2010 Q7D - Effective Beta

What exactly is effective beta? I don’t think i’ve come across it before. Once they calc the return (which makes sense) they just put the market movement / % return. Is this just a standard equation for it? What is it actually telling you?

Yiou must be using only Schweser

Effective beta is done in the first exdample in the forward and futures reading.

Basically you divide the return on your synthetic position by the actual market return

Many examples are in the forwards andf futures reading

Aaaahhh thanks.
