DGT provides equal-weighted exposure to 150 of the world's most prominent companies as determined by the Dow Jones Averages Committee. The equal-weighting reduces the concentration in the fund's top holdings that might otherwise stem from the fund's small basket. Still, with only 150 names in the portfolio, DGT misses many names at the lower end of the large-cap spectrum, as well as some more obvious exclusions. Despite this, DGT stacks up reasonably well. The fund does not necessarily replicate the index but uses a sampling strategy instead. The index rebalances once a year (in September) unlike many equal-weighted strategies, which rebalance quarterly.
