'''BUX''' is a [[Blue chip (stock market)|blue chip]] [[stock market index]] consisting up to 25 (currently 16) major [[Hungary|Hungarian]] companies trading on the [[Budapest Stock Exchange]]. Prices are taken from the electronic [[Xetra (trading system)|Xetra]] trading system. According to the operator [[Budapest Stock Exchange]], the BUX measures the performance of the Equities Prime Market's 12 to 25 largest Hungarian companies in terms of order book volume and market capitalization.<ref>{{Cite web |url=http://bse.hu/topmenu/marketsandproducts/indices/indicies/bux.html |title=Bse - Bux |access-date=2015-10-14 |archive-url=https://web.archive.org/web/20160124033209/http://bse.hu/topmenu/marketsandproducts/indices/indicies/bux.html |archive-date=2016-01-24 |url-status=dead }}</ref> It is the equivalent of the [[Dow Jones Industrial Average]] and [[DAX]], the index shows the average price changing of the shares with the biggest market value and turnover in the equity section. Hereby this is the most important index number of the exchange trends.

BSE was one of the first in the world who started to use [[Capitalization-weighted index|free-float capitalisation weightings]] instead of the traditional [[market capitalisation]] weightings in October 1999. The base date for the BUX is 2 January 1991 and it was started from a base value of 1,000. It is calculated in real-time based on the actual market prices of a basket of shares. The BUX index is also a tradeable index. Its futures and option products are available in BSE's derivatives section.
