower-cost index fund. The switch is expected to save the fund roughly 0.8% a year in fees, which also helps its net return.
Formula
Calculation
Underperformance = Benchmark result - Actual result (when the actual result is lower)
Suppose a manager runs a $500,000 portfolio that returns 6% over the year, while the benchmark index returns 8%.
Actual gain = $500,000 x 6% = $30,000
Benchmark gain = $500,000 x 8% = $40,000
Shortfall = $40,000 - $30,000 = $10,000, which is 2 percentage points (8% - 6%) of underperformance.
If the manager charged a 1% fee, that fee alone accounts for $5,000 of the gap, so about half of the shortfall is explained by cost rather than by poor stock picking.
Compounded over 10 years, the same $500,000 grows to about $895,000 at 6% but to about $1,079,000 at 8%, a difference of roughly $184,000, which is why a small annual gap deserves attention.Case study
Seen in the real world.
Harbourline Foods is an illustrative, fictional packaged-goods company with a $40,000,000 annual budget for its snacks division. Halfway through the year the division had delivered $17,000,000 against a half-year budget of $20,000,000, and management initially described the shortfall as seasonal.
The finance team compared the division with a basket of similar fictional competitors and found that the category had grown 4% while Harbourline's snacks sales had fallen 6%. That showed the problem was not the market but the company's own pricing and shelf placement.
After a pricing review and a new promotional calendar, the division recovered to roughly 95% of budget by year end. The lesson of the illustrative story is that a benchmark turned a vague excuse into a diagnosis. Management also added a quarterly benchmark review to the divisional reporting pack, so that any future gap against the category would be spotted within weeks instead of months, and the board agreed that a gap of more than 3% would trigger an automatic review.
Watch out
Common mistakes.
- Assuming that underperforming means losing money, when it only means doing worse than the chosen benchmark.
- Judging performance against an easy or irrelevant benchmark, which flatters weak results.
- Reacting to a single short period of underperformance without checking whether the cause is temporary or structural.
Questions
People also ask.
Is underperformance always bad news?
Not always, because a fund that deliberately takes less risk than its benchmark may trail it in a rising market while protecting capital in a falling one.
How do you measure underperformance for a business unit?
Compare actual results with budget, with the prior period and with a group of similar businesses, then explain the variance line by line.
What is the opposite of underperform?
Outperform, which means delivering a better result than the benchmark.
