Indices

To say it simpler, an index can be defined as a portfolio of stocks listed on a stock market. Most major economies or developed countries have at least one stock exchange or financial index. The Dow Jones, S&P 500, Dax 30 are examples of indices. If most stocks value go up, then generally speaking the value of an index will also rise.

Big companies impact the index more
Since the performance of an index is based on the capitalization weight of a stock, it means that companies which have higher share price, influence the performance of the index more than the smaller companies.

WHAT DRIVES INDICES PRICE CHANGES?

There are many factors which can impact the price movements of indexes, even though not clearly determined. Let’s consider some of them:

At the most crucial reason, supply and demand in the market decide on stocks prices.

Price multiplies the number of shares (market capitalization) is the value of a company. Comparing just the prices of two different companies does not give you a right insight. The trader needs to know what part of the market a certain company occupies.

Theoretically, earnings are what affect the valuation that investors have about the company. There are of course other indicators that are used by investors to have a future idea over the movements of stocks price. And exactly, it is investors mood, sentiment, attitudes, responses towards certain stocks and their expectations that affect stock prices.

There are many theoretical explanations over how the stock’s price move, their fluctuations and the periods of time they happen the most. But, up to now there is no a general theory which can explain everything over the behavior of all the stocks under one index.
