Market Share Analyzer
Market share position for the group across all operating regions
Purpose
Dealer groups compete in multiple local markets simultaneously. A group can be gaining share in one city while losing it in another — without a unified view, these opposing trends mask each other and delay corrective action.
Market Share Analyzer calculates the group's make-level and segment-level market share in each location's operating region, compares it to prior periods, and identifies which markets are growing share (to reinforce) and which are losing share (to investigate).
How It Works
Execution flow. MCP tool calls are shown inline on each step.
Load all locations from group profile. Compute current and prior period date ranges per location market.
↔ Parallel Execution
get_sold_summaryPull get_sold_summary ranked by make for the current period in each location's market.
get_sold_summaryPull the same summary for the prior period to compute basis-point share change per brand per market.
Calculate share %, change in bps, and volume trend per brand per location. Flag markets with > 50 bps share loss for priority action.
MCP Tool Calls
| Tool | Calls | Purpose |
|---|---|---|
get_sold_summary | 2 per location | Current and prior period brand share |

Cost Estimate
8 share analyses/month ≈ $0.50–1
Limitations
- Share calculations reflect sold transaction data with a 1–3 day lag from the most recent complete month.
- Market geography is defined by ZIP + radius in the group profile — adjust radii if markets feel too narrow.
- Brand mapping must match MarketCheck make nomenclature exactly.
- US market only.
