CVS Health Plummets 4.38% Amid $6B Charge Fallout—Is the Sell-Off a Buying Opportunity?

Summary
• CVS Health (CVS) slumps 4.38% to $77.07, its lowest since October 2023
• Q3 loss of $4B driven by $6B Oak Street Health write-down
• Sector leader Johnson & Johnson (JNJ) rallies 1.29% amid pharma sector volatility
• Options frenzy: 2025-11-07 expiry sees $233,481 turnover in 77-strike call options

CVS Health’s 4.38% intraday plunge has ignited a firestorm in the pharma sector, with the stock trading near its 52-week low of $43.56. The selloff follows a $6B charge to scale back its Oak Street Health clinics, overshadowing a $102.9B revenue beat. As the stock tests critical support levels, traders are scrambling to position for a potential rebound or further decline.

CVS's $6B Oak Street Charge Sparks Earnings Shockwave
CVS Health’s 4.38% drop stems from a $6B non-cash charge to scale back its Oak Street Health clinics, a business acquired in 2022. Despite a 8% revenue surge to $102.9B and a $1.60 adjusted EPS beat, the charge wiped out $4B in Q3 profits. The move signals a strategic retreat from high-cost healthcare services, raising concerns about long-term growth. Analysts had expected $1.37 EPS, but the charge’s magnitude—equivalent to 7.5% of the company’s market cap—triggered a sharp repricing of risk.

Pharma Sector Splits as J&J Rises, CVS Crumbles on Earnings Shock
While the broader pharmaceutical sector remains mixed, Johnson & Johnson (JNJ) defied the sell-off, rising 1.29% as its diversified healthcare portfolio and strong R&D pipeline offset sector-wide jitters. CVS’s 4.38% drop contrasts sharply with JNJ’s resilience, highlighting divergent earnings narratives. The pharma sector’s 0.5% intraday gain underscores market confidence in long-term fundamentals, but CVS’s charge has created a short-term vacuum in investor sentiment.

Options Playbook: 77-Strike Puts and 75-Strike Puts for Short-Term Volatility
• 200-day MA: 66.95 (below) • 30D MA: 78.48 (above) • RSI: 66.67 (neutral) • MACD: 1.87 (bearish divergence) • Bollinger Bands: 75.31–84.58 (current price at 77.07, near lower band)

CVS is trading at a 7.5% discount to its 30D MA of 78.48, with RSI hovering near neutral territory. The 200-day MA at 66.95 offers a critical floor, while the 75.31 lower Bollinger Band aligns with key support at 76.83. Short-term volatility is amplified by the 29.54% IV in the 77-strike put (CVS20251107P77) and 22.85% IV in the 75-strike put (CVS20251107P75).

• CVS20251107P77 (Put, $77 strike, 2025-11-07 expiry):
- IV: 29.54% (moderate)
- LVR: 53.06% (high leverage)
- Delta: -0.496 (moderate sensitivity)
- Theta: -0.0366 (rapid time decay)
- Gamma: 0.1117 (high sensitivity to price swings)
- Turnover: $36,280 (liquid)
- Payoff at 5% downside (73.22): $3.85 per contract
- This put offers asymmetric upside if the stock breaks below 75.31, with high gamma amplifying gains in a volatile environment.

• CVS20251107P75 (Put, $75 strike, 2025-11-07 expiry):
- IV: 22.85% (low)
- LVR: 202.45% (extreme leverage)
- Delta: -0.232 (moderate sensitivity)
- Theta: -0.0283 (moderate decay)
- Gamma: 0.1105 (high sensitivity)
- Turnover: $3,195 (liquid)
- Payoff at 5% downside (73.22): $1.78 per contract
- The 75-strike put’s 202.45% leverage ratio makes it a high-risk/high-reward play for aggressive bears.

Aggressive bears should prioritize the 77-strike put for its balance of leverage and liquidity. If the stock breaks below 75.31, the 75-strike put could explode in value. However, a rebound above 78.48 would invalidate the bearish case.

Backtest CVS Health Stock Performance
Here is the event-study you requested. CVS has experienced 21 daily plunges of –4 % or worse since January 2022. The pattern that emerges is classic mean-reversion:• Over the first two weeks the stock continues to drift lower, but by Day 19 the average position has swung to a +3.6 % gain and the win-rate climbs above two-thirds. • Between Day 19 – 30 the positive excess return (vs. S&P 500) becomes statistically significant, peaking around +5 % by Day 29. • Risk-reward: drawdowns are front-loaded (worst within 5–7 days), while the upside progressively dominates after the second week. Assumptions automatically filled:1. Intraday plunge was proxied with the daily close-to-previous-close move (data granularity available). 2. A 30-day post-event window was used—the most common horizon for short-term mean-reversion studies; we can extend/shorten it if needed. 3.

Act Now: CVS at Key Support—Bullish or Bearish Play?
CVS’s 4.38% drop has created a critical juncture at 76.83–77.01 support. A break below 75.31 would validate the bearish case, while a rebound above 78.48 could trigger a short-covering rally. The sector leader Johnson & Johnson’s 1.29% gain suggests pharma fundamentals remain intact, but CVS’s charge has created a short-term void. Traders should monitor the 77-strike put for volatility and the 75-strike put for extreme leverage. Watch for a $75.31 breakdown or a reversal above 78.48 to dictate next steps.
