The Warsaw Stock Exchange Index (WIG) is an all-share index that measures the overall performance of the Warsaw Stock Exchange (WSE). It includes all companies listed on the main market except those under delisting procedures.

Historical Context

The WIG index was launched on April 16, 1991, coinciding with the re-opening of the Warsaw Stock Exchange following Poland’s transition from a centrally planned economy to a market-oriented economy. It played a crucial role in the re-establishment of the financial markets in Poland and has since become a barometer of the Polish economy.

Types and Categories

The WIG Index can be divided into several sub-indices based on market sectors, including:

WIG20: Represents the 20 largest companies listed on the WSE.
mWIG40: Covers medium-sized companies.
sWIG80: Includes small-sized companies.

These sub-indices help investors to analyze different segments of the market.

Key Events

1991: Introduction of the WIG index.
2004: Poland’s accession to the European Union led to increased market activity.
2008: Global financial crisis impacted the WIG index but also showcased the resilience of the Polish economy.
2018: WIG index reached record highs, reflecting growth in the Polish economy.

Detailed Explanations and Mathematical Formulas

The WIG index is a total return index, meaning it reflects both the price performance of constituent stocks and dividend payouts. The formula to calculate the WIG index is:

WIG_t = \frac{\sum_{i=1}^{N} (P_{i,t} \times Q_{i,t})}{\sum_{i=1}^{N} (P_{i,0} \times Q_{i,0})} \times WIG_0

where:

\(P_{i,t}\): Price of stock \(i\) at time \(t\)
\(Q_{i,t}\): Quantity of stock \(i\) at time \(t\)
\(P_{i,0}\): Price of stock \(i\) at base time (initial calculation)
\(Q_{i,0}\): Quantity of stock \(i\) at base time
\(WIG_0\): Initial WIG index value
