The war continues to escalate and the indexes continue to plummet for the fourth straight day as the usual concerns about rate hikes, inflation, and the spiraling cost of oil stubbornly dominate. Treasury yields are at years-long highs which is a pronounced negative for stocks which means the cost of borrowing to carry on business keeps getting higher. PPI today came in as expected and that combined with oil hitting $107/barrel vs $100 just yesterday has stoked fears of rate hikes this month for which the odds have catapulted to 70%. 

That vs yesterday’s 60 vs last Thursday’s 49%, going in the wrong direction fast. Because of the likelihood of higher borrowing costs, chip makers took a big dive between 2% and 5% among major players Nvidia, Micron, and Apple. The S&P has had its worst 4-day losing streak since June and is now down 3% from its August record but still up 11% for the year. Yesterday, volume was characterized as light even though it was only 0.2 shy of the average. Likewise, today’s volume is being called heavy even though at 15.1 billion, it is a mere 0.2 billion above the 14.9 average.
