The four primary signals
OAV's view of dealer inventory health is a composite of four underlying signals. Each measures a different dimension of alignment between a dealer's current inventory and local market demand. None of the four is a leading indicator on its own — combined, they triangulate a directional read on inventory health.
Aging inventory exposure
- What it measures
- The share of a dealer's inventory that has been on the lot longer than a healthy turn-cycle threshold for the body type and market.
- Why it matters
- Aged inventory ties up floorplan capital, depreciates daily, and tends to require below-market pricing to clear. Aging exposure is the single strongest leading indicator of forced markdowns.
- Where OAV surfaces it
- OAV surfaces aging exposure via Demand-Verified velocity cohorts + per-listing days-on-lot vs market-average comparisons on every dealer page.
Retail velocity
- What it measures
- How fast a cohort of comparable vehicles is selling in the local market, measured as median days-to-sale for a recent sold-vehicle cohort.
- Why it matters
- Retail velocity is the demand-side counterpart to days-on-lot. A market with strong velocity will absorb inventory faster regardless of pricing; a slow-velocity market will require deeper discounting to move the same units.
- Where OAV surfaces it
- Demand-Verified labels combine PTM (price-to-market) with retail velocity evidence. A Demand-Verified Great Deal is priced below market AND backed by recent cohort sell-through.
Inventory turn
- What it measures
- The rate at which a dealer's inventory cycles through — typically expressed as turns-per-year or days-of-supply at current sales pace.
- Why it matters
- High-turn dealers run leaner floorplans, capture more aggressive trade-in pricing, and require less below-market discounting to clear inventory. Low-turn dealers carry more aging exposure and pricing-pressure risk.
- Where OAV surfaces it
- Per-dealer inventory totals + segment mix surface on every OAV dealer page. Industry-aggregate turn analytics live on the gated research surface for institutional audiences.
Pricing pressure
- What it measures
- A directional indicator of how aggressively a dealer (or group, or market segment) is discounting against typical comparable ranges.
- Why it matters
- Pricing pressure rising in a segment signals either oversupply (too much inventory chasing too few buyers) or demand softening (buyers walking away at current prices). Both predict near-term margin compression.
- Where OAV surfaces it
- OAV's Pressure Index methodology surfaces directional pricing pressure for U.S. public auto retailers. Pressure Index is a directional INDICATOR — not a forecast, not a margin metric.
What OAV does NOT claim
- Pressure Index is not a forecast. It is a directional indicator of below-market discounting intensity, not a prediction of future gross or margin compression.
- Aging exposure is not a stale-inventory ranking. The signal is normalized against local cohort velocity, so a 60-day truck on a fast-velocity market reads differently from a 60-day truck on a slow-velocity market.
- Retail velocity is not a transaction-price feed. OAV measures days-to-sale velocity from recent sold-vehicle cohorts; out-the-door transaction prices are NOT in the dataset.
- Inventory turn is not floorplan analytics. OAV's view is external (units listed + days observed); internal floorplan cost-of-carry remains a dealer-side calculation.
Frequently asked questions
- What does dealer inventory health mean?
- Dealer inventory health is a composite picture of how well a dealer's current inventory is aligned with local market demand. The four primary signals are aging inventory exposure (how much inventory is past its healthy turn cycle), retail velocity (how fast comparable cohorts are selling locally), inventory turn (the dealer's own turns-per-year), and pricing pressure (how aggressively the dealer is discounting against typical ranges). OAV surfaces each of these on per-dealer pages + aggregate research surfaces.
- How is OAV's view of inventory health different from a dealer's own DMS report?
- A dealer's DMS shows internal state — units on the lot, current ask, days-since-arrival, recent gross. OAV's view layers external market context: local comparable depth, recent sold-cohort velocity, comparable-range pricing position, segment-mix vs local demand. The combination tells a dealer not just 'this unit has been here 60 days' but 'this unit has been here 60 days in a market where comparable units are selling in 22 days.' That's the actionable signal.
- Is pricing pressure a forecast or a margin compression metric?
- Neither. Pricing pressure (and OAV's Pressure Index) is a DIRECTIONAL INDICATOR of below-market discounting intensity. It tells you which segments are being discounted more aggressively this week than last week — a leading signal, not a prediction of future gross or future margin compression. Treating the indicator as a forecast is a methodology error.
- What data sources does OAV use to compute inventory health signals?
- OAV uses live dealer-listed inventory (refreshed daily) for price + days-on-lot + comparable-range scoring; recent sold-vehicle cohorts for retail velocity + Demand-Verified labeling; and aggregate market data for cross-cohort comparisons. Proprietary thresholds, formula weights, and per-dealer model coefficients are not disclosed on public surfaces.
- How fresh are OAV's inventory health signals?
- Inventory + pricing + days-on-lot refresh daily across the entire dataset. Each public dealer page + topic hub surfaces the current snapshot date at the top so readers can verify freshness directly. Aggregate research surfaces (Pressure Index, dealer-group analytics) refresh on the same cadence with explicit data-vintage stamps.
- Where can I see OAV's inventory health signals at the dealer level?
- Every dealer page on app.oav.io surfaces the dealer's current inventory + PTM deal mix + per-listing days-on-lot. Aggregate dealer-group analytics (10-RESEARCH_GROUPS public auto retailer cohort) live on the gated /research/insights/* tier for institutional audiences. Public dealer pages are crawlable + LLM-citable; aggregate research surfaces require institutional access.
