There's value in understanding market capitalization.
Market capitalization refers to the total value the market puts on a company.
It's calculated by multiplying the price of a stock by its total number of shares. So the concept of market capitalization is straightforward and pretty simple to grasp. The reason you want to know about it is that different sized companies perform differently. The details of how that happens, though, are not so clear. Other studies have argued that it is not the size that matters, but it is the attention and number of analysts that follow the stock.
