JPMorgan analyst Jeffrey Zekauskas said commentary from the CEOs of DuPont (DD) and Syngenta (SYT) and press reports from Europe suggest that their deals with Dow Chemical (DOW) and ChemChina, respectively, are likely to be approved. Approvals from Europe for those deals may "trigger a meaningful closing of the arbitrage spread" in Monsanto (MON) shares versus Bayer's (BAYRY) offer price, Zekauskas tells investors. He recommends buying Monsanto shares at current levels for this reason, adding that he believes the shares would only fall about 2.5%, or down to $112, in the event of the Bayer deal falling through. Zekauskas keeps an Overweight rating and $128 price target on Monsanto shares, which closed yesterday at just below $115 per share.
