Korean e-commerce giant Coupang drops after massive data breach

Leading Korean retailer Coupang is down 9% after details of a breach of personal information from 33.7 million accounts came to light — one of the widest hacks on record for the country of some 52 million people.

“We sincerely apologize once again for causing our customers inconvenience,” CEO Park Dae-jun said in a statement. The company, dubbed the Amazon of South Korea, said on Saturday that the breach was only detected on November 18, but that it started as early as June 24, exposing customers’ names, email addresses, shipping addresses, phone numbers, and certain order details but not payment details or login credentials.

The Ministry of Science and ICT said in a statement on Sunday that it has formed a joint investigation team to analyze the cause of the incident after Coupang reported two breach cases on November 20 and 29. A Chinese national who previously worked at the company reportedly hacked the system, per Yonhap News, though that particular claim is unverified at this point.

AI “bottleneck” stocks are the big winners halfway through a tumultuous week

Memory stocks and chip machinery companies are bouncing Wednesday, following a strong Oracle earnings report that bolstered confidence in the durability of the AI data center build-out.

In fact, Sandisk is the top performer of the S&P 500 so far this week, rising more than 21% from Friday’s close, as of shortly after 2 p.m. ET. Memory chip maker Micron is second in line, up more than 13% in weekly gains, and hard disk drive maker Western Digital is also getting a lift.

Other big winners so far this week are some of the so-called semicap shares — makers of the ultraprecise machines that turn silicon into actual semiconductors — with Lam Research and KLA Corp both racking up gains of about 10% on the week. Applied Materials is up about 8% this week.

Thematically speaking, both memory stocks like Sandisk and Micron as well as semicap shares like KLA have been part of the “buy the bottleneck” trade, in which investors buy companies they believe sit at key pinch points in the AI supply chain and therefore have pretty tremendous pricing power. Through that lens, the stocks’ bounce might reflect some additional excitement about the durability of the data center boom after Oracle’s results, which included a larger-than-expected capex number as well as sales guidances that was higher than Wall Street was forecasting.

But the bounce also may be the less interesting market phenomenon of mean reversion rearing its head, as these stocks were also some of the most beaten down in the S&P 500 last week, when Sandisk lost 17% and Lam lost about 15%, for example. So, some snapback may merely be a market reflex.

Papa John’s spikes following report of a $47-per-share take-private offer from Qatari investment fund Irth Capital

A few weeks after announcing it would close 300 stores by the end of next year, Papa John’s is drawing fresh take-private interest from Irth Capital, an investment fund backed by a member of the Qatari royal family.

Papa John’s shares were up 19% on Wednesday afternoon, on pace for their best day since February 2025.

According to The Wall Street Journal, Irth is offering $47 per share for PZZA, valuing the company at about $1.5 billion. The fund currently holds a roughly 10% stake in Papa John’s, per the report.

Irth has tried to take Papa John’s private before, offering $60 per share in a joint bid with Apollo Global in June of last year. In October, Apollo Global again offered to take the company private at $64 per share. That offer was later withdrawn.

Broadly, the pizza category is being increasingly dominated by Domino’s, which opened 700 stores globally last year and has a market cap 9x greater than Irth’s latest reported offer for Papa John’s.
