This is misleading, I think. Depends on the fund. Some seek to match the benchmark through a certain exposure to derivatives and synthetic things. Others hold the stocks in proportion.

The vanguard funds I'm invested in don't have much synthetics - they own the stocks

As far as I'm aware they also have flexibility in when they sell or buy stocks, so they don't need to buy them the second you move money in etc.
