Purpose

Traditional syndicated market share reports arrive 60–90 days after the fact, forcing OEM strategists to react to data that is already a full quarter stale. By the time a regional manager sees a share shift, competitors have already adjusted allocation, pricing, and incentive programs — and the window to respond has closed.

Market Share Analyzer pulls from live sold transaction data to calculate brand share, segment conquest patterns, and regional demand distribution in real time. Unlike quarterly syndicated reports, every analysis reflects the most recent complete month with basis-point precision — so allocation adjustments, incentive targeting, and competitive responses can happen in the same week the shift is detected.

How It Works

Execution flow. MCP tool calls are shown inline on each step.

Profile Load

↔ Parallel Execution

02a

Current Period Shareget_sold_summary

Calls get_sold_summary ranked by make for the current month to get sold_count per brand and total market volume.

02b

Prior Period Shareget_sold_summary

Same call for the comparison period (prior month or quarter) to compute basis-point share change per brand.

Share Math

Calculates current share %, prior share %, share change in bps, and volume change % for each brand. Flags gainers > 50 bps and losers > 50 bps.

Segment Conquest (optional)get_sold_summary

Runs additional get_sold_summary calls filtered by body_type (SUV, Sedan, Pickup, etc.) for segment-level share ranking and conquest gap analysis.

Competitive Intelligence Summary

Generates ranked share table with user's brands starred, competitor highlights, share-shift narrative, and allocation/incentive recommendations.

Limitations

US market only — requires get_sold_summary which covers US sold transactions.
Share calculations depend on sold data lag; the most recent complete month is typically available within 1–3 days of month close.
Segment conquest analysis multiplies API calls proportionally by body_type count.
Brand mapping must match MarketCheck make nomenclature exactly (e.g., 'Chevy' will not match — use 'Chevrolet').
