Software-event claims: the contrarian result needs its register
A dated correction preserves first-party company schedules and a product announcement while withdrawing unsupported price, basket, return and trading claims.
What changed in this article
Editorial correction · 9 September 2026. The original article was published on 23 February 2026 and described a February 20 cybersecurity shock, a nine-episode IGV rapid-flip study, median forward returns, drawdowns and entry thresholds. It did not preserve the complete CRWD and IGV price rows, episode dates, event identifiers, inclusion rule output or execution record. Those price, sample, return, probability and trading-rule claims are withdrawn. The original URL and publication date remain unchanged.
An official product announcement and a company earnings calendar can establish dates. They do not establish a sector return or a causal reversal in software valuations.
What the dated records establish
| Source date and record | Dated fact | Boundary |
|---|---|---|
| 3 February 2026 · Workday first-party announcement | Workday announced that its FY26 fourth-quarter and full-year results would be released after market close on Tuesday, 24 February 2026. | This establishes a scheduled company event. It does not validate a CRWD close-to-close move or an IGV event study. |
| 4 February 2026 · Salesforce first-party announcement | Salesforce announced a release after market close on Wednesday, 25 February 2026. | This is calendar evidence, not a peer-basket return or an influencer signal. |
| 2 February 2026 · Snowflake first-party announcement | Snowflake announced FY26 results for Wednesday, 25 February 2026 after the U.S. market close. | The announcement does not supply the article's 50-name lineup or event-study calculations. |
| 20 February 2026 · Anthropic product announcement | Anthropic announced Claude Code Security as a limited research preview. | The release does not establish a CRWD price observation, an IGV proxy response or causality. |
The later Workday, Salesforce and Snowflake results releases are after the preserved article's information boundary. They remain separate chronology and are not used to rewrite the article's February 23 setup.
What is withdrawn
The −7.95% CRWD move, nine-episode IGV universe, +1.58% and −0.79% forward medians, win rate, drawdown figures, episode dates, “contrarian edge,” value-trap classification and entry/invalidation thresholds are not verified findings. No replacement price return, sector forecast or buy/avoid instruction is published.
The neutral question—whether a defined software shock followed by a narrative change has different outcomes from a delayed entry—remains possible only after the event and price registers are frozen.
Minimum register for a future software-event study
Record the exact announcement and market timestamps; issuer and ETF identifiers; exchange, currency and adjusted-price convention; target and candidate windows; prior-return and shock rules; non-overlap and deduplication; entry/exit times; benchmark; fees/slippage; and every event-level calculation.
