Corteva completed the spin-off of its seed business as Vylor on October 1 (a pro rata in-kind dividend to holders of record on September 24, per Corteva's 8-K), so Corteva (CTVA) now trades as the crop-protection company and its price history is being rebuilt; it is excluded from every comparison below. For the other nine names the week was a rebound from a clean red sweep: seven of nine closed green, Deere is still the only name in an uptrend (16.9% above its 200-day, RSI 56), and fertilizer remains the weak corner: Mosaic (-14% vs its 200-day), FMC (-36.1%, RSI 27.1) and Nutrien (just under the line at -0.4%).

Numbers are the settled October 2 close for all 10 names (Friday), one week after the September 25 scan. CTVA's summary carries a distribution stamp and no history windows because of the October 1 spin-off; this scan states no price change, RSI or trailing figure for it. Nine names are compared. Comparison baseline is the September 25 scan.

Corteva first. On October 1 the company distributed its seed business to shareholders as Vylor Inc. (VYLR), per its filed 8-K and the October 1 event file. The raw CTVA price series steps down because of that distribution; the desk's data layer marks the row as a distribution and withholds its history windows, so no return or RSI is quoted here. Whatever Corteva does from here is a new series for the crop-protection company; the old chart cannot be compared to it. Vylor itself is not in this list.

Deere is the one clean name: 16.9% above its 200-day, 48.76% trailing year, alpha 33.75, and -4.74% from its 52-week high. It gained 2.96% on Friday, but its news pull is from September 4, so the day is cause unknown. It is the book's only uptrend label.

Fertilizer is where the book is still broken or breaking. FMC sits at RSI 27.1, 36.1% under its 200-day, with a -73.15% trailing year, alpha -88.15 and a 30-day change of -36.68%; this is the worst name on every window and damage rather than discount, with no cause on file (news not pulled for this move, last pull September 3; stock-events and the October 1-2 captures checked). Mosaic is 14% under its line with alpha -54.39 and moved -2.23% on Friday against a mostly green group. CF Industries (2.2% above its 200-day, 30-day change -17.42%) and Nutrien (-0.4%) are the two where a trend is still being tested: both carry positive alpha (13.01 and 2.25) and an intact thesis rating.

The grain traders and the funds are in the middle: ADM is 8.1% above its 200-day with alpha 21.1; Bunge is 8.1% under its line with alpha 13.54; DBA (3.9% above its line, -4.44% from its high) is the commodity fund and shows the group is not collapsing, only the fertilizer and agribusiness-equity half.

• Corteva: spin-off of Vylor completed October 1; CTVA is out of all comparisons because its history windows are deliberately null. On September 25 it was sitting exactly on its 200-day.
• Breadth: seven of nine comparable names green today versus an all-red session on September 25.
• Below the 200-day: five of nine (NTR, MOS, BG, FMC, MOO) versus three (MOS, BG, FMC) on September 25; Nutrien and MOO slipped under the line while CF's cushion shrank to 2.2%.
• Negative alpha: four (MOS, FMC, DBA, MOO).
• Deere's RSI is 56, near where it was on September 25 (58.5), after a 2.96% Friday.

Do not read Corteva's chart as a crash. The distribution of Vylor shares is a corporate action; the data layer withholds the comparison windows on purpose. The right tape read for CTVA is 'spin-off completed, new series begins', and any entry thinking waits for a few weeks of clean post-spin bars.

For the other nine, the long layer splits the book in two. Deere, ADM and CF still have positive alpha and a trailing year above 25%; the fertilizer and fund names (Mosaic, FMC, DBA, MOO) do not. A low RSI in Mosaic or FMC is damage; a low RSI in CF or Nutrien (RSI 35.6, 36.5) is a pullback in a trend that still carries a positive alpha.

Source limits: price and RSI against moving averages only; no crop-price, fertilizer-price or weather data. Several news pulls in this book are weeks old, which is stated where it matters.
