IBM Just Had Its Worst Trading Day Since 1987.
A one-day 25% collapse anchored a week that also delivered a $53 billion PayPal buyout, a Hormuz war scare, and a halted Korean stock exchange — and the sector board still can't settle on a direction.
Dear reader: if you had to sum up this week for someone who'd been off the grid since Friday, the honest answer is that the market spent five sessions arguing with itself and wound up almost exactly where it started — out of breath, and no wiser for the trip. The sector-momentum board opened the week at four green sectors out of eleven and closed it at four green sectors out of eleven, a net-zero scoreline hiding a week that, session by session, looked nothing like a net-zero week. In between, IBM lost roughly a quarter of its own value in a single Tuesday session, its worst day since the market-wide crash of October 1987 — not a fair comparison in scale, since 1987 took the whole Dow down with it and this was one company's AI-infrastructure-spending warning, but it's the honest yardstick a number that ugly forces you to reach for. The S&P slipped roughly half a percent across the four sessions we have on the books, the Nasdaq fell a sharper 1.5%, and the Dow finished nearly flat — three headline indexes that, taken alone, would have you believe nothing happened this week. Plenty happened.
The week opened on a weekend war scare. The U.S. and Iran traded strikes over the Strait of Hormuz, oil spiked as much as 5% into Monday's open, and the "buy oil, sell chips" trade ran hard through Monday and Tuesday: Energy (XLE) jumped 3.01% Monday while Marvell fell 7.75%, Arm Holdings fell 7.55%, Oracle fell 6.47%, Micron fell 4.32%, and AMD fell 4.21% by Tuesday's close. Technology, which had helped carry three of the board's four green sectors into the weekend, flipped straight to red. Gold and silver, which are supposed to catch a bid when a shooting war breaks out, instead fell — gold 1.51%, silver 1.49% — while the dollar firmed, a small tell that the market wasn't yet convinced this was the real thing.
Then Tuesday delivered the week's actual headline. June's Producer Price Index cooled for the first time in roughly ten months, which should have been the day's story. Instead IBM reported an AI-infrastructure-spending warning that took the stock down 25.21% to $217.07 — a crash steep enough that this Radar has to reach back to 1987 to find a fair single-session comparison — and it kept bleeding into Wednesday, down another 2.69% to $247.02, before a modest 3.72% bounce Thursday. Financials told their own dispersion story the same week: Goldman Sachs posted a Q2 blowout and jumped 8.99% Tuesday, then got sold anyway later in the week, down 4.91% Thursday; Citigroup missed and fell 5.29% Tuesday before recovering 1.28% Wednesday. None of it moved together. That is the definition of a market taking profits and cutting losses stock by stock, not sector by sector.
The other real story confirmed itself Wednesday: PayPal's board agreed to a $53 billion take-private bid from Stripe and Advent International at $60.50 a share, a roughly 28% premium first reported Tuesday and confirmed Wednesday when the stock jumped 17.2% to $55.52. It kept climbing Thursday, up another 2.18% to $56.73 — still trading below the reported offer, which is the market's way of saying the deal isn't fully priced as done yet. It is the week's best reminder that even with a chip complex in retreat and one Dow component down a quarter of its value in a single session, private capital is still willing to write nine-figure checks on the belief that payments infrastructure is worth more than Wall Street currently prices it.
Thursday brought the week's final twist: Samsung and SK Hynix crashed hard enough overnight that Korea's exchange briefly halted trading in both, and the pressure carried straight into the U.S. session — Marvell fell another 8.71%, and Micron's monthlong slide passed 25%. Yet the same day, UnitedHealth and GE Aerospace both raised full-year guidance, Abbott Laboratories posted a genuine beat-and-raise that sent the stock up 10.71%, and the board's momentum count climbed back to 4 green, 4 yellow, 3 red — identical to where it opened the week. Then, after Thursday's close, Netflix reported a record $12.56 billion quarter undercut by weak Q3 guidance, and shares were indicated down roughly 9% heading into Friday's premarket — a session's worth of tape this recap doesn't yet have in hand, and next week's first order of business.
This Week's Five Biggest Movers
Monday, July 13 through Thursday, July 16 — the last closing tape available this run.
IBM's worst session since 1987. Big Blue fell 25.21% Tuesday to $217.07 on an AI-infrastructure-spending warning, then kept sliding 2.69% Wednesday before a modest 3.72% bounce Thursday — the single largest individual-stock move of the week by a wide margin.
PayPal's confirmed $53 billion take-private bid. Stripe and Advent International's $60.50-a-share offer, first reported Tuesday, was confirmed Wednesday as PYPL jumped 17.2% to $55.52 and kept climbing Thursday (+2.18% to $56.73) — still below the reported offer price.
The Hormuz war scare's "buy oil, sell chips" trade. A weekend U.S.-Iran flare-up sent crude spiking as much as 5% into Monday's open; Energy (XLE) rose 3.01% Monday while Marvell (−7.75%), Arm (−7.55%), Oracle (−6.47%), Micron (−4.32%) and AMD (−4.21%) absorbed the other side of the trade by Tuesday's close.
Asia's chip-market meltdown and the Korea Exchange halt. Samsung and SK Hynix crashed hard enough overnight that Korea's exchange briefly halted trading in both names; the pressure carried into Thursday's U.S. session as Marvell fell another 8.71% and Micron's monthlong slide passed 25%.
The sector board's four-session round trip. Momentum swung from 3 GREEN (last Friday's close) to 4 GREEN (Monday) to a 2 GREEN low (Tuesday, the same day IBM crashed) to 3 GREEN (Wednesday) and back to 4 GREEN by Thursday — ending the week at the identical headline tally it started with, even though barely any individual sector held the same color the whole way through.

Final Word — A Week That Ended Where It Started, and Nowhere Near It
IBM lost more of its own value in a single Tuesday session than most companies lose in a bad year, and it earned the 1987 comparison honestly — not because the two crashes share a cause, they don't, but because a number that ugly forces you to reach for the worst yardstick you know. The week's other headline, the $53 billion PayPal buyout, is the reminder that belongs next to it: even in a market jumpy enough to halt a Korean exchange and crash a Dow component 25% in a day, private capital is still willing to write nine-figure checks on the belief that some businesses are worth more than the public tape says. And the board's round trip — 3 green to 4 to a 2-green low to 3 and back to 4 — is this week's real lesson for anyone trading rather than gambling: an unchanged headline count tells you almost nothing about how violently the picture moved to get there. Monday brings Netflix's guidance miss to trade for real instead of on premarket rumor, plus whatever Samsung and SK Hynix do once Korea's exchange reopens for business. The close is a headline. The trend is the truth. This week, the trend spent four sessions arguing with itself before landing right back where it began.
