Market Growth

If a market is shrinking it will mill make remaining competition very fierce due to less demand for products so less profits to be made and there is pressure to which business will liquidate next. There is little room for new ventures and little space for market growth.
If a market is growing there is a higher chance of success as there is more demand for the products, so more profits to be made. The market state encourages new ventures into products increasing their chance of success.
