A 1 700% jump turns retail trader favourite Sivers into short bet

A small Swedish semiconductor firm that’s soared about 1,700% this year has become one of the country’s most-shorted stocks.

Traders have piled into tiny companies like Sivers Semiconductors AB as part of the frenzy for companies that are building artificial intelligence infrastructure like optical components that can transmit data. The firm, which has a market value of 23.5 billion kronor ($2.5 billion) after its surge, makes optical components that can transmit data.

But now, skepticism is growing around the stock’s rapid rise, says Calle Soderberg, an investment economist at Nordnet AB. About 17% of Sivers shares that are available for trading are out on loan, according to data from S&P Global Market Intelligence as of May 26. That’s up from around 1.6% at the start of March.

“There is a lot of speculation here, the risk in the stock is seen as high,” Soderberg said. “There are likely many investors who are ‘dancing close to the exit’ and are prepared to take quick profits in this extremely volatile stock if sentiment turns.”

The recent rally has set Sivers up for inclusion in equity benchmarks, with Nasdaq saying it will be added to the OMX Stockholm Benchmark Index on June 1 and MSCI. tapping it for a small-cap gauge. Still, the stock has little analyst coverage among established brokers, according to data compiled by Bloomberg.

A representative for Sivers didn’t respond to emails from Bloomberg News seeking comment. Investors will be looking for evidence of whether the rally can continue when the company reports its latest earnings on Friday.
