Overweight refers to an excessive amount of a specific asset or industry sector in a fund or investment portfolio compared to the benchmark index it tracks.1 It is also used to describe an analyst's opinion that a stock will outperform others in its sector or the market.1 In the context of investing, going overweight means allocating a higher percentage of a portfolio to a particular asset or sector than what is recommended by the benchmark index.1 This strategy is often employed to take advantage of promising opportunities or to protect against volatility.
