Investing in Commodities, but am I doing it wrong?

I invested in the CORN index because the forecast says there will be low-yield harvests next year, but for some reason it dropped in value once a news release confirmed this.

Shouldn’t that index be gaining in value with grain scarcity on the horizon, or did I get it reversed and that ETF drops in value when grains are scarce?

Thanks for any info.
