INCY Plummets 6.87%: What's Behind the Sudden Sell-Off?

Summary
• Incyte’s stock nosedives to an intraday low of $84.02, a 6.87% drop from its 2025-10-28 open of $92.25.
• The company raised its 2025 sales guidance to $4.23–$4.32 billion but fell short of Wall Street’s $4.84 billion projection.
• Technical indicators signal bearish momentum, with RSI at 67.25 and MACD histogram surging to 0.57.

INCY’s sharp selloff has sent shockwaves through the biotech sector, with traders scrambling to decipher the catalyst. The stock’s collapse follows a mixed earnings report and a guidance update that failed to satisfy bullish expectations. With the price breaching key support levels and options volatility spiking, the question now is whether this is a short-term correction or a deeper re-rating of the stock.

2025 Guidance Misses Hype, Sparking Investor Exodus
INCY’s 6.87% intraday plunge stems from a disconnect between its raised 2025 sales guidance and Wall Street’s expectations. While the company projected $4.23–$4.32 billion in full-year sales, analysts had forecast $4.84 billion. The shortfall, coupled with a 5.10% post-earnings decline, triggered a wave of profit-taking and short-covering. The stock’s sharp drop also reflects skepticism about the sustainability of Jakafi’s growth amid competitive pressures and pricing headwinds. The 52-week high of $93.17 now looms as a critical psychological barrier.

Biotech Sector Mixed as Amgen Trails Slightly
The biotech sector remains fragmented, with Amgen (AMGN) down 0.26% despite its broader industry context. While INCY’s selloff is product-specific, the sector’s cautious tone—driven by regulatory uncertainties and earnings volatility—has amplified INCY’s decline. However, Amgen’s resilience highlights the disparity in market sentiment between large-cap and mid-cap biotechs.

Options Playbook: Capitalizing on Volatility with Strategic Puts
• MACD: 1.59 (bullish divergence), Signal Line: 1.02, Histogram: 0.57 (momentum waning)
• RSI: 67.25 (overbought but bearish reversal likely)
• Bollinger Bands: Price at $86.69, below the middle band of $87.09
• 200D MA: $72.35 (far below current price), 30D MA: $86.16 (near-term support)

The technical setup suggests a bearish continuation, with key support at $84.63 (30D) and $68.06 (200D). The 200D MA remains a critical long-term floor. For options, focus on high-leverage puts with moderate delta and strong gamma to capitalize on the expected volatility. The sector’s mixed performance and INCY’s earnings-driven selloff justify a cautious short-term stance.

INCY’s Crucial Crossroads: Watch for $84.63 Support
INCY’s selloff reflects a mix of earnings underperformance and sector-wide caution. The stock’s near-term fate hinges on its ability to hold the 30D support at $84.63. A breakdown below this level could trigger a test of the 200D MA at $68.06, while a rebound above $87.09 may signal a short-term bounce. Investors should monitor Amgen’s (-0.26%) performance as a sector barometer. For now, the put options highlighted offer a strategic edge in a volatile environment. Act now: Short-side traders should target INCY20251121P90 if $86.69 fails to hold.
