Larry Fink is sounding the alarm. The chairman and CEO of $4.4 trillion asset manager BlackRock is worried about leveraged ETFs (exchange-traded funds).

Investors tend to lose money in boring, but effective, ways. Motif Investing (“turn any idea into a motif”) promises to disrupt this predictable pattern by helping people lose their money in new and exciting ways.
