It closed at $17.92 on Oct. 19, down 4.78%, after touching a new 52-week low of $17.86 on roughly 12.52 million shares—about 1.5 times its 8.49 million average.

• Moving-average structure: Price is below the 20-day, 50-day and 200-day averages. The $18.50 to $19.40 area is the first resistance zone.

2: Volume & Momentum

• Volume: Oct. 19 volume was approximately 12.52 million shares versus the 8.49 million average, roughly 1.5 times average.
• Volume-price relationship: The 4.78% decline on 1.5-times-average volume confirms significant selling pressure and a genuine breakdown.
• Momentum: Barchart's technical opinion is 88% Sell with a strongest short-term outlook for continuation. Relative strength is below 30%, and the market is in oversold territory.

• A hold above $17.86 followed by a higher low would be the first stabilization sign.

• A sustained close above $19.40 to $20 would provide stronger evidence of trend repair.
• A close below $17.86 would invalidate the immediate stabilization thesis.
• A break below $17.28 would increase downside risk toward $16.70 to $17.00.
• Track Q3 results on Nov. 3, phosphate and potash prices, agricultural demand, cost pressures, margin recovery, free-cash-flow generation and the dividend.
