Adobe shares surged on Monday as investors rotated into software names following the broader market rebound from three consecutive weeks of losses. The rally reflects easing concerns about the Iran conflict's impact on tech valuations, with the stock benefiting from renewed appetite for mega-cap software exposure after a brutal selloff that saw software shorts hit 17-year highs.
Stocks rose on Monday, while oil prices pulled back as Wall Street tried to recover from another losing week, with investors monitoring the latest developments of the Iran war. The Nikkei 225 Index rose 0.5% to around 54,000 while the broader Topix Index gained 1.5% to 3,665 on Tuesday, snapping a three-day decline and tracking a rebound on Wall Street overnight as easing oil prices helped lift investor sentiment, with the move coming as several tankers safely navigated the Strait of Hormuz. The conflict remains the dominant macro driver, with markets oscillating between supply shock fears and de-escalation hopes.
Software shorts are at the highest level since the 2008 financial crisis, with median short interest across software companies spiking to over 5%, marking the highest level in about 17 years. Monday's rebound saw software names like Adobe (+2.14%) lead the charge as investors rotated back into beaten-down mega-cap tech. The extreme short positioning suggests a potential squeeze if the market continues higher, but fundamental concerns about AI disruption remain.
The average mortgage interest rate on a 30-year mortgage is 6.12% as of March 17, 2026, according to Zillow. The Middle East conflict still weighs on the bond market and home loan rates are now the highest in three months. Despite the recent oil pullback, mortgage rates remain elevated due to lingering inflation concerns and the Fed's patient stance on rate cuts, pressuring housing affordability as buyers enter spring season.
Australian bank analysts are piling on to forecast an RBA rate hike next week, with Westpac lifting RBA peak rate forecast to 4.35%, seeing RBA hiking rates in March and May as inflation risks rise. The Reserve Bank of Australia's decision to tighten reflects the global transmission of energy price shocks, with oil-importing economies facing stagflation pressures that force central banks to prioritize inflation control over growth support.
Treasury Secretary Scott Bessent told CNBC that the United States is currently allowing Iranian oil tankers to pass through the Strait of Hormuz. WTI crude futures settled at $93.5 per barrel, down 5.28%, while Brent crude futures in London settled at $100.21 per barrel, down 2.84%. The move signals a potential de-escalation in the three-week-old Iran conflict and removes the primary driver of stagflation fears that had dominated markets since late February. The S&P 500 rose 1.01% to close the session at 6,699.38, while the Nasdaq Composite climbed 1.22% to end at 22,374.18, and the Dow Jones Industrial Average climbed 387.94 points, or 0.83%, to 46,946.41.
💡 Stagflation (stagnation + inflation) — an economic environment combining slow growth with rising prices, which typically forces central banks into a policy bind: cutting rates risks inflation, while raising rates risks recession. The Iran conflict threatened this scenario by spiking oil prices, which would push headline inflation higher while slowing growth. Easing oil prices removes that tail risk.
Nvidia (NVDA) CEO Jensen Huang combines his company's cutting-edge AI breakthroughs with his signature humor and leather jacket style in his keynote address at the GTC 2026 event. The sales figure is an update to last year's forecast, when Huang said chip sales would total $500 billion through 2026. The announcement signals confidence in sustained AI infrastructure demand despite recent market volatility, with Nvidia positioning itself as the critical infrastructure layer for the AI buildout.
Elon Musk has acknowledged that xAI 'was not built right' and is undergoing a complete rebuild from the ground up, with multiple co-founders—including Tony Wu, Igor Babuschkin, Kyle Kosic, and Christian Szegedy—having departed in recent weeks. With SpaceX's upcoming IPO tied to xAI's trajectory, this represents a pivotal moment for AI startups racing to challenge incumbents. The restructuring highlights the technical debt and scaling challenges facing even well-funded AI ventures.
Meta and AMD formalize a 60 billion dollar AI chip partnership tied to a 6 gigawatt GPU rollout and expanded multivendor compute strategy. The deal signals Meta's commitment to reducing Nvidia dependency and building custom silicon for its AI infrastructure, mirroring similar moves by Google and Amazon. This diversification reduces concentration risk in the AI supply chain and could pressure Nvidia's margins long-term.
Circle (CRCL) stock jumped as much as 10% on Monday amid deepening stablecoin adoption and expectations that the Federal Reserve will push back interest rate cuts, with the issuer's USDC (USDC-USD) in circulation surpassing $79 billion in March, up 5% year to date and more than 25% since the passage of the GENIUS Act last year. Higher-for-longer interest rates and a growing supply of the stablecoin boost the company's reserve income, as investors have also pared back expectations that the Fed will cut rates anytime soon as surging oil prices raise concerns about higher inflation.
Prediction market leaders Kalshi and Polymarket are reportedly exploring fundraising rounds that could value each company at roughly $20 billion, even as lawmakers and courts intensify pressure on the sector. On Tuesday, U.S. Sen. Adam Schiff introduced the DEATH BETS Act, a bill that would bar prediction platforms from listing contracts tied to war, terrorism, assassination, and deaths. The regulatory battle reflects growing concerns about insider trading and the ethical boundaries of prediction markets.

Scientists have discovered that cells can sense far beyond the surfaces they touch, with individual cancer cells able to probe about 10 microns ahead by tugging on surrounding collagen fibers, while clusters of normal epithelial cells can combine forces to sense even farther. The discovery, published March 16, 2026, reveals a previously unknown mechanism by which cancer cells may navigate tissue and metastasize, opening new avenues for understanding tumor progression and potential therapeutic targets. This finding challenges the conventional view that cells only respond to immediate contact signals.
💡 Metastasize — the process by which cancer cells spread from a primary tumor to distant sites in the body. Understanding how cancer cells sense and navigate their environment is critical for developing treatments that block this process.
