Amcor's 13% Plunge: Earnings Woes and Sector Headwinds Spark Investor Frenzy

Summary
• Amcor (AMCR) slumps 12.97% to $8.65, its lowest since May 2025
• Q4 earnings miss estimates by 4.76%, revenues fall short by 1.76%
• Zacks Rank 4 (Sell) signals underperformance ahead

Amcor’s intraday freefall has captured market attention as the packaging giant’s Q4 results ignite a selloff. With the stock trading near its 52-week low of $8.37 and the sector reeling, investors are scrambling to parse the implications of management’s guidance and the broader industry’s struggles. The sharp drop underscores a critical inflection point for AMCR, with technical indicators and options activity hinting at a volatile near-term outlook.

Earnings Miss and Weak Guidance Trigger Sharp Selloff
Amcor’s 13% intraday collapse stems from a dual blow: earnings and revenue misses that confirm a deteriorating trend. The company reported $0.20/share earnings, 4.76% below estimates, and $5.08 billion in revenue, 1.76% shy of forecasts. This follows four consecutive quarters of missing consensus, eroding investor confidence. Compounding the issue, the Zacks Rank 4 (Sell) signals deteriorating expectations, with consensus EPS for the current fiscal year at $0.82. Management’s muted commentary on the earnings call—highlighted in the transcript—has left investors with no catalysts to offset the bearish momentum.

Paper & Packaging Sector Struggles as AMCR Drags Down Industry
The Paper & Packaging sector, already ranked in the bottom 19% of Zacks industries, faces added pressure as Amcor’s selloff amplifies sector-wide headwinds. Sector leader International Paper (IP) trades down 1.96%, reflecting broader industry weakness. Greif (GEF), another peer, is expected to report mixed results on August 27, but its 35.9% YoY earnings growth contrasts sharply with AMCR’s stagnation. The sector’s underperformance underscores structural challenges in packaging demand and margin compression, with AMCR’s struggles acting as a catalyst for renewed skepticism.

Options Playbook: Capitalizing on Volatility with AMCR20250919P9 and AMCR20251017P9
• 200-day average: $9.698 (above current price)
• RSI: 57.14 (neutral)
• MACD: 0.069 (bullish divergence)
• Bollinger Bands: Price at $8.65, below lower band of $9.24

Amcor’s technicals paint a bearish near-term picture, with key support levels at $9.39 (200D MA) and $9.66 (30D support). The RSI’s neutral reading and MACD’s positive divergence suggest potential for a rebound, but the 52-week low proximity and Zacks Sell rating tilt the odds toward further downside. For traders, the AMCR20250919P9 and AMCR20251017P9 put options offer compelling leverage.

• AMCR20250919P9: Put option with $9 strike, 0.645 delta, 33.02% IV, 0.409 gamma, 536.36% price change ratio. High gamma ensures sensitivity to price swings, while 33% IV suggests reasonable volatility. Turnover of 3,780 contracts confirms liquidity.
• AMCR20251017P9: Put option with $9 strike, 0.677 delta, 20.71% IV, 0.472 gamma, 100% price change ratio. Lower IV but higher gamma (0.472) and turnover (882) make it a safer play for a 5% downside scenario.

Payoff analysis: A 5% drop to $8.22 would yield $0.78/share for AMCR20250919P9 (90% gain) and $0.78/share for AMCR20251017P9 (88% gain). Aggressive bears should prioritize AMCR20250919P9 for its high leverage, while AMCR20251017P9 offers a more conservative entry. If $8.65 breaks, AMCR20250919P9 becomes a must-have for short-side exposure.

Backtest Amcor Stock Performance
After a -13% intraday plunge, AMCR has historically shown mixed short-to-medium-term performance. The 3-day win rate is 54.31%, the 10-day win rate is 51.01%, and the 30-day win rate is 51.38%. While there is a slight positive return in the immediate aftermath of the plunge, the overall performance is generally muted, with a maximum return of only 0.70% over 30 days.

Act Now: AMCR's Downside Risk Demands Strategic Hedging
Amcor’s 13% plunge signals a high-risk phase for investors, with technicals and fundamentals aligning for further weakness. The Zacks Sell rating, sector underperformance, and bearish options flow all point to a critical juncture. Traders should prioritize hedging with the AMCR20250919P9 put or scaling into long-dated puts like AMCR20251219P9. Meanwhile, sector leader International Paper’s 1.96% drop reinforces the need to monitor industry-wide pressures. For those with conviction, a 5% downside scenario offers a 90% return on AMCR20250919P9—making it a high-conviction play. Watch for a breakdown below $8.62 or a Zacks Rank upgrade to 3 (Hold) as key inflection points.
