Higher Food Prices Bane of Farmers, Boon to Agriculture ETFs

Reticon,
By double top, I assume you mean 43 for DBA. Chartists are like weathermen. One sees double top, another sees support at 34, still another sees 35. Today it broke the 200-day moving average, which is supposedly bearish.
On the fundamental side, the cost of production, energy, fertilizer and seeds, have gone up compared to last year. The demand only increases. Unless you predict a bumper crop, the bull won't die.
