Barclays identifies options trading opportunities in Nvidia, Halliburton and Snowflake

Barclays recommended call spreads on Nvidia ahead of Wednesday earnings, citing a 5.3% implied move that is roughly in line with the last two years' average and noting inverted upside skew. The bank is also constructive on Halliburton, calling energy services the best setup in 20 years on structurally higher oil and an expected multi-year capex upcycle, while it sees Snowflake as well positioned ahead of May 27 earnings with product revenue potentially reaching about $1.3 billion in Q1 and FY27 guidance upside.

Analysis

The common thread is not “earnings optionality,” it’s volatility mispricing around regime shifts. In all three names, the setup is asymmetrical because the market is paying for known event risk while underweighting second-order positioning effects: systematic call demand can force dealers short gamma, and that can extend upside if the prints are merely “good enough” rather than spectacular. The cleanest expression is that event-driven upside may be larger than implied vol suggests, but only for names where fundamental surprise can re-rate the forward multiple, not just move the stock for a day.

NVDA is the most crowded, which is usually bearish for timing but bullish for squeeze quality if guidance merely confirms AI capex durability. The contrarian angle is that the market may be focusing too much on near-term earnings magnitude and too little on whether hyperscaler demand shifts from “build” to “optimize,” which would matter more for forward revenue slope than the current quarter. If management avoids any hint of digestion in the AI infrastructure cycle, dealer hedging could amplify a multi-day drift higher after the print.

HAL is the more interesting medium-term trade because the catalyst is not one quarter but a multi-quarter re-acceleration in upstream budgets. Energy services typically lag oil by months, so the market may still be too early in repricing the duration of the capex cycle; that creates upside if activity inflects while service pricing stays sticky. The main risk is that macro-driven oil weakness or E&P discipline delays the normalization longer than consensus expects, which would cap the near-term rerating even if the structural thesis remains intact. SNOW sits in the middle: it needs evidence that AI monetization is translating into platform consolidation, not just narrative premium. If product revenue growth inflects and guidance rises together, the stock can re-rate sharply because software investors are still paying a scarcity premium for durable AI data infrastructure exposure.

Key Decisions for Investors

• Buy NVDA weekly or 1-2 week call spreads into earnings; size for a binary event and take profits on any post-print gap above the implied move, as dealer hedging can add 1-3 extra points if guidance is merely constructive.
• Go long HAL July 2026 call spreads; this is a months-long expressed view on service pricing and capex inflection, with favorable convexity if upstream budgets keep firming into 2H26.
• Use SNOW call spreads into earnings as a medium-duration upside expression on AI data-platform consolidation; target a post-guidance rerating if management raises FY27 revenue outlook, but cut quickly if the print shows product growth without forward acceleration.
• Relative-value idea: long HAL / short a lower-beta integrated oil or broad energy ETF over the next 3-6 months to isolate the capex-upcycle beneficiary from outright commodity beta.
• If you need one pure event trade, prefer NVDA over SNOW: the market is better prepared for NVDA volatility, but also more likely to create a squeeze if the guide clears a high bar without new negatives.
