TheStreet's Jim Cramer says he's keeping an eye on Monsanto Wednesday to see if the company can turn the tide when it reports Q2 results before the open. He says a lot of people are betting against Monsanto and he understands that because crop prices are down. But when Monsanto goes down a lot, be careful, he warns. It tends to be a caged tiger to go up, he says. He recommends to investors who want agriculture to go for Dow Chemical over Monsanto. With Dow, he explains, you've got the buyback, you have the spinoff of the chlorine business and you have a really nice dividend. He says the buyback is going to be up, the dividend is going to be up, they're offloading this chlorine commodity business to Olin and they'll have a gigantic crop protection business. So if you really want crops go to Dow, he says, as it is more diversified and less expensive. Dow Chemical is a core holding in Jim Cramer's Action Alerts PLUS charitable trust portfolio.
