2 AI Stocks Wall Street Says to Sell Before They Drop 55%

Analysts imply downside of nearly 55% for Palantir (Jefferies PT $70) and up to 62% for Fastly (Citigroup PT $10) versus recent closes, driven primarily by stretched valuations. Palantir reported Q4 FY2025 revenue +70% YoY to $1.4B, $4.3B of contracts closed (+138% YoY) and a 43% GAAP net income margin, yet trades at ~84.1x forward earnings, posing valuation risk. Fastly posted FY2025 revenue +15% to $624M, non-GAAP gross margin 61% and non-GAAP net income $19.7M, but trades >70x forward earnings and faces volatile growth and rising infrastructure capex (10–12% of revenue expected in 2026), creating execution risk.

Analysis

Winners and losers are being set not by AI demand alone but by who controls routing and monetization of real‑time inference traffic. Hyperscalers and GPU suppliers (NVDA, INTC) will capture the bulk of incremental infrastructure spend; edge networking players that can monetize predictably (through integrated security, observability, or managed services) will outcompete pure transit/CDN plays as customers prefer bundled SLAs over spotty traffic‑dependent pricing.

Key risks are a valuation repricing shock and cadence-driven revenue lumpiness. In the near term (days–weeks) expect volatility around earnings and contract disclosures as a catalyst for large flows; over 3–9 months the main tail‑risk is hyperscaler consolidation of customers or a material rise in unit infrastructure costs that forces margin compression and resets multiples.

A contrarian angle: the sellside’s negative skew creates asymmetric opportunities if operational execution proves repeatable — long conviction should focus on durable contract economics (multi‑year, revenue‑share or usage floors) rather than headline growth rates. Conversely, short candidates are best sized to exploit sentiment overshoot and concentrated positioning, not structural insolvency; delta‑hedged option structures give the best tradeoff between conviction and capital efficiency.

Key Decisions for Investors

• Pair trade (3–9 month): short PLTR sized 1x vs long NVDA 0.5x. Rationale: hedge idiosyncratic AI valuation risk while capturing secular infra upside. Risk management: stop-and-reverse if PLTR prints a new multi‑quarter acceleration in contracted ARR; target 25–40% asymmetric payoff on net position.
• Directional options (earnings event, 0–30 days): buy FSLY 45–60 day put spread (OTM) to capture an earnings/traffic disappointment while limiting premium outlay. Position size small (2–3% portfolio) due to execution risk; if FSLY reports conservative guidance, expect 2–3x return on paid premium.
• Conviction long (12–24 months): accumulate NVDA on pullbacks into core infrastructure rotations; prefer call spreads to finance exposures if implied vol is elevated. Target multi-bagger upside vs single-digit drawdowns; trim into any outperformance driven by multiple expansion rather than fundamentals.
• Event hedges (3–6 months): buy protection on concentrated AI/edge longs via short‑dated index puts or single‑stock collars (use C or JEF to express macro/sentiment skew). Keep hedges active through major contract windows and regulatory/news cycles; cost should be budgeted as insurance (20–40 bps/month) rather than alpha drag.
