Invesco MSCI USA ETF is a passively managed ETF with a focus on U.S. bellwethers. PBUS has a greater depth of exposure than iShares Core S&P 500 ETF, as well as stronger growth characteristics, plus it beat it a few times in the past. Its returns since inception are still weaker than IVV's. Another concern is its deep maximum drawdown. Besides, its lower earnings yield and slightly weaker quality detract from its appeal.
Invesco MSCI USA ETF offers a diversified portfolio of nearly 600 U.S. large-cap and mid-cap stocks with a low expense ratio of 0.04%. PBUS has slightly outperformed the S&P 500 index since inception, with comparable downside risk and higher growth exposure. PBUS is more diversified than the S&P 500, covering about 85% of the U.S. market-cap with 590 stocks.
