On days when commodity shares take a bit of a pullback, its always interesting to see which stocks defy the market dip. Corporate bonds are notably strong and have given trend traders an option outside of the equity market. The iShares Canadian Corporate Bond E.T.F. (TSX:XCB) edged to another 52-week high today as the TSX dipped on retreating energy shares. XCB is 8-weeks into a Stock Trends Bullish trend. Although the ETF has underperformed the TSX over the past 13-weeks, investors should be exposed to corporate bonds.
