Determine the current yield of the stock. This value will show how much you can get (what benefit) if you sell shares at the moment, the current market price. To do this, subtract from the value of the stockat which it is sold at the moment, the value of the stockat which it was purchased. For example: you bought a share for 100 rubles. Now it costs 120 rubles. In this case, it turns out: 120-100=20.
Divide the resulting value (20 roubles) worth of investments. That is, the amount of investment is the value of the shares, if you bought a few shares, you would need the price of the stock multiplied by its quantity. In this case, it turns out: 20 rubles to divide by 100 rubles (20:100=0,2).
Multiply the resulting value by 100%: 0,2*100%=20%. Thus, the yield of shares is 20%.
Calculate the yield of a stock for a specific period, e.g. a year. To do this, use the following formula: Yield = profit : amount of investments * 365 days : period * 100%.For example, the period is 200 days. Then the previous example turns out: 20:100*365:200*100%=36,50%.
Can the measurement period to make not in days, in months. In this case, simply substitute in the formula the required number of months, replacing the 365 days in the numerator, for example, at 17 months.
In turn, the income from shares is always formed by means of a difference in cost when buying and selling. In this case the result (value) as a percentage of the purchase price is called the yield of the stock. In addition, income from price difference from the purchase and sale of the securities, the investor may receive additional income from the payment of dividends.The yield of a stock can be positive, negative (in this case you will get only loss on securities) or zero.
