The Recovery Baseline Test evaluates performance using three reference points: the prior peak, the subsequent trough, and the current level. A market that collapsed from a high level can post spectacular percentage gains merely because it starts from a depressed base. Meanwhile, a more stable market may show modest growth because it never suffered the same destruction. The analyst must also question whether the old peak is a legitimate destination; a peak created by speculation, indiscriminate lending, or uneconomic development may be a fabricated benchmark. The output is a contextual classification—early rebound, normalization, genuine recovery, or renewed excess—rather than an unsupported conclusion based on a single year-over-year percentage.
Origin
Jonathan Miller used this comparison to explain why heavily damaged Sand State housing markets appeared to recover faster than less speculative regions. Extracted from Masters in Business.
Core principles
- 01Percentage growth depends on the starting value.
- 02A sharp rebound can follow an extreme collapse.
- 03The former peak may itself have been unsustainable.
- 04Markets with shallow declines should not be compared directly with devastated markets.
- 05Recovery requires context, not one growth statistic.
How to run it
- 1
Establish the peak
Identify the highest relevant value before the decline and document the conditions that produced it.
Pro tip Use inflation-adjusted and nominal figures when both perspectives matter.
Watch out Do not assume the peak represented sustainable value.
- 2
Measure the collapse
Identify the trough and calculate the absolute and percentage decline from the peak. Note whether speculation or forced selling amplified the fall.
Pro tip Compare the decline with transaction volume and inventory changes.
Watch out A market can reach a statistical low before its underlying problems are resolved.
- 3
Measure the rebound
Calculate the increase from the trough to the current value. Report both percentage and absolute changes.
Pro tip Always show the denominator alongside the percentage gain.
Watch out Large percentages from tiny bases can create misleading headlines.
- 4
Calculate the remaining gap
Measure how far the current value remains below or above the prior peak. This distinguishes partial recovery from full restoration.
Pro tip Express the gap in both value and percentage terms.
Watch out Returning to an irrational peak is not necessarily desirable.
- 5
Audit the fundamentals
Compare current employment, income, credit quality, supply, and demand with the conditions at the peak and trough. Assign a contextual recovery label.
Pro tip Call an improvement a rebound when fundamentals have not caught up.
Watch out Avoid apples-to-oranges comparisons between markets with different collapse histories.
In the wild
A speculative housing market falls dramatically and then records rapid price growth. Its percentage gain looks stronger than that of New York, but it began from a much lower trough and remains far below a peak created by loose credit and uneconomic construction.
→ The gain is described as a rebound from overcorrection rather than evidence of superior fundamentals.
A struggling unit rises from £1 million to £2 million while a stable unit rises from £10 million to £11 million. The first reports 100% growth, but both added the same absolute revenue and face different historical baselines.
→ Management evaluates absolute gains, peak gaps, and operating fundamentals before allocating capital.
Common mistakes
Ranking by percentage alone
Percentage growth conceals the size and quality of the starting base.
Treating the peak as destiny
An old high produced by speculation or distorted incentives may not be a valid recovery target.
Comparing unlike declines
A devastated market and a stable market cannot be judged fairly without accounting for how far each previously fell.
Is it for you?
Best for
It is best for comparing markets, assets, businesses, or metrics after uneven declines.
Not ideal for
It is not ideal when reliable peak, trough, and fundamental data are unavailable.
From the transcript
“when you go from a dollar to two dollars, it's a dred percent increase.”
“They're not going to rise from the the ashes because it didn't really fall to the ashes.”
“But remember the high point that was reached was complete fabrication and consense.”
