OC Call Buyers Step In After 17% Drop

Why this matters: Owens Corning has shed 17% over the past month. Yet options traders are now buying calls at the most aggressive pace in months. That divergence between price action and positioning is the sharpest signal in today's data.

Calls Dominate the Options Market

The put-call ratio hit 0.215 on September 10. That's 2.28 standard deviations below the 20-day mean of 0.504. It sits near the 52-week low of 0.206.

The shift is stark. Through most of August, the PCR held steadily above 0.55. It collapsed after September 4. Call volume has surged even as the stock continued to slide — a classic divergence setup that options watchers track closely.

Wells Fargo Cuts, But Consensus Holds

This morning, Wells Fargo analyst Sam Reid lowered his price target on OC from $172 to $150. He maintained an Overweight rating. The stock trades at $127.49 — so even the trimmed target implies roughly 18% upside from current levels.

The broader analyst picture remains constructive. The consensus is Buy, with a mean target of $176.53. That's 38% above the current price. DA Davidson initiated coverage at Buy with a $190 target on August 25. Evercore ISI holds a $194 target.

Analysts see a stock trading at a steep discount. The PE stands at 11.2x. The EV/EBITDA is 7.3x.

Short Interest Ticks Up — But the Borrow Market Is Loose

Short interest rose 13.3% on September 10, reaching 2.8% of free float. That's a noticeable single-day jump. But context matters: availability sits at 1,384%. There are roughly 14 shares available to borrow for every one already lent out. The borrow market is wide open.

Cost to borrow has also dropped sharply — down 52.8% over the past week to just 0.23%. That's a near-record low. Shorts face no friction entering or exiting positions here.

The short score stands at 34.2, up slightly from 33.3 a week ago — a modest tick, not a trend.

Peers Falling Too

OC is not alone. Its closest peers are all under pressure this week. BLDR is down 6.5% over five days. FBIN is down 7.3%. HAYW is off 5.5%. The entire building products group is being re-rated lower.
