Wolfspeed’s share price was relatively stable in early September after its Chapter 11 filing in June. On Sept 9, shares jumped ~48% to $1.82 when the court confirmed the reorganization plan. After trading near that level for weeks, Sep 29 brought unprecedented volatility. Speculation and heavy buying drove WOLF sharply higher: by late morning, shares were up over 1,100%. Benzinga reported WOLF trading around $14.97 by midday, and market data show an intraday high near $19.80. Several volatility halts occurred as the NYSE managed the extreme moves Economictimes. MarketBeat notes that by the close, WOLF settled around $21.62, reflecting how dramatically sentiment swung. In short, Wolfspeed moved from a sub‑$2 penny stock to double‑digit territory on Sep 29, driven entirely by the restructuring news.
