Which Is the Better Vanguard Short-Term Bond ETF, Corporate Bond-Focused VCSH or BSV's Treasury Emphasis?

Vanguard offers two compelling short-term bond ETFs with identical 0.03% expense ratios. VCSH focuses on corporate bonds with a higher 4.50% yield but greater volatility, while BSV provides broader diversification with 70% Treasury exposure and a 4.00% yield. The choice depends on risk tolerance: VCSH suits yield-seeking investors, while BSV appeals to conservative investors prioritizing capital preservation.
