Vanguard vs. iShares by BlackRock
Since we use both Vanguard and iShares by BlackRock Exchange Traded Funds (ETFs) extensively, one of my pleasures over the last few years has been seeing each company try to outdo the other by lowering costs. As they continue to lower costs, they gather more and more investments. As referenced in a recent Bloomberg article, together they account for 64% of the ETF market as Vanguard is getting close to the size of BlackRock.
