GARDINER — Maine’s top securities official is releasing her agency’s annual listing of the top traps for investors.

Securities Administrator Judith Shaw says the “top traps” list includes risky investments that can often turn sour for investors looking to rebuild their damaged nest eggs.

She says investments that deserve special scrutiny include gold and precious metals; so-called “green” technologies; gas and oil schemes; exchange-traded funds, or ETFs; and foreign-exchange trading schemes.

Shaw says investors should also be wary of affinity fraud scams; undisclosed conflicts of interest; “off-the-book” deals; and unsolicited online pitches.
