CRSP: Bridging theory and practice

May 1, 2017


In the latest issue of ETF Perspectives, Vanguard insights for financial advisors™, David Barclay of the Center for Research in Security Prices explains how CRSP constructs indexes for U.S. equities and keeps them reliable and investable.

Also in the spring issue:

  • ETF liquidity. Bid-ask spreads are typically tighter for ETFs than for individual stocks. Learn why ETFs can have more liquidity, even if volume for an individual ETF is relatively low.
  • Index differences. Find out why similar benchmarks from different providers can perform differently.
  • REITs. This sub-asset class can be volatile, but it can also provide diversification benefits. Learn how to best consider REITs when constructing a client's portfolio.

  • Vanguard ETF Shares are not redeemable with the issuing Fund other than in very large aggregations worth millions of dollars. Instead, investors must buy and sell Vanguard ETF Shares in the secondary market and hold those shares in a brokerage account. In doing so, the investor may incur brokerage commissions and may pay more than net asset value when buying and receive less than net asset value when selling.
  • All investing is subject to risk, including possible loss of principal.
