Process High It earns a High Process Pillar rating.The strategy tracks the S&P 500, which selects 500 of the largest US companies that pass its liquidity and profitability screens. The profitability screen requires that the sum of a company’s GAAP earnings over the past four quarters be positive as well as the most recent quarter. The screen imparts a slight quality tilt to the portfolio but doesn’t distinguish it from similar benchmarks since large-cap stocks tend to be profitable. There have been instances where the profitability screen prevented otherwise qualified companies from index inclusion. Most notably, Tesla was added to the index only in December 2020, despite passing the liquidity and market-cap thresholds in January 2013. Once the index committee selects stocks, it weights them by market cap.Market-cap weighting harnesses the market’s collective wisdom on a stock’s relative value and helps reduce turnover and associated trading costs. The index committee further curbs turnover by implementing changes as it sees fit rather than adhering to a strict reconstitution schedule.The strategy approximates the contours of the large-cap market. Its sector composition is in line with its average peer in the US large-blend Morningstar Category, and no sector deviates by more than 4 percentage points as of year-end 2024. The fund’s value-growth and market-cap orientation both mirror the US category average, too.Market-cap weighting consistently guides the index into the largest and most established names. As of year-end 2024, 94% of the strategy’s assets were companies with wide or narrow Morningstar Economic Moat Ratings, showcasing the portfolio’s durability.This strategy is well-diversified. The average large-blend fund’s top 10 holdings represent approximately 50% of their portfolios as of year-end 2024; this strategy’s top 10 holdings represented 37% of the portfolio. While that’s lower than the US category average, it’s an increase from previous years. For example, in 2015, the top 10 holdings hovered around only 17% of the total holdings. Stocks such as Microsoft and Apple were some of the largest holdings then. They still ranked in the top 10 as of December 2024, but both their weightings have more than doubled since 2015. by Brendan McCann , Vanguard Institutional Index Fund Institutional Shares (VINIX) - Find objective, share price, performance, expense ratio, holding, and risk details., MUTF: VINIX - Vanguard Institutional Index I VINIX stock price, growth, performance, sustainability and more to help you make the best investments..
