Question about
Case
I want to receive updates regarding this question via email.

How do we get the value 30% market share for our customer?

Given Data:
The customer is the market leader in North America; in general around 80% of the market is accounted for 4 similarly sized competitors.

How do I derive 30% market share based on this piece of information?

Thanks!

Hi,
I think it is a rough estimation: since 4 competitors have the 80% of the market and the client is the leader, it will have more than 20% of market share, let's assume 30%.

Best,
Antonello

Hey, how is that possible? There are just 20 % of the market left left. I do not get it.

100% - 80% = 20% ....I don't understand either
