The peak highs in DE and AGCO during bullish markets tend to coincide with the highs in Corn Futures.
DE (Deer & Co) and AGCO are attractive growth and dividend paying stocks that do well in steady to strong economies even without strong Ag futures markets because of their exposure to the construction and infrastructure sectors . They tend to over-perform in years of Bullish Commodity Markets and Inflationary driven markets just as they have done since the 2020 lows. But just like Ag Futures, the stocks rise Fast and Fall hard. If the Funds decide to leave one (either equities or futures), the other seems to follow lower.
