DWS Investments is seeking to launch the DWS Variable NAV Money Fund, which does not strive to maintain a stable $1 share price. The U.S. Securities and Exchange Commission has considered the idea to bolster the resiliency of money-market funds. DWS Investments' announcement is premature because the SEC has not made a final decision, said Peter Crane, president of Crane Data, a firm that tracks money funds. Meanwhile, many industry experts, including Crane, said the concept is a bad one. "It's fraught with peril and confusing to the marketplace," Crane said.
