Total return by period#

Annual

Methodology#

Returns are total returns (dividends reinvested), computed from NGG's split- and dividend-adjusted closes. The bar chart switches between annual and monthly periods. Annualized return is the compound annual growth rate over the full period. The current year is year-to-date. Past performance does not predict future returns; not investment advice.
