Berkshire Hathaway shares have flatlined over the past two weeks even as the S&P 500 rallied to all-time highs, marking a rare divergence between the conglomerate and the broader market. The underperformance reflects Buffett's well-documented reluctance to deploy capital at current valuations, with Berkshire sitting on record cash reserves.

Iran has restricted the Strait of Hormuz again and fired on a tanker as peace negotiations stall, contradicting Trump's claims of "good news" on a bilateral nuclear deal. The move signals Tehran is willing to weaponize energy chokepoints to extract concessions, even as Trump administration officials suggest a joint nuclear material recovery agreement is imminent.

Oil prices remain elevated on supply disruption risk; WTI and Brent are sensitive to any sustained Hormuz closure. The U.S. energy independence narrative—bolstered by domestic production and LNG exports—provides a buffer, but prolonged Iranian aggression could push crude toward $4+ per gallon retail, pressuring consumer discretionary spending and airline margins.

The Hormuz standoff underscores the fragility of Trump's dealmaking claims and reveals Iran's leverage over global energy markets. Any escalation risks broader Middle East conflict and could force the U.S. to choose between military intervention and accepting higher energy costs—both politically and economically costly.

Trump signed an executive order Saturday accelerating research into psychedelic-based mental health treatments, specifically easing restrictions on ibogaine—a Schedule I drug—and other compounds for veteran care. The order bypasses traditional FDA timelines and signals a major policy shift on drug classification.

Psychedelic biotech and mental health companies (Compass Pathways, Atai Life Sciences, Mindmed) will see accelerated pathways to clinical trials and potential commercialization. The move also opens opportunities for contract research organizations and clinical trial networks. Expect biotech indices to respond positively on reduced regulatory risk.

This represents a fundamental recalibration of federal drug policy, moving away from decades of prohibition toward therapeutic use. The veteran focus provides political cover while potentially reshaping mental health treatment standards across the healthcare system if efficacy data emerges.

Solana futures open interest jumped 20% this week as SOL rallies alongside the broader crypto market, with traders positioning for a move toward $100. The surge in leveraged positioning reflects renewed institutional confidence in layer-1 blockchain ecosystems and Solana's technical infrastructure.

SOL's momentum is outpacing Bitcoin and Ethereum on a relative basis, attracting retail and quant capital. A break above $100 would signal a major technical breakout and likely trigger stop-loss cascades above that level, potentially accelerating the move. Derivative exchanges (FTX competitors, Bybit, Deribit) will see volume spikes.

The open interest surge indicates leverage is building in crypto markets, raising tail-risk concerns if sentiment reverses. Bitcoin mining difficulty is also rising, suggesting sustained network participation and confidence in long-term viability of proof-of-work systems.

Cerebras, a specialized AI chip designer, has filed for IPO after securing a strategic agreement with Amazon Web Services to deploy its processors in AWS data centers. The move capitalizes on surging demand for custom silicon alternatives to Nvidia's dominance in AI compute.

Cerebras' IPO will test investor appetite for AI chip diversification plays outside Nvidia (NVDA). AWS's endorsement signals enterprise validation and reduces execution risk; the deal also strengthens Amazon's (AMZN) ability to reduce Nvidia dependency. Semiconductor indices and AI infrastructure ETFs will track the offering closely.

The IPO reflects a broader shift toward vertical integration in cloud computing, with hyperscalers building proprietary silicon to lower costs and improve margins. Success here could embolden others (Google, Meta) to accelerate custom chip programs, fragmenting the AI accelerator market and pressuring Nvidia's pricing power.

Apple's App Store is experiencing a surge in new launches in 2026, with data from Appfigures showing AI tools fueling a mobile software renaissance. Simultaneously, traditional software ETFs posted their best week in 25 years as investors rotate away from pure AI infrastructure plays into application-layer software.

Apple (AAPL) benefits from increased App Store activity and commission revenue; software vendors (Salesforce, ServiceNow, Adobe) see renewed investor interest as compute rationing makes traditional software more cost-competitive. The iShares Software ETF (IGV) rally signals a potential peak in AI infrastructure hype and a pivot toward profitability-focused software.

The shift reflects market maturation: as AI compute becomes scarce and expensive, developers are optimizing applications for efficiency rather than raw processing power. This favors established software platforms over speculative AI infrastructure plays and could sustain a multi-quarter rotation into SaaS and application software.

Two high-profile traders have departed Jump Trading, including one from one of the firm's most profitable units. The exits follow years of competitive pressure from crypto platforms, AI-driven trading firms, and hedge funds aggressively recruiting quant talent with equity upside.

Jump Trading's departure of senior talent could impact its market-making operations and algorithmic trading strategies, particularly in crypto and derivatives. Competing firms (Citadel, Optiver, Jane Street) will likely absorb the departing talent, consolidating quant expertise. Volatility in crypto and equity derivatives may increase if Jump's liquidity provision diminishes.

The exodus reflects structural shifts in finance: traditional prop trading shops face retention challenges as founders and senior traders seek ownership stakes in newer, faster-growing platforms. Jump's Chicago dominance is being eroded by distributed, crypto-native, and AI-first trading operations.

Trump told the Daily Caller he is considering military action against Cuba, deliberately ambiguous on what "military action" entails. The comment follows months of hardline rhetoric on Latin America and suggests the administration is willing to escalate beyond sanctions and diplomatic pressure.

Oil markets will price in geopolitical risk if military action disrupts Caribbean shipping lanes or triggers broader regional instability. Emerging market currencies (particularly Mexico, Colombia) face depreciation pressure. Defense contractors (Raytheon, Lockheed Martin) may see modest upside on increased military spending expectations, while tourism and hospitality stocks with Caribbean exposure face headwinds.

The threat signals Trump's willingness to use military force unilaterally in the Western Hemisphere, raising concerns among U.S. allies about broader intervention doctrine. Any action would likely trigger international condemnation and complicate U.S. relations with Latin American governments already skeptical of Trump's return.

Multibillion-dollar dealership chains are consolidating the automotive retail sector, forcing independent dealers to either scale up or exit. The trend reflects decades-long industry consolidation accelerated by capital availability, digital retailing
