NEW YORK (TheStreet) -- Shares of Monsanto (MON) were edging up in early-morning trading on Monday as Bernstein raised its rating on the stock to "market perform" from "underperform," the Fly reports.

The firm also upped its price target to $105 from $90 on shares of the St. Louis-based agricultural company.

The higher rating comes after Bayer (BAYRY) agreed to buy the company in a $66 billion deal.

Bernstein cautioned that "it's too early to tell" whether regulators will approve the acquisition, the Fly added. The firm noted the risk is "skewed to the downside in the near-term."

Bernstein recommends that investors avoid Monsanto stock for six to nine months. 

Separately, TheStreet Ratings Team has a "Hold" rating with a score of C+ on Monsanto stock.

The primary factors that have impacted the rating are mixed. The company's strengths can be seen in multiple areas, such as its good cash flow from operations, expanding profit margins and solid stock price performance.

But the team also finds weaknesses including feeble growth in the company's earnings per share, deteriorating net income and generally higher debt management risk.

Recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
