I'll check Oracle's weekly price history going back to 2001 to see if this is its worst week.

Only 22 weekly points since 2026-01-30 — not enough history. Let me load the full daily series and compute weekly returns going back to 2001.

No — it's not Oracle's worst week since 2001, though it is close.

Oracle (ORCL) worst weeks since 2001 (adjusted close, % change vs. prior week):

Week ending	Adj. close	Weekly return
Mar 2, 2001	$13.45	−23.27%
Aug 31, 2001	$9.73	−19.51%
Jun 26, 2026	$148.53	−19.40%
Sep 20, 2002	$6.37	−17.88%
May 3, 2002	$6.72	−16.78%
Aug 10, 2001	$12.08	−15.78%
Feb 9, 2001	$18.78	−15.10%
Apr 26, 2002	$8.07	−15.09%
Oct 10, 2008	$13.29	−14.37%
Mar 23, 2018	$39.65	−14.31%

So the week ending Jun 26, 2026 is the 3rd-worst week for ORCL since 2001, narrowly behind the dot-com bust weeks of March and August 2001. It is, however, the worst week since the 2008 financial crisis and the worst in roughly 18 years — a meaningfully bad week, just not quite a record.

Caveat: the week of Jun 26 is incomplete (Friday close as of Jun 26, 2026); if Oracle rallies into today's close it could move a couple of slots, but the worst-week-since-2001 framing does not hold either way.
