Volume
The total number of shares traded of a stock during a specific time period. (In this case, it is the latest trading day.) Unusually high volume days typically correspond with the announcement of company news, either positive or negative. In the absence of news, high volume can indicate institutional (or professional) buying and selling. See average volume.Back to Top
Williams %R
The Williams %R is used to put a stock’s latest closing price in context of its high and low closes, typically over a 10-day period. It is calculated by subtracting the highest close of the last 10 days from the most recent close, dividing it by the difference between the highest and lowest closes over that period and multiplying the result by 100. It is measured on a scale from -100 to zero, with zero being equal to the stock’s highest close over the last 10 days.Back to Top
Yield
The annual rate of return on a stock as paid in dividends. Yield can calculated by dividing the latest dividend rate by the latest closing price and multiplying by 100. The latest dividend rate is the total dividends paid in the past 12 months. As a stock's price rises, its yield will go down. As a stock's price decreases, its yield will go up.Back to Top
