$1T Stock Wipeout
U.S. stocks lost about $1 trillion in market value today — a story amplified across X by Spectator Index (21K likes) and Watcher.Guru (13K likes) (x.com) (x.com). The social buzz underscores how traders are scrambling after a broad risk‑off move across equities (x.com).
An estimated $1 trillion in U.S. equity market capitalization was erased in a single session on Friday, March 13, with the S&P 500 down about 1.8% and the Nasdaq Composite roughly 2.4% at the close. (markets.financialcontent.com) The selloff was concentrated in software and data names: the S&P 500 software & services index fell across multiple sessions and had wiped roughly $830 billion in market value since late January, extending sector losses into March. (finance.yahoo.com) Traders pointed to a mix of catalysts that day — an escalation in the Iran conflict that sent Brent crude toward triple‑digit levels alongside softer U.S. macro prints (including GDP revisions and weaker job‑openings data) — which together pushed a broad risk‑off shift. (markets.financialcontent.com) Market structure amplified the move: the March quarterly options/futures expiries (“quadruple witching”) and an S&P quarterly rebalance left roughly $5.2–$5.7 trillion in derivatives notionals due around mid‑March, adding to intraday order‑flow volatility. (cannontrading.com) Mega‑cap technology names led headline losses — several Big Tech and software gauges have lost more than $1 trillion combined across recent selloffs, with Amazon, Microsoft and Nvidia among the largest single‑day market‑cap losers during the stretch. (bloomberg.com (cnbc.com)) Institutional desks said automated selling accelerated declines mid‑session while some large buyers re‑appeared late, creating a pattern of heavy early selling followed by selective “bottom‑fishing” as key technical supports were breached.
