eli5: index funds adding and removing stocks

307 viewsEconomicsOther

How does an index funds like Schwab® S&P 500 Index Fund (SWPPX) deal with S&P500 adding new companies and removing old companies that don’t preform well?

What happens to someone holding a SWPPX fund? Does the increase or decrease in the index make someone holding SWPPX fund pay more to match the index or receive money back?

If it’s an index fund, it mirrors the S&P 500. When the stock market index updates its list of companies (done quarterly), then index funds re-balance their portfolio holdings, too.
