Help with Forecasting Sales

[Parker]

Hello there. PLEASE HELP!!

I sell a product in a market of 4 other products. I want
to forecast my market share (and when we can be market
leader) based on historical data. I have the historical
data for all products and each product's current market
share. Can you help me figure this out?

I understand how to forecast my growth in market share,
but I have no idea how to include the pther products so
that it is accurate, and I will know when I can pass
them.

Thanks for any help you can give!

Parker,

If you applied the same calculation logic that you use for your market share
to the other products your analysis would be internally consistent.
