Statistical composite that measures changes in the economy or in financial markets, often expressed in percentage changes from a base year or from the previous month. Indexes measure the ups and downs of stock, bond, and some commodities markets, in terms of market prices and weighting of companies in the index.

A statistical measure of the value of a certain portfolio of securities. The portfolio may be for a certain class of security, a certain industry, or may include the most important securities in a given market, among other options. The value of an index increases when the aggregate value of the underlying securities increases, and decreases when the aggregate value decreases. An index may track stocks, bonds, mutual funds, and any other security or investment vehicle, including other indices. An index's value may be weighted; for example, securities with higher prices or greater market capitalization may affect the index's value more than others. One of the most prominent examples of an index is the Dow Jones Industrial Average, which is weighted for price and tracks 30 stocks important in American markets.

The relative value of a variable in comparison with itself on a different date. Many security price indicators such as the Standard & Poor's series and the New York Stock Exchange series are constructed as indexes. Also called stock index. See also base period.


To adjust a variable by a selected measure of relative value. For example, it has been proposed that an investor's basis on a security be indexed for changes in consumer prices so that only real increases in value will be taxed. Also called tax indexing. See also subindex.

An index reports changes up or down, usually expressed as points and as a percentage, in a specific financial market, in a number of related markets, or in an economy as a whole.

Each index -- and there are a large number of them -- measures the market or economy it tracks from a specific starting point. That point might be as recent as the previous day or many years in the past.

For those reasons, indexes are often used as performance benchmarks against which to measure the return of investments that resemble those tracked by the index.

A market index may be calculated arithmetically or geometrically. That's one reason two indexes tracking similar markets may report different results. Further, some indexes are weighted and others are not.

Weighting means giving more significance to some elements in the index than to others. For example, a market capitalization weighted index is more influenced by price changes in the stock of its largest companies than by price changes in the stock of its smaller companies.

(1) A statistical indicator that measures changes in the economy in general or in particular areas.An example is the cost-of-living index.(2) A reference point against which measurements are taken for purposes of making future adjustments.An adjustable-rate mortgage might begin with an interest rate of 6 percent and provide that it will increase or decrease in a like percentage as the increase or decrease between today's quoted price for 10-year U.S.Treasury bonds and the price on the loan's annual anniversary date.We would say that 10-year T-bonds are the index.

Some leading loan indices include

• Wall Street Journal prime
• Federal discount rate
• Fed funds rate
• 11th District Cost of Funds
• 10-year Treasuries
• One-year LIBOR

The study also reports no significant difference in the traditional red cell indices (MCV, MCH, MCHC and RCDW) of iron-deplete and iron-replete patients, and therefore the routine use of these indices alone in screening for ID in children with CKD may be misleading.
The prevalence of reduced red cell indices was similar in a study of cardiothoracic and orthopaedic surgical patients published by Grey et al (26).
Age-dependent reference ranges for red cell indices are even less well defined than for Hb level.
In patients with IDA, we observed a significant positive correlation between serum sodium levels with all red cell indices except MCV and also between serum bicarbonate levels with Hb, RBC count, HCT, and MCV.
Morphologically it was microcytic hypochromic anemia as the red cell indices of anemic subjects were lower than normal levels.
Haemoglobin, serum ferritin and red cell indices mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) were used for diagnosis of iron deficiency anemia.
If the CRP is elevated, IDA can be diagnosed in patients with coexistent ACD in the presence of a CHr <28 pg and hypochromic red cell indices.
Transition from fetal to adult erythropoiesis and the physiologic anemia of infancy are accompanied by gradual changes in hemoglobin concentration, red cell count, red cell indices (MCV, MCH), and red cell distribution width (Fig.
Blood samples (2 cc) anticoagulated in ethylenediami-netetraacetic acid (EDTA) were run in an automated hematology analyzer (Abacus) for counts and red cell indices.
Routine investigations including complete blood count (CBC), erythrocyte sedimentation rate (ESR), red cell indices, platelet count and reticulocyte count were carried out on all subjects.
The division was done using a method based on difference in red cell indices such as mean corpuscular volume (MCV) published by Hermiston and Mentzer [12].
These values are within range of the red cell indices of the captive Thailand Hill Mynah, which are 38.36 [+ or -] 3.57pg, 30.06 [+ or -] 1.53%, and 126.04 [+ or -] 11.69 fL for MCH, MCHC, and MCV, respectively.
