Does the fund bet against companies?
The two equity funds do. Each holds small short positions against companies, ones that profit if the company falls behind. A manager who studies the whole market learns as much about weak businesses as strong ones, and in an ordinary fund most of that knowledge goes in a drawer. Here both sides of that research reach the portfolio. The growth fund uses the short side to extend its ranking, and the dividend fund uses it to blunt part of a decline.1
Those positions are deliberately small and spread across many names rather than concentrated in a few, each kept to a size the fund can afford to be wrong about.
The income fund is different. It shorts bonds rather than shares. It holds corporate bonds and sells government bonds short to keep its sensitivity to interest rates low, and it can also short a borrower’s bonds where the credit work turns against it.
