Any percentage changes in a stock price will result in an equal percentage change in a company's value. This is the reason why investors are so concerned with stock prices and any changes that may occur since a $0.10 drop in a $5 stock can result in a $100,000 loss for shareholders with one million shares.
The primary meaning of libra was balance or scales (as in the astrological sign), but it also stood for the ancient Roman unit of measure libra pondo, meaning a pound by weight.. We got the word pound in English from the pondo part of the libra pondo but our abbreviation comes from the libra.
In the imperial system, stone and pound are well known units of measurement of weight (ounce is another such unit). Let us start with ounce as it is the smallest of the three to understand stone and pound. One ounce is one sixteenth of a pound, which means 16 oz= 1 lb (pound) and 1 oz=28.35g. One pound (to differentiate it from money, pound (weight is written as lb) is one fourteenth part of a stone, which means that one stone = 14 pounds. Whereas ounce, which is smaller, is used to refer to measurement of spices, pound is used in the measurement of fruits and vegetables.
