Summary
• Alnylam Pharmaceuticals (ALNY) surges 2.97% to $462.52, hitting an intraday high of $463.75
• Institutional investors add 1,334 shares via Vise Technologies, while insiders offload $37.5M in shares

Alnylam Pharmaceuticals is trading at its highest level in months, driven by a mix of institutional accumulation, analyst optimism, and a bullish technical setup. The stock’s 2.97% gain on the session reflects a confluence of factors: fresh institutional buying, insider selling that may signal confidence in the stock’s performance, and a string of analyst upgrades. With the 52-week high at $495.55 still in reach, traders are weighing whether this rally is a breakout or a correction within a broader uptrend.

Institutional Accumulation and Analyst Optimism Fuel ALNY’s Surge
Alnylam’s intraday rally is underpinned by a surge in institutional buying, including a $435,000 position by Vise Technologies and a 11.8% stake increase by Allworth Financial. These moves signal confidence in the stock’s long-term potential, particularly as the company’s AMVUTTRA therapy gains traction inATTR-CM treatment. Meanwhile, insider selling—while notable—has not dampened investor sentiment, as executives like Jeffrey Poulton and Kevin Fitzgerald offloaded shares at $452.05, a price still 2.7% below the current level. Analysts have amplified the bullish case, with Bank of America raising its target to $520 and Morgan Stanley to $475, reflecting optimism about Alnylam’s pipeline and commercial execution. The stock’s 2.97% gain aligns with a broader sector rebound in biotech, though ALNY’s move is more directly tied to its fundamentals than sector-wide trends.

Options Playbook: Leveraging ALNY’s Bullish Momentum with High-Leverage Calls
• 200-day MA: $344.66 (well below current price); RSI: 37.40 (oversold territory)
• Bollinger Bands: Upper at $491.93, Middle at $456.20, Lower at $420.47 (current price near middle band)
• MACD: -3.56 (bearish divergence), but RSI suggests potential reversal

Alnylam’s technicals present a compelling case for aggressive bullish positioning. The stock is trading near its 50-day MA of $458.80 and has broken above the lower Bollinger Band, suggesting a potential continuation of the rally. The RSI at 37.40 indicates oversold conditions, which could attract algorithmic buying. For options traders, the 470C and 460C contracts stand out due to their high leverage ratios and moderate deltas. Here’s a breakdown of the top picks:
