Both market advisors and researchers have often suggested multiyear rolloverhedging as a way to increase producer returns. This study determines whetherrollover hedging can increase expected returns for producers. For rolloverhedging to increase expected returns, futures prices must follow amean-reverting process. To test for the existence of mean reversion inagricultural commodity prices, this study uses a longer set of price dataand a wider range of test procedures than past research. With the use ofboth the return predictability test from long-horizon regression and thevariance ratio test, we find that mean reversion does not exist in futuresprices for corn, wheat, soybean, soybean oil, and soybean meal. The findingsare consistent with the weak form of market efficiency. Simulated tradingresults for 3-year rollover hedges provide additional evidence that theexpected returns to the rollover hedging strategies are not statisticallydifferent from the expected returns to routine annual hedges and cash saleat harvest.
