Can someone give me a simple definition of 'market share'?

Question

every one i find is complicated

Answer 1

How much of a market a firm occupies. For example, Microsoft has a very large market share in the computer industry.

Answer 2

The market is the total of a segment of the economy. That represents 100%. The amount of that segment owned or  serviced by an entity is the market share. Bank of America services about 10% of the banking business.That 10% is their share of the market.

Answer 3

It is not complicated, it is dead simple. Say you make a left handed widget and the market for these is 100 a year total. You sell 25 left handed widgets a year so you have a 25% market share.

Answer 4

If you have 30 % shareholding in a company, you own 30% of that company. Similarly, if your business has 30% business exposure in the Banking industry, your market share in that Industry is 30%.

Answer 5

As Senior Vehicle Arrangement Officer for our supermarket, I am well placed to answer your question (Which I agree does sound complicated, although in fact it is not)

Market Share presupposes that there is a definable market measurement.

It also suggests that there are several players.

The number of players in the definable market have a powerful or less powerful impact on the defined or definable market. Their power or lack of it results in a definition of the relative position,

This position is known as market share.It is always in a state of flux.

What's with the widgets? Widgets are not the issue here. Ignore the next answer.
