Everpure (P) is printing an eye-catching gain of roughly 699% at about $67, but the move lines up with a market-data dislocation following the company’s NYSE symbol change from PSTG to P that became effective on April 17, 2026. When tickers change—especially to a single-letter symbol—some trading and charting systems temporarily mis-handle prior closes, split-adjusted histories, or reference prices, which can generate extreme percentage-change readings even if the underlying stock price is not actually up by anything close to that amount.

The most recent company-driven event is the ticker change itself: Everpure announced it would switch its NYSE trading symbol from PSTG to P, with trading under the new symbol expected to begin April 17, 2026, with no shareholder action required and the CUSIP unchanged. Options market operations also flagged the symbol change effective the same date, which typically triggers back-end mapping work across brokers, market makers, charting providers, and data vendors.

Everpure’s rebrand (from its prior identity as Pure Storage) has been paired with a broader positioning push around data management and AI-era workloads, and the company has highlighted strong fiscal Q4/full-year 2026 results in recent communications. That combination can lift attention and volumes around the symbol transition, but it does not, by itself, explain a true one-day ~700% increase in market value—reinforcing that today’s print is likely a percent-change artifact tied to reference-price handling around the new ticker.
