Today’s session has turned into a rollercoaster for XOMA Royalty, with a staggering 21.87% intraday drop sending shockwaves through the Business Services sector. The stock’s collapse defies immediate sector-specific catalysts, yet Amazon’s rumored rush pickup service and broader e-commerce tailwinds loom large. With technical indicators flashing mixed signals and options volatility spiking, the question is no longer if the move will continue—but how traders should position for the next phase.

Amazon's Rush Pickup Service Sparks Sector Volatility
The sudden selloff in XOMA Royalty appears tethered to Amazon’s rumored expansion of its one-hour pickup service, which threatens to disrupt traditional business services models. While XOMA’s direct exposure to e-commerce logistics isn’t explicitly detailed in the provided data, the broader sector’s sensitivity to Amazon’s dominance is evident. The company’s pilot of 'Amazon Now' in Seattle and Philadelphia, coupled with same-day grocery delivery for Prime subscribers, signals a strategic pivot toward instant commerce. This shift could indirectly pressure XOMA’s business services ecosystem, particularly if Amazon’s logistics network reduces reliance on third-party platforms. The stock’s 21.87% drop mirrors the sector’s risk-off sentiment, with investors recalibrating for a potential reshuffling of market share.

Options Playbook: Capitalizing on XOMA’s Volatility
• MACD: -0.529 (bearish divergence), Signal Line: -0.808, Histogram: 0.278 (bullish crossover)
• RSI: 55.26 (neutral), Bollinger Bands: $29.61–$34.19 (price near lower band)
• 200D MA: $28.40 (price below), 30D MA: $32.39 (key resistance)

XOMA’s technical profile suggests a short-term bearish bias amid a long-term bullish trend. The stock is trading near its 200-day moving average ($28.40) and within the lower Bollinger Band ($29.61), hinting at oversold conditions. However, the MACD’s bearish divergence and RSI’s neutral stance caution against over-optimism. For traders, the $25.51 intraday low and $29.45 high define a critical range to monitor.

Backtest XOMA Royalty Stock Performance
The backtest of XOMA's performance after a -22% intraday plunge from 2022 to now shows mixed results. While the stock experienced a significant drop, it recovered moderately over various time frames. The 3-Day win rate was 52.16%, the 10-Day win rate was 53.66%, and the 30-Day win rate was 57.97%, indicating a higher probability of positive returns in the short term. The maximum return during the backtest was 7.87% over 57 days, suggesting that while the stock had strong short-term recovery capabilities, long-term gains were more modest.

XOMA’s Freefall: A High-Risk Rebound or a New Floor?
XOMA Royalty’s 21.87% drop has carved a sharp intraday trough, but the 52-week low of $18.352 remains a distant target. Technicals suggest a potential bounce near $25.51, with the 200-day MA ($28.40) acting as a critical psychological barrier. While the sector leader Accenture (ACN) has only dipped 0.33%, XOMA’s standalone volatility underscores its unique risks. Traders should watch the $29.45 intraday high for a reversal signal and the $25.51 low for a breakdown trigger. For now, the XOMA20251219P25 put offers a high-leverage, high-liquidity play on a near-term test of $25. If the stock closes below $25, the bear case gains momentum.
