Market Analysis
Part of Retail supply and stock trends
Separating supply constraints from weak consumer demand
Use matched product availability, sales and customer-request evidence to assess whether falling retail sales reflect supply or demand.
Falling retail sales can reflect missing stock, weaker demand or both. Compare what customers could buy with what they bought or sought, using the same products, places and dates. Sales alone cannot separate the causes.
Establish availability first
Check when each relevant product, size or variant was sellable at the advertised price in each store or online fulfilment area. Then compare sales during available periods with unfilled requests, cancellations and substitutions.
A sales fall concentrated where products were unavailable supports a supply explanation. It does not provide a precise lost-sales total: customers may have waited, substituted or bought elsewhere.
Trace the supply path as well. Compare purchase orders, supplier confirmations, receipts and allocation. A retailer can hold substantial total inventory while lacking the products customers want in the places they want them.
Test demand where stock was available
If availability stayed stable, compare units sold after allowing for price, promotions, range changes and selling days. Similar stores or fulfilment areas can help, provided their stock and customer conditions are comparable. A decline across available substitutes makes softer demand more plausible, though competition and changing product appeal may also contribute.
Australia's ABS Monthly Household Spending Indicator offers broader context for selected goods and services. It draws on bank transactions and supplementary data, with adjustments for coverage. It does not measure demand for one retailer's product.
The ABS stopped its Retail Trade publication in July 2025 as the enhanced household indicator was introduced. The two measures have different scopes and should not be treated as one uninterrupted product-sales series.
| Pattern | Plausible reading | Next check |
|---|---|---|
| Sales and availability both fall | Missing stock may suppress observed sales. | Check unfilled requests, substitutions and sales while available. |
| Sales fall while availability stays stable | Softer demand becomes more plausible. | Check price, promotions, range and comparable locations. |
| Stock falls while sales stay steady | Stock cover may be tightening. | Check incoming orders and replenishment time. |
These are hypotheses. A supplier delay may coincide with a price rise, and weaker demand may lead a retailer to cut future orders.
State the limit of the conclusion
Use matched product, place and time records to say which explanation the evidence supports. Without availability records, weak sales cannot establish weaker consumer interest. Without evidence of customer requests or a defensible demand estimate, an out-of-stock period cannot establish a precise number of lost sales. Public indicators can frame the question; the retailer's own records are usually needed to resolve it.
