Big buyer in brutal selloff

Tuesday’s brutal selloff in the aftermath of August’s hotter-than-expected inflation numbers looked like an opportunity to Cathie Wood’s Ark Investment Management. The firm bought 27 stocks across its eight exchange-traded funds that day, according to data compiled by Bloomberg. This was her largest buy.

The potential US rail strike this week threatens to push inflation even higher. About 125,000 workers could walk off the job if a deal isn’t reached by Friday’s deadline, with talks between rail companies and unions not showing signs of progress. The stoppage would be the largest of its kind since 1992, snarling a wide range of goods—from food to metal and auto parts. The White House is considering an emergency decree to keep key items flowing, and Labor Secretary Marty Walsh hosted talks with the parties on Wednesday.

Shortly before Russia invaded Ukraine in February, Vladimir Putin and Xi Jinping declared a “no limits” friendship. Yet even though Putin’s forces are now suffering humiliating losses, he shouldn’t expect much help at the Thursday meeting with his Chinese counterpart.

Stunned by lightning Ukrainian gains on the battlefield, Putin faces narrowing options as he seeks to turn the tide in the war he started. Some of his deputies are rattling the nuclear saber again.

Ethermine, the largest Ethereum mining services provider by computing power, will shut down its servers for miners after the blockchain completes its historic technical upgrade.

Georgian billionaire Bidzina Ivanishvili’s $800 million lawsuit against a trust firm owned by Credit Suisse Group is set to become a test case for the global industry handling billions of dollars in assets for wealthy families. A win for Ivanishvili may force a major rethink of how and when trust operators flag unusual transactions or other shady practices.
