Cleveland-Cliffs Inc. shares fell 7.88% to $11.22 on Friday as reports emerged that its Stelco unit would idle some steel operations in Canada due to U.S. tariffs. The selloff was driven by concerns over the company’s operational flexibility and profitability in the face of trade policy pressures. The move outpaced broader declines in the steel sector, with CLF’s drop being the most severe among its peers.

What Happened

Cleveland-Cliffs announced that its Stelco subsidiary would reduce output at a Canadian steel plant, citing the impact of U.S. tariffs. This decision, reported by multiple outlets including Reuters and Bloomberg, raised concerns about the company’s ability to maintain production levels and margins in the current regulatory environment. The news triggered a sharp sell-off in CLF shares, which fell nearly 9% at one point during the session. The stock’s decline was steeper than that of other steel producers like Nucor and Steel Dynamics, highlighting the market’s negative reaction to the idling of key operations.

What The Data Shows

Over the last eight trading sessions, CLF has fallen 12.1% from $12.76 to $11.22. The stock has traded between $7.73 and $16.70 over the past 52 weeks, and is currently near its 52-week low. Unusual options activity has also been observed, with put options collecting $4.5 million in premium, compared to $0 in call premium. The largest single options print was $2.2 million. On September 28, the stock printed one fresh 52-week high and 17 fresh 52-week lows, underscoring its volatile performance.

What To Watch

Cleveland-Cliffs is not scheduled to report earnings in the near term, but investors will closely monitor coverage breadth and any follow-up developments on the Stelco idling decision. Analyst activity, including the recent Buy ratings from GLJ Research, may also influence the stock’s direction.
