Still, Tim Ramey, of D.A Davidson, maintained a buy rating on the stock, with a price target of $44. Ramey said the audit committee report is clear that there was no intent to push costs through, adding the walnut costs were close to what should be accrued. Tamey said Diamond Foods can either continue operating its business or sell off some of its assets. He said he thinks it will continue to run the business, which he maintained was untouched by the scandal.
