Scor, the French reinsurance giant, took the crown for the steepest decline in both the SBF 120 and SRD indices at the close of trading on Friday, October 31, 2025. Market analysts point to a mix of sector-wide pressures and company-specific headwinds, with trading volumes spiking as investors repositioned ahead of the weekend. Here’s a DEEP dive into what happened—and why it matters.

Why Did Scor’s Stock Plummet on October 31?
Scor’s shares nosedived by 6.2% in the final hour of trading, dragging both the SBF 120 (France’s benchmark mid-cap index) and the SRD (a Leveraged trading segment) lower. The drop wasn’t entirely unexpected—earlier in the week, JP Morgan had flagged concerns about Scor’s exposure to climate-risk reinsurance contracts. "This was a classic ‘sell first, ask questions later’ moment," noted a BTCC market strategist. TradingView data shows the stock broke through key support levels, triggering algorithmic sell-offs.
How Does This Compare to Historical Declines?
October has been brutal for European insurers. Scor’s drop marks its worst single-day performance since the 2023 cyberattack on its claims processing systems. For context: the SBF 120’s second-biggest loser that day, Vallourec, fell just 3.8%. The SRD, which amplifies gains and losses, saw Scor-related derivatives account for 12% of total volume—a spike visible on CoinMarketCap’s derivatives heatmap.
What Drove the Sell-Off?
Three factors converged:
- Reinsurance squeeze: Munich Re’s profit warning earlier that week cast doubt on the entire sector.
- Technical breakdown: The stock breached €28.40, a level that had held since August.
- Options expiry: October 31 was a quarterly "witching day," forcing hedge funds to unwind positions.
As one trader put it: "When Scor sneezes, the SRD catches a cold—and today was pneumonia."
Could This Signal a Broader Market Shift?
Possibly. Insurance stocks have been the canary in the coal mine before (remember AXA’s 2018 slide preceding the Q4 tech wreck?). But with ECB rate decisions looming, it’s too early to call this systemic. "We’re watching credit default swaps for clues," shared a BTCC analyst, pointing to data from Bloomberg Terminal.
What’s Next for Scor Investors?
All eyes are on November 7, when Scor reports Q3 earnings. The company’s Bermuda-based catastrophe bonds (a niche but telling market) have shown unusual volatility—something our team will monitor via TradingView’s insurance-sector dashboards. Short interest? Up 17% month-over-month. Dividend yield? Now at 5.3%, tempting for contrarians.
