In acquiring, investing, reinvesting, exchanging, retaining, selling, and managing property for the benefit of a minor, a tutor shall exercise the judgment and care, under the circumstances then prevailing, which men of prudence, discretion, and intelligence exercise in the management of their own affairs, not in regard to speculation but in regard to the permanent disposition of their funds, considering the probable income as well as the probable safety of their capital. Within the limitations of the foregoing standard, a tutor is authorized to acquire and retain every kind of property and every kind of investment, specifically including but not by way of limitation, bonds, debentures, and other corporate obligations, and stocks, preferred or common, and securities of any open-end or closed-end management type investment company or investment trust registered under 15 U.S.C. §§80a-1 through 80a-52, as from time to time amended, which men of prudence, discretion, and intelligence acquire or retain for their own account.
