Index funds are central to the story of Vanguard because index funds are passively managed, which is to say that they passively track an index, rather than actively researching, analyzing, buying, and selling securities. Since actively managed funds are more expensive to operate, they tend to lose in performance in the long run to the cheaper index funds; however, there are a minority of actively managed funds that have historically outperformed index funds.
Reasons to Invest in Vanguard Admiral Shares
Most actively managed funds lose to their benchmark index. For this reason, many investors think, why not just hold the same stocks of the index, keep management costs low, and win by simply matching the performance of the index? Many agree this is a solid investing strategy. To allow an investor to build on this type of strategy, Vanguard launched the Admiral Shares.
