Summary
• Chubb (CB) rockets 3.81% to $307.85, hitting its 52-week high of $307.92
• Insurance Insider report claims Chubb made informal takeover approach to AIG, denied by the company
• Options frenzy: 2025-12-19 305C sees 60,476 shares traded, 260.83% price surge
• Analysts split: Cantor Fitzgerald calls AIG deal 'very unlikely,' while Bank of America sees 'sense' in a merger

Chubb’s intraday rally has ignited a firestorm of speculation, driven by conflicting signals from the company and analysts. The stock’s 3.81% surge to $307.85—a 52-week high—coincides with a rumored but denied AIG takeover approach. With options volatility spiking and sector peers like Allstate (ALL) rising 2.98%, the market is betting on a resolution to the uncertainty. The key question: Will Chubb’s bullish momentum hold, or is this a short-lived spike?

AIG Takeover Rumors Ignite Chubb’s Bullish Surge
The surge in Chubb’s stock is directly tied to a report from Insurance Insider, which claimed Chubb made an informal takeover approach to AIG. While Chubb’s spokesperson denied making an 'offer,' the ambiguity has fueled speculation. Analysts are divided: Cantor Fitzgerald calls the deal 'very unlikely,' citing AIG’s 'not for sale' stance, while Bank of America argues a merger 'would make sense.' The stock’s 3.81% gain reflects investor optimism that Chubb’s valuation (12.8x P/E) and AIG’s strategic assets could create value, even if a deal remains unconfirmed. The options market has priced in this volatility, with 2025-12-19 305C options surging 260.83% as traders bet on a breakout.

Insurance Sector Mixed as Chubb Outpaces Peers
The broader insurance sector shows mixed signals. While Chubb’s rally is tied to M&A speculation, peers like Allstate (ALL) rose 2.98% on broader market optimism. However, the sector faces headwinds: a first-half P/C underwriting loss of $24.5 billion and regulatory scrutiny over litigation funding. Chubb’s 3.81% gain outpaces the sector’s average, reflecting its unique position as a takeover target. AIG’s 2.81% rise suggests market skepticism about its 'not for sale' stance, but its valuation (P/E of 14.4) remains a hurdle for any bid.

Options Playbook: Leverage Gamma and Theta for Chubb’s Volatility
• MACD: 3.02 (above signal line 3.38), RSI: 55.01 (neutral), Bollinger Bands: Price at $307.85 (above upper band $299.63)
• 200-day MA: $283.90 (below current price), Support/Resistance: 200D range $277.66–$278.39 (far below)

Chubb’s technicals suggest a short-term bullish trend with a bearish engulfing pattern, indicating potential consolidation. Key levels to watch: $305 (psychological hurdle) and $310 (next resistance). The 52-week high of $307.92 is critical; a break above could trigger a retest of $315. For options, focus on contracts with high gamma and theta to capitalize on volatility decay.

Backtest Chubb Stock Performance
The backtest of CB's performance after a 4% intraday surge from 2022 to the present reveals mixed results. While the 3-day and 30-day win rates are high at 100%, the 10-day win rate is 0%, indicating that although CB showed strong short-term gains, it failed to maintain this momentum over longer periods. The maximum return during the backtest was 13.32%, which occurred on day 56, suggesting that while CB had strong potential for immediate gains, these were not consistently sustained.

Chubb’s M&A Drama: Time to Ride the Wave or Exit Before the Storm?
Chubb’s 3.81% surge hinges on the unresolved AIG takeover speculation. While the company denies making an offer, the options market has priced in a 260.83% surge in 305C contracts, reflecting high conviction in a near-term resolution. Technically, the stock is testing its 52-week high, with RSI at 55.01 and MACD diverging, suggesting potential consolidation. For now, the bullish momentum is intact, but a breakdown below $300 could trigger a retest of the 200-day MA at $283.90. Investors should monitor AIG’s stance and regulatory developments. Meanwhile, Allstate (ALL) rose 2.98%, signaling sector-wide optimism. Act now: Buy CB20251219C305 if $305 closes above, or short CB20251219P295 if the rally falters.
