Owens Corning Stock Surges 4.88% on Institutional Backing Earnings Beat and Share Buyback as 330 Million Dollar Volume Ranks 313th in Market Activity

On August 22, 2025, Owens Corning (OC) saw a 4.88% rise in its stock price, with a trading volume of $330 million, ranking 313th in market activity. The surge followed a combination of institutional investment shifts, strong earnings performance, and a new share repurchase initiative.

Institutional confidence in OC was reinforced by a 30.7% increase in ownership by Candriam S.C.A., which now holds 220,712 shares valued at $31.52 million. This move underscored broader market validation of the company’s strategic positioning in the construction materials sector. Simultaneously, Owens Corning reported second-quarter earnings of $4.21 per share, surpassing estimates by $0.41, and achieved a 10% year-over-year revenue increase to $2.75 billion. The firm also announced a $12 million share repurchase program, signaling management’s belief in undervaluation and commitment to capital returns.

Technical indicators highlighted continued bullish momentum, with the 200-day moving average at $158.14 acting as a key support level. Options activity reflected heightened volatility expectations, particularly in the OC20250919C155 and OC20250919P150 contracts. These instruments offered varying leverage and risk profiles, catering to both aggressive long-term positions and hedging strategies. The RSI’s neutral reading and positive MACD divergence further suggested potential for sustained upward movement.

Historical backtesting of OC’s performance following significant intraday gains showed a 37.32% win rate over three days, 39.82% over ten days, and 36.58% over thirty days. This data reinforced the likelihood of continued positive returns in the short to medium term, aligning with the company’s recent operational and institutional developments.

A strategy based on purchasing the top 500 stocks by daily trading volume from 2022 to 2025 yielded a 1-day return of 0.98% and a cumulative return of 31.52% over 365 days. The approach demonstrated a Sharpe ratio of 0.79, indicating favorable risk-adjusted returns, though it faced a maximum drawdown of -29.16% during market downturns.
