Short sellers are having a magnificent week. The chip rout has handed them an estimated $32 billion in gross paper gains over seven days, according to S3 Partners data compiled by Bloomberg, as the Philadelphia Semiconductor Index (the SOX) sank more than 12%.

The SOX extended its losses into an eighth straight session on Friday, putting it on track to match its longest selloff since 2006, Bloomberg reported. Chip stocks have erased roughly $1 trillion in market value, and suppliers of equipment for AI computing facilities have been hit especially hard. Quartz reports that 20 of the index's 30 components fell more than 10%. Coherent lost nearly 30% despite 34% quarterly revenue growth to $2.05 billion, as AI financing fears weighed on chip stocks.

The pain is spreading. The S&P 500 is headed for a weekly loss of 1.7%, its worst since June, and the Nasdaq 100 is projected to drop 5% by the end of the week. Bloomberg points to rising borrowing costs, elevated valuations and heavy spending on AI infrastructure.

For context: between the end of March and its June peak, the index more than doubled, adding approximately $6.5 trillion in market capitalization to its constituents.

My take, darling: up $6.5 trillion, down $1 trillion, and somebody still racked up an estimated $32 billion in gross paper gains on the way down. That is not a market. That is theater with a ticker, and the seats are historic.
