Purpose

Market share changes are leading indicators of revenue trajectory. An OEM gaining 50+ bps of market share in a quarter will show up in revenue outperformance 60–90 days later — by which time the move is already priced in. Real-time share data provides the edge.

Market Share Analyzer computes brand share aggregated to the ticker level, compares to prior periods, and delivers BULLISH/BEARISH/NEUTRAL/CAUTION signals per OEM ticker. Includes segment conquest analysis and dealer group share signals for retail tickers.

How It Works

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

↔ Parallel Execution

01a

Current Period Shareget_sold_summary

Calls get_sold_summary ranked by make for current period. Extracts sold_count per brand, total market volume.

01b

Prior Period Shareget_sold_summary

Same call for prior period. Computes share %, share change in bps, and volume change % per brand. Aggregates to ticker.

Signal Assignment

BULLISH: gaining >+30 bps AND volume up. BEARISH: losing >-30 bps AND volume down. CAUTION: share gaining but volume down. NEUTRAL: within ±30 bps.

Segment Conquest (optional)get_sold_summary

Calls get_sold_summary by body_type to identify which tickers are gaining/losing share in high-value segments (SUV, Pickup). Multiplies calls by segment count.

Limitations

US market only.
Share calculations depend on sold data lag — most recent complete month available within 1–3 days of month close.
100 bps of national share ≈ 15,000–17,000 annual units — always contextualize share changes in volume terms.
Brand name must match MarketCheck nomenclature exactly (use 'Chevrolet' not 'Chevy').
