The BIST 100 stock index finished the latest completed session at 11,165.44 points on Wednesday, October 28, according to Bilginet. The benchmark rose 0.13% from the previous close in a shortened trading session ahead of Republic Day.
Half-day trading limits market signals
Share-market trading ended at 12:30 local time, followed by the closing session through 12:40, the report said. Total turnover reached 49.3 billion Turkish lira. The banking index fell 1.60%, while the holding index declined 1.47%.
Mining was the strongest-performing sector index, rising 1.66%. Financial leasing and factoring was the weakest, falling 2.92%. These sector moves indicate that the modest index gain was not broad-based across the main market groups.
Global backdrop and holiday break
Bilginet cited a positive tone in global markets, supported by technology stocks, while investors also focused on the US Federal Reserve's interest-rate decision. The report did not establish a direct causal link between those developments and the BIST 100's closing move.
Borsa Istanbul identifies the BIST 100 as the XU100 benchmark index, denominated in Turkish lira. The exchange was closed on Thursday, October 29, for Republic Day, so there was no new regular-session close for that date. Trading is scheduled to resume on Friday, October 30.
For investors, the next session will provide the first regular opportunity to assess whether the half-day gain can broaden beyond the strongest sectors. The key levels cited in the report were resistance at 11,300 and 11,400 points and support at 11,000 and 10,900 points; these are market reference levels rather than forecasts.
