As you would read a car magazine before purchasing a new car or taking a look at a product review before deciding which kind of tablet or phone to get, investors are reading ratings before they decide in which kind of product they are investing their money.
你一般会先看看汽车杂志 再去买新车 或者是先浏览产品评价 再决定到底买哪种平板电脑或手机 投资者们则是先看评级 再决定 把钱投向哪种产品
