Stock Rating System
1.Three Grades of Stock Rating
IRI's stock rating system consists of the following three grades:
A=Buy: The stock price is considered more than 20% below its fair value.
B=Neutral: The stock price is considered within 20% plus or minus its fair value.
C=Sell: The stock price is considered more than 20% above its fair value.
In addition, IRI provides the following ratings:
Comprehensive rating on risk of change in financial conditions and business results, risk relating to management executives and other corporate risks. Risk rating is classified into three grades - LR (low risk), MR (medium risk) and HR (high risk) - depending on the degree of risk involved.
2.Valuation to Obtain a Fair Value
The fair value of a stock is calculated on the basis of its expected earnings growth rate, with allowance for risk premiums unique to individual stocks. In the case of small- and mid-cap growth stocks which IRI specializes in, risk premiums are generally considered to be higher than the market average. And individual stocks have unique unsystematic risks resulting in another premium. IRI combines both risk premiums (namely, small- and mid-cap stock risk premiums and unsystematic risk premiums) as "Risk Premiums Unique to Individual Stocks."
