iShares iBoxx $ Invmt Grade Corp Bd ETF (LQD) - Inexpensive Corporate Bond ETF
iShares iBoxx Investment Grade Corporate Bond ETF ( *LQD*) seems to offer 1% better return than Vanguard Total Corporate Bond ETF (VTC). Also it's bonds are better rated (A as compared to BBB) and it's expense ratio of 0.140% is comparable. Vanguard Interm-Term Corp Bd ETF (VCIT) has lower quality (BBB instead of A) and is less diversified. Accordingly, it should have produced better performance (than LQD) due to these added risks. But, it hasn't.
