Short sellers are on the move. ORTEX data dated August 20 shows several notable jumps in short interest over the past week.
RDDT saw the biggest increase among large-caps. Short interest as a % of free float jumped to 17.6% from 13.5% — a 4.1 percentage-point rise in just seven days. Reddit's stock has attracted growing bearish attention, possibly tied to monetisation concerns.
WB — Weibo — is flashing an extreme warning signal. Utilisation hit 100% and availability collapsed to just 3.6% of short interest. That means shorts are nearly out of borrowable shares. Citigroup downgraded the stock to Neutral today and slashed its price target 16% to $7.80. Bears are squeezed for room.
WOLF remains deeply shorted. Wolfspeed's SI sits at 83.4% of free float — with zero shares available to borrow. The semiconductor firm is down 62% over three months. Days to cover stands at 7.1, making a short squeeze structurally difficult.
CHTR (Charter Communications) also saw a 2.9pp rise in short interest this week, now at . Cable operators face mounting pressure from cord-cutting.
On the macro front, chip stock volatility continues. NVDA and peers swung sharply this week, though short interest on mega-caps remains minimal — shorts are not the driver there.
