Nice chart as always Jako.

I have been playing around with my spreadsheet. Its the research scientist in me that I just have no control over.

The following chart shows how the ironers compared over the last 12 months. It just looks like a dollop of spaghetti thrown on a rectangular plate. But if you look a bit further there is in fact a lot of order to it.

If you compare each company against the index on a daily basis and then do regression analysis on it you get the following. Remember this is done on a dirty index where the crap companies are mixed in with the good ones and each has the same weighting.

The better the regression coefficient (in the box next to the companies letters) the more accurate the line fitting.
