To check your performance versus your competitors, review the Market Share Pie chart report on the Industry Reports tree item.
To increase your market share you need to increase the rate of growth of your retails sales. Your options include increasing the retail price of your product(s) and/or trying to make your product(s) more attractive. It is important to remember that while increasing price will only increase your Retail Sales Revenue depending on how much demand falls for your product(s) as a result of the price increase.
