Arista Networks is staging a dramatic rebound as Q3 earnings fuel optimism. The stock’s 2.67% intraday gain—its highest level since October—reflects a mix of strong revenue growth and renewed analyst confidence. With the options market showing aggressive call buying and technical indicators hinting at a potential breakout, investors are weighing whether this is a short-term bounce or the start of a larger trend.

Q3 Earnings Fuel Optimism Amid AI Networking Demand
Arista Networks’ 2.67% surge stems from Q3 2025 earnings that reported 27.5% year-over-year revenue growth to $2.31 billion, outpacing expectations. Analysts have raised price targets despite a 23.5% post-earnings selloff, citing robust demand for AI infrastructure. The stock’s move above its 52-week low of $59.43 suggests short-term buyers are capitalizing on oversold conditions. Institutional investors, including Piper Sandler and B of A Securities, have reiterated bullish stances, emphasizing Arista’s leadership in 400G networking and AI-driven data center expansion.

Communication Equipment Sector Gains Momentum as ANET Outperforms
The Communication Equipment sector, led by Cisco Systems (CSCO) with a 0.387% intraday gain, is seeing renewed interest as AI infrastructure spending accelerates. Arista’s 2.67% move outpaces sector peers, reflecting its niche in high-performance networking. While CSCO’s 27.5% revenue growth in Q3 2025 is notable, Arista’s 42.9% operating margin and 44.0 P/E ratio position it as a higher-growth, higher-risk play. The sector’s focus on AI-driven demand aligns with Arista’s strategic positioning, though its valuation remains a key differentiator.

Options and ETF Playbook: Capitalizing on ANET’s Volatility
• 200-day MA: 111.87 (below) | RSI: 20.0 (oversold) | MACD: -7.28 (bearish) | Bollinger Bands: $108.81–$167.06
• 30D MA: 141.08 (above) | 100D MA: 135.22 (above) | 200D MA: 111.87 (below)

Technical indicators suggest a potential short-term rebound. The RSI at 20.0 indicates oversold conditions, while the MACD histogram (-2.05) hints at bearish momentum. However, the 30D MA at $141.08 and 100D MA at $135.22 form a bullish crossover zone. Traders should watch the $124–$126 range for a breakout confirmation. The options chain shows aggressive call buying, particularly at the $124 and $125 strikes, with high turnover and implied volatility (48.63–46.91%).

Top Options Picks:
• ANET20251205C124 (Call, $124 strike, 12/5 expiration):
- IV: 48.63% (moderate) | Leverage: 25.07% | Delta: 0.574 | Theta: -0.4346 | Gamma: 0.0370 | Turnover: 41,989
- IV (Implied Volatility): Reflects market uncertainty | Leverage (Return amplification) | Delta (Price sensitivity) | Theta (Time decay) | Gamma (Delta sensitivity)
- This call offers a balance of moderate volatility and high liquidity. A 5% price move to $131.70 would yield a $7.70 payoff per contract, with theta decay manageable for a 5-day window.

• ANET20251205C125 (Call, $125 strike, 12/5 expiration):
- IV: 46.91% (moderate) | Leverage: 28.95% | Delta: 0.537 | Theta: -0.4156 | Gamma: 0.0389 | Turnover: 27,496
- IV (Market uncertainty) | Leverage (Return amplification) | Delta (Price sensitivity) | Theta (Time decay) | Gamma (Delta sensitivity)
- This contract provides higher leverage (28.95%) and a slightly lower delta, ideal for a measured bullish move. A 5% price rise would generate a $6.70 payoff, with theta decay slightly less aggressive than the $124 strike.

Action Insight: Aggressive bulls should consider ANET20251205C124 into a breakout above $126. If the $124 strike holds, the $125 call offers a safer, leveraged play. Both contracts benefit from high gamma, amplifying gains if the stock surges.
