Arista Networks is surging on a perfect storm of institutional buying, earnings outperformance, and AI infrastructure tailwinds. With Voya's massive stake increase and Q3 results exceeding expectations, the stock is testing key technical levels. Traders are now weighing whether this momentum will sustain or if profit-taking could trigger a pullback.

Institutional Buying and Earnings Outperformance Ignite Rally
Arista Networks' 6.13% intraday surge is driven by three key catalysts: Voya Investment Management's 29.8% stake increase to 3.778M shares, Q3 earnings beating estimates by $0.03 with 27.5% revenue growth, and a $163.56 average analyst price target. The stock's 52-week high of $164.94 remains a psychological barrier, but the 39.7% net margin and 47.4 P/E ratio suggest strong fundamentals. Institutional ownership at 82.47% indicates long-term conviction despite insider selling of $21.7M in the last quarter.

Communication Equipment Sector Gains Momentum as ANET Outperforms
The Communication Equipment sector is seeing mixed momentum, with Cisco Systems (CSCO) rising 2.44% as the sector leader. Arista's 6.13% gain outpaces the sector average, driven by its AI infrastructure focus. While CSCO's growth is steady, ANET's 27.5% YoY revenue growth and 39.7% net margin position it as a high-conviction play in the AI networking space. The sector's $156.98B market cap for ANET reflects its premium valuation compared to peers.

Options Playbook: Capitalizing on ANET's Volatility and Technical Setup
• 200-day MA: $114.20 (below) • 50-day MA: $128.18 (below) • RSI: 39.05 (oversold) • MACD: -2.71 (bearish) • Bollinger Bands: $118.38–$134.87

ANET is trading near its 200-day MA with oversold RSI, suggesting potential for a rebound. The 52-week high at $164.94 remains a critical resistance level. For leveraged exposure, consider QQQ (NMS:QQQ) as a tech ETF proxy. The options chain shows high liquidity in the 130–138 strike range with implied volatility between 30%–45%.

Top Call Option: ANET20251226C130
• Strike: $130 • Expiry: 12/26 • IV: 35.83% • Delta: 0.635 • Theta: -0.576 • Gamma: 0.0536 • Turnover: 399,744
IV: High volatility suggests strong move potential • Delta: 63.5% sensitivity to price • Theta: High time decay • Gamma: Strong sensitivity to price changes • Turnover: High liquidity
This contract offers 280.91% leverage with a 63.5% delta, ideal for a bullish breakout above $130. If ANET closes above $130 by 12/26, the payoff would be $2.255 per share (5% upside from $132.255).

Top Put Option: ANET20251226P125
• Strike: $125 • Expiry: 12/26 • IV: 36.58% • Delta: -0.144 • Theta: -0.0008 • Gamma: 0.0317 • Turnover: 18,016
IV: High volatility • Delta: 14.4% downside sensitivity • Theta: Minimal time decay • Gamma: Moderate sensitivity • Turnover: Sufficient liquidity
Use this for downside protection if ANET fails to break above $134.87 (Bollinger Upper Band). A 5% downside to $125.64 would yield $0.64 per share.

Aggressive bulls should consider ANET20251226C130 into a break above $134.87 (Bollinger Upper Band). Conservative traders may use ANET20251226P125 as a hedge against a pullback.

Backtest Arista Networks Stock Performance
The backtest of ANET's performance after an intraday surge of at least 6% from 2022 to the present shows favorable short-to-medium-term gains, highlighting the stock's potential for positive movement following strong price days. However, the maximum return during the backtest period was only 10.58% over 30 days, indicating that while ANET can deliver decent returns on moderate time frames, it may not consistently achieve high returns over extended periods.

ANET's AI Infrastructure Play: Time to Ride the Wave or Secure Profits?
Arista Networks' 6.13% surge reflects strong institutional backing and AI infrastructure demand, but the 52-week high at $164.94 remains a critical test. With Voya's $550M stake and Q3 outperformance, the stock is well-positioned for continued growth. However, the 39.7% net margin and 47.4 P/E ratio suggest valuation risks. Watch for a breakout above $134.87 (Bollinger Upper Band) or a breakdown below $126.62 (200-day MA). The sector leader CSCO is up 2.44%, signaling broader industry strength. For traders, ANET20251226C130 offers high leverage if the $130 level holds.
