Price-Earnings Ratio

The price of a security per share at a given time divided by its annual earnings per share. Often, the earnings used are trailing 12 month earnings, but some analysts use other forms. The P/E ratio is a way to help determine a security's stock valuation, that is, the fair value of a stock in a perfect market. It is also a measure of expected, but not realized, growth. Companies expected to announce higher earnings usually have a higher P/E ratio, while companies expected to announce lower earnings usually have a lower P/E ratio. See also: PEG

1. In stock-index futures, the number multiplied by the futures price to determine the value of the contract. For example, the $500 multiple of the Standard & Poor's Midcap Index is multiplied by the futures price to determine the value of one contract. Thus, a futures price of $230 would yield a contract value of $115,000 ($500 × $230).

A stock's multiple is its price-to-earnings ratio (P/E). It's figured by dividing the market price of the stock by the company's earnings.

The earnings could be the actual earnings for the past four quarters, called a trailing P/E. Or they might be the actual figures for the past two quarters plus an analyst's projection for the next two, called a forward P/E.

Investors use the multiple as a way to assess whether the price they are paying for the stock is justified by its earnings potential. The higher the multiple they are willing to accept, the higher their expectations for the stock.

However, some investors reject stocks with higher multiples, since it may be impossible for the stock to meet the market's expectations.

There are two methods that can extend our treatment to cases of multiple alleles and loci.
The Tag-It genotyping platform represents a valuable tool in the rapid, accurate, and cost-effective detection of multiple alleles associated with the risk of thrombophilia.
To estimate the frequency of a putative null allele, we can extend the approach used for the ABO blood group system in humans (e.g., Li 1970; Hedrick 1985) to multiple alleles and assume that there are five codominant alleles and one null allele.
Genotyping by melting analysis is advantageous because multiple alleles can be analyzed with one probe (5), whereas other methods require one probe for each allele.
(1978) showed that the allele frequency change at a locus in one population is related to the allele frequencies at the locus in the other population and, consequently, for multiple alleles the accumulation of different alleles can also occur in the absence of overdominance.
Single sequence repeat markers are advantageous because of single locus inheritance and the ability to detect multiple alleles. Consequently, SSR markers were used in this study to determine genetic relatedness among soybean lines.
Each allele has a characteristic [T.sub.m], and multiple alleles can be identified by a single probe.
