Cloudflare Surges 2.2% on Bullish Momentum as Options Market Lights Up – What’s Fueling the Rally?

Summary
• Cloudflare (NET) trades at $226.23, up 2.2% with a day high of $229.53 and low of $220.51
• RSI hits 76.3, signaling overbought territory, while MACD (6.36) and bullish Kline patterns amplify momentum
• Sector leader Akamai (AKAM) declines 0.95%, highlighting divergent sector dynamics

Cloudflare’s sharp intraday rally defies a weak sector backdrop, driven by technical buying and surging options activity. With the stock nearing its 52-week high of $230.10 and a 76.3 RSI reading, short-term traders are scrambling to position ahead of the September 19 expiry. The options chain reveals aggressive bullish bets, particularly in out-of-the-money calls, as volatility metrics and leverage ratios spike.
Technical Bullishness and Options Volatility Drive Sharp Rally
The surge in Cloudflare’s stock is fueled by a confluence of technical and options-driven factors. A short-term bullish Kline pattern, combined with a MACD crossover above the signal line (6.36 vs. 4.73), has ignited momentum. The RSI’s 76.3 reading—close to overbought territory—suggests aggressive buying pressure. Meanwhile, the options market amplifies this trend: 123,894 contracts for the $225 call (NET20250919C225) traded at 50.25% implied volatility, with a 42.16% price change ratio. This indicates institutional positioning for a continuation of the rally ahead of the September 19 expiry.

Internet Services Sector Splits as Cloudflare Defies Peers
While Cloudflare’s stock surges, its sector leader Akamai (AKAM) declines 0.95%, underscoring divergent dynamics within the Internet Services and Infrastructure space. The sector’s mixed performance highlights Cloudflare’s unique technical strength, as its 2.2% intraday gain contrasts with broader sector caution. This divergence suggests that Cloudflare’s rally is driven by specific technical and options-driven factors rather than macro-sector tailwinds.

Capitalizing on Bullish Momentum: ETFs and Options for the Short-Term Grind
• 200-day average: $151.12 (far below current price)
• RSI: 76.3 (overbought)
• MACD: 6.36 (bullish)
• Bollinger Bands: $227.93 (upper), $207.37 (middle), $186.79 (lower)

Cloudflare’s technicals scream continuation of the rally. Key levels to watch include the $227.93 upper Bollinger Band and the 52-week high of $230.10. The options market reinforces this view, with high-liquidity calls offering leveraged exposure. Two top picks from the chain:

• NET20250919C230 (Call, $230 strike, 51.91% IV, 60.23% leverage ratio, delta 0.3979, theta -1.2288, gamma 0.0281, turnover 82,273): This contract balances leverage (60.23%) with moderate delta (0.40), making it ideal for a 5% upside scenario. A 5% move to $237.54 would yield a $7.54 payoff per share, with high gamma (0.0281) amplifying gains as the stock rises.
• NET20250919C232.5 (Call, $232.5 strike, 49.85% IV, 83.66% leverage ratio, delta 0.3238, theta -1.0455, gamma 0.0273, turnover 7,849): The 83.66% leverage ratio offers explosive potential if the stock breaks $232.50. A 5% move to $237.54 would generate a $5.04 payoff, with strong gamma (0.0273) ensuring rapid premium acceleration.

Aggressive bulls should target the NET20250919C230 for a controlled leveraged play, while the NET20250919C232.5 suits high-risk, high-reward scenarios. Both contracts benefit from elevated implied volatility and liquidity, ensuring smooth entry/exit.

Break $227.93 and the Bull Case Intensifies – Act Now
Cloudflare’s rally is technically robust, with RSI overbought and MACD bullish, but the $227.93 upper Bollinger Band and 52-week high of $230.10 remain critical hurdles. The options market’s aggressive call buying—particularly in the $230–$232.50 range—suggests conviction in a continuation. However, sector leader Akamai’s 0.95% decline warns of potential macro headwinds. Investors should prioritize the NET20250919C230 for a leveraged, high-gamma play if the stock breaks $227.93. Watch for a breakdown below $220 to trigger short-term profit-taking.
