    Finding weighting factor to estimate proper market data

    Hello,
    I have problems with some basic math. Please help us.
    How to calculate an appropriate market factor combing GDP market share, industry market share and a growth rate of the specific market.

    For example
    GDP = 25 %
    Industry market share = 40%
    Growth rate = 6 %

    Just multiplying the numbers does not solve the problem since the number end up quiet small. One idea might be to calculate a weighting factor based on industry market share and growth rate that can be multiplied with GDP percentage

    What do you want to do with the number you end up with?

    I want to calculate an index for a market and compare markets to each other.
    Equation might look like this

    m= x*GDP

    X-should be weighted figure of industry market share and growth rate

    The way you ask the question it seems that such a factor is essentially arbitary and so there is no objective criteria for choosing between proposed factors.
