NVDA Deep-ITM Sell Put Rolling Case

Rebuilding a positive-expectancy setup through Greek-based gates, rolling execution, and disciplined risk controls

After NVDA fell 11.3%, an existing $780 put became deep in the money with a delta of -0.82 and almost no theta advantage. A rule-based roll replaced the position with a $720 put, which ultimately expired safely with all premium collected.

NVDA Deep-ITM Sell Put Rolling Case

This case defines a four-stage operating framework for deep-ITM short puts: environment detection, risk filtering, position restructuring, and dynamic defense with review. With NVDA at $692, theta near $0.08 per day, and absolute delta at 0.82, holding the position was increasingly a bet on a rebound rather than a theta-harvesting trade. The $780 put was closed and replaced with a $720 put extending expiry to June 28, 2026. NVDA later rebounded to $748, allowing the new position to expire safely with the full $1,840 premium retained.

Highlights & Metrics

  • Trigger: absolute delta of 0.82 and theta of only $0.08 per day exposed the position to directional risk
  • Rolling structure: closed the $780 put and sold a $720 put with a later expiration date
  • Net restructuring cost: $8,730 to close, less $1,840 in new premium, for a realized net cost of $6,890
  • Live outcome: NVDA rebounded to $748 and the replacement position expired safely with all premium collected

Earnings-Season Options Case: Navigating IV Crush

Earnings uncertainty typically lifts implied volatility, allowing sellers to collect larger premiums, while the post-report IV Crush can rapidly reduce option prices. The framework applies four rules: cut exposure by one-third three days before earnings, avoid opening positions one day before the release, wait 24 hours after the announcement, and close favorable Sell Put positions promptly as IV falls. The live trades used short puts at GOOG $370 and AAPL $270, entered while IV was elevated and exited after volatility declined, producing combined net profits of $1,599 in two days.

Highlights & Metrics

  • GOOG SP $370: +$690 net profit over 2 days
  • AAPL SP $270: +$909 net profit over 2 days
  • $1,599 combined profit across two 2-day trades
  • Four controls: de-risk, delay entries, wait 24 hours, and monetize IV Crush

SpaceX's $60B Cursor Acquisition: Compute Meets the Developer Distribution Layer

The strategic rationale begins with Cursor's compute constraints. SpaceX brings Colossus, which the company says delivers the equivalent of one million Nvidia H100 GPUs, while Cursor supplies a rapidly scaling AI-native IDE, proprietary workflow context, and access to enterprise developers. An April 2026 option agreement established price and exclusivity before SpaceX's IPO; exercising it immediately afterward demonstrates a structured execution model for large, strategically coupled technology acquisitions.

Highlights & Metrics

  • $60B all-stock transaction expected to close in Q3 2026
  • Cursor's valuation rose more than 24x in 18 months, from $2.5B to $60B
  • Cursor surpassed $100M in ARR by November 2025 and was adopted by over half of Fortune 500 companies
  • Colossus provides an NVIDIA H100-equivalent compute base to address Cursor's reinforcement-learning bottleneck

Its agent architecture autonomously invokes tools such as search, code interpretation, data analysis, and calculation to complete multi-step tasks. Users can move from image analysis to report creation and presentation outlines without changing platforms, lowering workflow friction and increasing automation.

Highlights & Metrics

  • Native Chinese model design improves contextual and cultural understanding
  • Images, documents, audio, video, and text share one conversational context
  • Supports document summarization, extraction, analysis, and format conversion
  • Agents autonomously coordinate dozens of tools for complex, multi-step tasks

2026 H1 Options Seller Survival Report: 13 Trades and $1,219 Net Profit

Across 13 options trades in 2026 H1, the strategy collected $224,924 in premiums and paid $234,775 at closure, producing $1,219 in realized profit. The three strongest trades shared a 6% to 10% margin of safety and sufficient holding time, while the worst losses involved strikes too close to spot, oversized positions, and delayed stops. Following a $9,926 loss in May, the strategy adopted five controls: at least 8% margin of safety, three contracts per trade, AAPL diversification, a monthly stop after a loss above $5,000, and a mandatory decision journal for every entry.

Highlights & Metrics

  • 13 trades, 12 winners, and a 92.3% win rate
  • $1,219 in realized profit, approximately TWD 38,497
  • $224,924 in total premium income with a 1.5% average margin ROI
  • A $9,926 loss in May demonstrated the need for strict sizing and stop discipline

Waller’s Debut: A Three-Scenario Fed Policy Trading Framework

Built around Waller’s first major speech as a Fed governor, the framework follows a three-stage process: positioning before the event, real-time interpretation during delivery, and scenario validation afterward. Three communication layers—rate-path phrasing, inflation language, and employment risks—are mapped to expected moves in the dollar, US equities, two-year Treasury yields, and gold. Position limits, stop-loss rules, and wait-for-confirmation conditions are defined for high-duration technology stocks and long-duration bonds to reduce event-driven whipsaw exposure.

Highlights & Metrics

  • Three-layer forward-guidance decoding framework
  • Three policy scenarios: dovish, neutral, and hawkish
  • Four mapped assets: USD, equities, Treasuries, and gold

Claude Sonnet 5 Agentic AI Case

This case analyzes Sonnet 5's product positioning and enterprise deployment strategy. The model reaches 80.4% on Terminal-Bench 2.1, improving by 13.4 percentage points over Sonnet 4.6. It scores 57.4% on Humanity's Last Exam with tools, only 0.5 percentage points below Opus 4.8, and records 1618 on GDPval-AA v2 versus 1615 for Opus 4.8. Rather than chasing benchmark leadership alone, the design places reliable coding, terminal-operation, and knowledge-work capabilities into a lower-cost model tier, enabling enterprises to route workloads by complexity and scale automation.

Highlights & Metrics

  • 80.4% on Terminal-Bench 2.1, a 13.4 percentage-point gain over Sonnet 4.6
  • 57.4% on Humanity's Last Exam with tools, only 0.5 percentage points below Opus 4.8

Quadruple Witching × Fed Decision × SOX Selloff: An Options Risk-Control Case

The case studies the interaction of three market forces: concentrated expiration and rollover flows, uncertainty surrounding the Federal Reserve's policy decision, and semiconductor-position reduction. The framework tracks trading volume, liquidity, implied volatility, dealer gamma, directional exposure, and overnight risk. It also evaluates whether SOX weakness reflects doubts about AI capital-spending returns, export controls, or broader multiple compression, with predefined controls for sizing, staged execution, profit-taking, and downside protection.

Highlights & Metrics

  • Quadruple-witching volume typically reaches roughly 1.5–2 times a normal session, with the sharpest liquidity shocks near the close
  • Monitors FOMC implied volatility, futures rollover behavior, and dealer gamma-driven hedging demand
  • Uses SOX and Nasdaq relative strength to assess whether semiconductor weakness risks spreading into broader technology de-rating
  • Applies shorter holding periods, capped event exposure, staged adjustments, and predefined stop-loss rules

From the Mythos Export Ban to the Max 20x Class Action: Inside the AI Compute Billing Black Box

This report reconstructs two compounding events. Part one dissects the unprecedented U.S. export-control order that forced Anthropic to sever global access to Fable 5 and Mythos 5 after Amazon researchers demonstrated a jailbreak capable of extracting exploit-ready vulnerability intelligence and PoC blueprints — and the 160-signature open letter from cybersecurity leaders (including Alex Stamos and Bruce Schneier) that condemned the move as self-disarmament. Part two unpacks software engineer Karl Kahn's putative class action in the Northern District of California, scrutinizing how '20x' was marketed as a token-volume multiplier versus Anthropic's defense that it denotes compute speed and priority queuing — a gap that defines the true 'billing black box' of agentic-coding workloads.

Highlights & Metrics

  • Minute-by-minute timeline of the Mythos ban order issued at 17:21 ET on June 12, 2026
  • Forensic breakdown of the Max 20x lawsuit's '20x' marketing-vs-implementation dispute

Fable 5 vs. The 18-Day Ban: Anatomy of the First U.S. Export Control on a Frontier AI Model

On June 13, 2025, the U.S. Department of Commerce issued an export control order requiring Anthropic to pull Fable 5 and Mythos 5 worldwide, citing national security risks — marking the first time a government directly froze a private AI company's flagship model. Eighteen days later, Commerce Secretary Howard Lutnick personally signed the withdrawal. Fable 5 returned globally on July 2 (U.S. Eastern), but the unban came with explicit conditions: a 50% weekly throughput cap until July 7, Pro-tier access only, deployment of a new proactive jailbreak-detection classifier, and a commitment to co-author the federal jailbreak evaluation framework. Fable 5 and Mythos 5 share the same base architecture but differ in safety guardrails — Mythos 5 is gated behind Project Glasswing, accessible only to 11 vetted cyber-defense and critical-infrastructure partners including AWS, Apple, CrowdStrike, Google, and Microsoft. Both models are priced at $10/$50 per million input/output tokens, roughly 2x Claude Opus 4.8.

Highlights & Metrics

  • 18 days: full lifecycle from ban issuance to Lutnick's signed reversal
  • First-of-its-kind: the first government-mandated shutdown of a private frontier model
  • 50% weekly cap + Pro-only access: the throughput and tier restrictions attached to the unban
  • Dual-track design: Fable 5 (public) vs. Mythos 5 (Project Glasswing-only) as a guardrail-differentiated architecture

The Options Landlord: A Sell Put Strategy with 92.3% Win Rate

The author uses the 'landlord collecting rent' analogy to explain Sell Put: pick a stock you'd happily own at a discount, sell a put at that strike price, and collect premium as theta decays in your favor. Put selling accounts for 11 of 13 trades, generating high-probability small wins that compound into steady income. The article walks through all four options quadrants, clarifies why time is the seller's ally, and transparently shares the single $6,060 loss that nearly wiped out all profits — distilling three iron rules: strike-price-as-stock-picking, position sizing, and pre-expiration decision-making. Ideal for beginners exploring options-selling strategies on US equities.

Highlights & Metrics

  • 13 completed trades with 92.3% win rate (12 wins / 1 loss)
  • Realized net P&L: +$1,219 USD (~38,497 TWD)
  • Sell Put dominates the book: 11 out of 13 trades
