FAQ

How do you decide what counts as a change?

We compare each fund’s share count in every holding with the previous day, adjusting for money flowing into or out of the fund. A holding is marked only when the adjusted share count changes by more than 0.5%. Price moves do not count.

What is an “adjusted share count”?

It is the fund’s share count after accounting for money flowing into or out of the ETF. If the whole fund grows or shrinks, we adjust for that first, so we do not mistake normal investor flows for the fund actually changing a position.

Why track shares instead of portfolio weights?

Weights move every day as stock prices rise and fall, even when the fund does nothing. Adjusted share counts give a cleaner picture of when the fund has actually changed its position.

What does a change mean in an active fund versus an index fund?

In an active fund, a change reflects a manager’s decision. In an index fund, it reflects the index rules, often through a rebalance, reconstitution or other scheduled adjustment.

What do you leave out?

Cash, Treasury bills, money-market funds, currencies and futures are excluded from the Top 20. If a fund holds part of a company’s exposure through swaps, as DRAM does with Micron, we combine that exposure into the company’s row.

Why do some fund names glow, and some have an amber edge?

A fund’s name glows when the fund has changed a position. The glow stays for two trading days. An amber edge means that fund’s latest holdings file is older than the others’, so its numbers are from before the date shown under ETF MOVES.

Why do some funds show different dates?

Each morning, we check the funds’ latest published holdings. Changes reported for Monday’s market close typically appear here on Tuesday morning. If a fund’s file is behind, the date beside that fund tells you which trading day its holdings reflect.

What it could mean
