(Bloomberg) -- Options traders are the most bearish on small U.S. companies since June 2012 as investors look for safer stocks after the worst selloff in more than a year.

Implied volatility on the iShares Russell 2000 ETF is 7.03 points above an exchange-traded fund tracking the Standard & Poor’s 500 Index, according to data compiled by Bloomberg on one-month contracts with an exercise price closest to the shares. The difference was 7.59 on Feb. 4, the widest gap in almost two years and 74% higher than the year average.
