SiriusXM Stock Jumps 49% This Week Due to Short Squeeze

Shares of SiriusXM soared 49.1% this week due to a “short squeeze” related to a trading strategy involving its parent company, Liberty Media. The stock rose 49.1% to $7.08, turning an 18.7% year-to-date loss into a 21.2% year-to-date gain.

On Thursday (July 22), SiriusXM shares increased 42.3% as 128 million shares were traded — about 6.7 times the average daily trading volume. The price fell 9.3% on Friday to close at $7.08 as trading volume reached 132.9 million shares.

As an article at Barron’s explained, SiriusXM, a heavily shorted stock, has benefitted from investors taking a long position in Liberty SiriusXM Group — a tracking that includes SiriusXM — and a short position in SiriusXM. (A short position is a bet that a stock price will decline. A long position is a bet the stock price will increase.) Those positions would benefit if Liberty SiriusXM Group, viewed as an inexpensive alternative to SiriusXM, was able to narrow the gap to SiriusXM. But SiriusXM shares have risen in recent months, turning the short into a losing bet.

Investors who short a stock must buy back borrowed shares to cover their short position. When a stock has a small public float — as SiriusXM does — demand for a limited number of available shares can drive up the price. This isn’t happening just with SiriusXM: Heavily shorted stocks helped the stock market rally in the first half of the year. “As expected, shorts are getting squeezed in these losing trades and we are seeing short covering in these stocks — helping drive stock prices even higher alongside the momentum long buying we are seeing in these stocks,” Ihor Dusaniwsky, managing director of S3 Partners, told Yahoo Finance last week.

SiriusXM was — by far — the best-performing music stock this week, as the Billboard Global Music Index rose 6.8% to 1,447.32, bringing the year-to-date gain to 23.9%. Eight of the index’s 21 stocks were in negative territory, one was unchanged and 12 stocks posted gains this week.

French music streamer Deezer boasted the week’s second-biggest improvement after gaining 10.3% to 2.58 euros ($2.87). On Thursday, the company announced it had renewed its partnership with telecom company Orange, which will continue to drive customer acquisition in its home market. Under the new partnership, Deezer and Orange will offer new customers six free months of Deezer Premium.

Live music companies also had a good week. Shares of Sphere Entertainment Co. gained another 8.9%. German concert promoter CTS Eventim improved 6.9%. And Live Nation shares rose 2.5% after Oppenheimer initiated coverage of the company with a $110 price target, suggesting the stock has a 14% upside from its $96.84 closing price on Friday.
