  1. How about a chart comparing the stock market to farm prices? I'm wondering if there is correlation in the rise of the stock market and the fall of farm values.

    A more direct correlation would likely be falling/low interest rates to farmland prices. Or increased ag commodity prices to FL prices. I have seen comparisons made of FL prices to the stock market, but I think they just used averages over decades.
    Thanks for commenting.
