Most Shorted Week of Jul 22nd Preview:

Looking ahead to the week of July 22nd, several of the most shorted stocks reporting earnings show positioning influenced by recent corporate actions. In the U.S., Charter Communications remains heavily shorted following its merger with Cox, which includes $6B in convertible preferred notes, potentially driving hedge-related short interest. QuantumScape has also issued convertible preferred shares, and its stock has more than doubled month-to-date with no significant change in short interest, suggesting structural or locked-in positioning and potential squeeze risk—current QuantumScape S3 Squeeze Risk Score: 100. Enphase is the most shorted stock in the S&P 500 by float, with shares short up 4.6% month-to-date ahead of the firm’s Q2 report. In Europe, Italgas completed a rights offering to fund its acquisition of 2i Rete Gas, and Edenred is midway through a buyback—both likely supporting high but non-directional short interest. Several names show rising short interest into earnings: Screen Holdings (+15.2%), Galderma (+14%), Medpace (+6.0%), and Charter (+4.1%). Meanwhile, short interest declined in Canon (–10.1%), Italgas (–10%), and Edenred (–8%), signaling potential de-risking ahead of results. These shifts help identify where positioning risk is building—and where shorts may be stepping back.

Most Shorted Week of Jul 14th Recap:

Several of the most shorted stocks that reported the week of July 14th saw outsized price moves following earnings, many of which were preceded by notable shifts in short interest. In APAC, Toho Co. saw short interest rise +16.2% ahead of earnings and the stock jumped +10.9% afterward—suggesting traders were caught short when the company delivered a surprise boost from non-core investment income, including gains on securities, which helped offset a ~55% drop in cinema operating profit. POSCO Future M gained +19.6% post-earnings, with a more modest +1.0% build in short interest ahead of the report. In EMEA, Ocado jumped +18.5% after a –2.6% drop in short interest pre-release, likely reflecting early short covering. On the downside, Electrolux fell −15.9% after missing earnings expectations, with short interest roughly flat into the print—indicating the market was already positioned for weakness. These examples underscore how changes in short interest ahead of earnings can flag positioning risk and help explain sharp post-report price moves—highlighting the value of tracking real-time short interest data.
