Fastest V-Shaped Market Recovery on Record
An a16z Charts of the Week essay analyzes the rapid S&P 500 rebound following a geopolitical sell-off, concluding it was the fastest V-shaped recovery on record — the index fell ~10% during the Iran conflict and regained losses in 11 trading sessions, closing at an all-time high of 7,165.08. The piece surveys drivers behind elevated equity valuations: large cash pools (money market funds at roughly $8 trillion), an enlarged Fed balance sheet (peaked near $9T, at $6.7T today) and historically wide profit margins. It contrasts investor warnings from Warren Buffett and Paul Tudor Jones with structural differences today (AI-driven semiconductors led by Nvidia, cloud backlogs, and growing earnings). The note also covers platform trends (YouTube AI tools adoption, Meta DAU decline, falling global social-media time) and spillovers into software credit markets (software-backed loans trading at discounts).

S&P 500’s Rapid Rise Last Seen Before 1987 Crash
The S&P 500 climbed more than 16% across April and May 2026 — a pace Deutsche Bank Research says has occurred only four other times since World War II. Three prior instances were rapid recoveries after major economic shocks (April‑May 2020, March‑April 2009, January‑February 1975); the last comparable non‑recession run-up occurred in the months before the 1987 crash. Deutsche Bank macro strategist Henry Allen warned the speed of the rally bucked recent precedents for a non‑recessionary economy. The rally is driven largely by enthusiasm for AI and large‑cap tech gains (Micron joined the $1 trillion club; Nvidia CEO Jensen Huang said Marvell could follow), while analysts cite risks including potential Fed hikes, tight credit spreads, elevated consumer savings behavior and geopolitical oil‑supply concerns (Strait of Hormuz).
Why Markets Are Hitting Record Highs
Despite recent geopolitical shocks — collapsed Iran peace talks, a U.S. blockade of the Strait of Hormuz and IMF warnings about oil-driven recession risk — U.S. equity benchmarks (S&P 500 and Nasdaq) reached fresh all-time highs. The article explains this resilience by citing historical market behavior during crises, five consecutive quarters of double-digit S&P 500 earnings growth, concentration of consumer spending among the top 10% of earners, and a rotation back into large-cap tech after a March drawdown. It also covers rising anti‑AI sentiment and incidents targeting AI leaders and data centers, and reports Amazon’s announced $11.57 billion acquisition of satellite operator Globalstar to obtain spectrum for its Amazon Leo satellite plans and private wireless network ambitions.
Retail Investors Drive Record Trading Activity
The a16z Charts newsletter highlights a sustained surge in retail market participation and several related macro trends. Retail trading — both cash equities and options — is at or above prior record levels, with Citadel Securities reporting May on pace to be the busiest month for retail cash equity volume. Retail investors are taking on more leverage (margin balances at major brokers exceed $250B) and concentrating in areas like semiconductors. Separately, hyperscalers have dramatically increased bond issuance tied to AI capex (~$150B printed in 2026) and AI-related debt now accounts for a large share of 2026 corporate issuance. The piece also notes regulatory/procurement shifts (FedRAMP 20x approvals accelerated) and the growing importance of retail media: Walmart’s US ad revenue is accelerating and grocers are monetizing first-party shopper data more aggressively.
