BIST 100 Index — Level, Chart & Constituents

What the BIST 100 measures

The BIST 100 is a stock market index that tracks the performance of the 100 largest companies listed on the Turkish stock exchange. As a broad index, it reflects the overall direction of the Turkish equity market and is denominated in TRY. It is part of the European regional landscape alongside peers such as the PSI (PSI 20), the OMX Copenhagen 25, the FTSE 100, the BEL 20, the Euro Stoxx 50, the FTSE/ATHEX Large Cap, and the WIG20.

Key numbers explained

• The current BIST 100 level is 12,899.35 points, which is the index's valuation at the latest calculation; it is read like a scoreboard, not a price.
• Today's trading range was 12,840.2 to 12,996.53, showing the intraday low and high.
• The price change today is +0.09%, a small positive move over the session.
• Over the last 52 weeks, the index has ranged from a low of 10,053.7 to a high of 15,204.9, illustrating the spread of recent returns.
• The index is denominated in TRY, so currency movements against the Turkish lira can affect returns for investors using other currencies.
• The index is a market-capitalisation-weighted aggregate, meaning larger companies have a greater influence on its level.

What to watch

Investors typically monitor the BIST 100 in the context of Turkish monetary policy, inflation data, and corporate earnings releases from its largest constituents. Broad factors such as interest rate changes, commodity price swings, and global risk sentiment can influence the level of any equity index. Because the BIST 100 is a regional benchmark, its movements are often compared with those of the PSI (PSI 20), the FTSE 100, and the Euro Stoxx 50 to understand relative European performance.
