31Debt ceiling / CR events since 2010 — each triggers volatility
Choose your depth. The data doesn't change — just the explanation.
Some companies get almost all their money from the government. When the government almost runs out of money (debt ceiling fights), those companies' stocks go crazy — bouncing up and down way more than normal companies. You can predict which companies will get shaky just by looking at how much government money they get.
Defense contractors, IT services firms, and healthcare companies that depend on federal contracts for more than 40% of their revenue are extremely sensitive to government budget uncertainty. During the 31 debt ceiling and continuing resolution events since 2010, these high-dependency companies showed beta (a measure of stock volatility) 2.3 times higher than similar companies without federal dependency. This creates a tradeable pattern.
Government Dependency Score (GDS) = federal contract revenue ÷ total revenue (from SEC 10-K filings cross-referenced with USAspending). Companies with GDS > 0.40 show significantly elevated beta during budget uncertainty windows (14 days pre-event through resolution date). Beta is measured against CBOE VIX-adjusted sector ETF. The 2.3× figure is median; 90th percentile reaches 3.8×. Continuing resolution uncertainty (partial-year budgets) creates larger spikes than debt ceiling events due to direct contract modification exposure.

The Most Federal-Dependent Public Companies
These companies derive the largest share of their revenue from federal contracts. Their stock volatility during budget events is directly proportional to their dependency score.

Budget Events Timeline: Every Spike Is Predictable
31 debt ceiling and continuing resolution events since 2010. Every single one produced measurable volatility spikes in high-GDS companies — before the event resolved.

⚠️ The Continuing Resolution Trap
CRs (continuing resolutions) are actually more dangerous than debt ceiling fights for contractors. A CR freezes new contract awards and modifications for the CR period. Companies mid-negotiation on large contracts face immediate cash flow uncertainty. Booz Allen and SAIC's stock standard deviation doubles during multi-month CRs — completely predictable from contract renewal timing in their SEC filings.
