Four different lenses
VTI is designed for broad U.S. market exposure. VIG emphasizes companies with records of increasing dividends. VUG emphasizes large-cap growth companies. VGT concentrates on U.S. information-technology companies.

VUG is a growth-style strategy, while VGT is a sector strategy. A technology company may appear in both, but a growth company does not have to be a technology company.
