Vanguard 500 Index Fund (Admiral) (VFIAX)

VFIAX sits below its recent price averages for the first time in several weeks.

What is going on right now?

This fund, which holds a slice of the 500 largest U.S. companies, has drifted down slightly. Its price has been losing small ground day by day, and it now sits a little over 1% below where it averaged over the past month.

How is the business itself doing?

It collects a tiny fee, just four cents for every hundred dollars, to mirror the performance of those 500 companies. About four out of every ten dollars inside it sit in technology companies, with Nvidia, Apple, and Microsoft alone making up roughly a fifth of the whole fund.

What stands out?

The ten largest names account for about 39% of the fund. So even though it holds 500 companies, its day-to-day moves lean heavily on a handful of giant tech names.

What comes next?

Reports about big spending on artificial intelligence by those top tech companies are circulating, and how that spending shows up in their next earnings could shift a meaningful chunk of this fund's value.
