A seemingly unstoppable flood of money has Vanguard Group Inc. on the brink of claiming a crown that State Street Corp. has held for decades.

But there's a small problem that might bother some investors. The average price-to-earnings ratio and price-to-book value ratio of Vanguard S&P 500 ETF are 27.7 and 4.9, respectively. For Vanguard S&P 500 Growth ETF, those figures are 34.6 and 9.4, respectively. The growth-focused version of the S&P 500 is looking really expensive right now.

An investigation by the S.E.C. and several states found that the company had failed to notify investors of changes in the terms of some funds, leading to higher capital gains taxes.

Investment management firm Vanguard offers a variety of exchange-traded funds (ETFs) that allow investors to target a specific theme or sector at a low cost. With just 0.04% expense ratios, meaning $0.

Vanguard exchange-traded funds (ETFs) are a fantastic choice for retired investors looking to play the long game with their portfolios. Undoubtedly, Vanguard is a name that passive investors can put their trust in.
