A large investor bought into my fund - what does it mean

An investor who owns 5% or more of a fund must tell the regulator, and must say whether it may push for changes. Here is what that notice means for you.

Your broker or the news may call the notice a "13-D filing" when the investor may push for changes, and a "13-G filing" when it says it will not.

Two kinds of notice

One notice says the investor is passive: banks, brokers and index funds file this way, and so do some specialised investors while they wait. The other says the investor may push for changes - a buy-back, new managers, or closing the fund down - and must be updated whenever the stake changes by about 1% or the intentions change. Our fund pages tell the two apart in the first box.

Why they do it

A closed-end fund's shares often trade below the value of what the fund owns. An investor who buys at that price and then persuades the fund to buy back shares or close down gets the full value. Some investors specialise in exactly this and have done it at dozens of funds; their pages here list every fund they have been in, and what happened.

What it can mean for a holder

Often nothing for months. When it leads somewhere, it leads to a vote or a buy-back offer - both come to you in the post with a date, and both are described in the guides linked below. The share price sometimes moves closer to the value of the holdings while an investor is pushing; it can move back if the investor sells.

What we do

We read every such notice on the day it is filed and e-mail holders who asked to be told. The fund's page shows who owns how much, since when, and whether they are pushing; the investor's page shows the pattern across funds.
