Over $1 trillion was wiped out from the U.S. stock market yesterday, as reported by Financial Express (https://www.financialexpress.com/market/global-markets-why-did-us-market-crash-1-trillion-wiped-out-in-one-trading-session-4141147/). The technology‑heavy Nasdaq Composite slumped more than 2% in the risk‑off move.
Coverage framed the move as a tech/AI‑led rout tied to capex concerns and layoff headlines, with the S&P 500 turning red for 2026, according to Coinpaper (https://coinpaper.com/14570/us-stock-market-big-tech-erases-1-trillion-in-ai-selloff). The outlet also noted Bitcoin dipped below $67,000 alongside the equity drawdown.
The “over $1T wiped out” phrase refers to a change in market capitalization, not realized investor losses. Reported totals can vary by whether the calculation uses close‑to‑close values and which indices or constituents are included.
How ‘over $1 trillion wiped out’ is calculated
In practice, outlets total the aggregate market value of U.S.-listed equities at the prior close and compare it with the latest close, then state the difference. Some reports proxy this by summing losses across major indices at the close and rounding to the nearest large figure.
Because major indices are market‑cap weighted, losses often concentrate in mega‑cap technology and AI leaders, such as Nvidia (NVDA). Index composition means a relatively small group can drive outsized swings in headline dollar terms.
Context helps prevent misinterpretation of large dollar figures. “Headlines focused on ‘billions’ or ‘trillions’ in losses often lack context,” said Fisher Investments.
At the time of this writing, Apple Inc. closed at $261.73, down 5.00% on February 12, with a pre‑market indication near $261.98, based on data from Yahoo Finance (https://finance.yahoo.com/). This single‑name move illustrates how index‑level losses can be amplified by large constituents.
