What's driving this? Well, the BIST 100 seems to be defying the broader trend, showing remarkable strength since the start of the year. While precious metals like gold and silver, and even global stock markets, have been reacting nervously to geopolitical tensions, Borsa Istanbul has managed to attract attention in a positive way. It's a good sign, suggesting underlying confidence in the Turkish market.

The index closed out the final week of January 2026 at an impressive 13,838.29 points, marking the end of a very strong month where it rose by a whopping 22.88%. It's interesting to note that the upward momentum faltered slightly on Thursday, a day later than the previous two weeks, but it still managed to maintain its overall trajectory, consistently hitting new historical peaks. The week saw it dip to a low of 12,886.22 and climb to a high of 13,906.51 points, showcasing the volatility even within its upward climb.

Leading the charge in terms of individual stock gains was Kiler Holding, with a staggering 33.79% increase. Akbank followed with a solid 17.88% gain, and Enka Construction rounded out the top three with a respectable 16.35% increase. It seems that investor confidence is concentrated in specific sectors, especially considering that the banking index overall gained 10.5%, the holding index rose 9.42%, and the industrial index increased by 4.74%. Not everyone enjoyed the rally though; Gen Ilac (GENIL) took the biggest hit, falling 11.53%, followed by Pasifik Eurasia (PASEU) and Pasifik Teknoloji (PATEK), down 6.66% and 6.40% respectively.

Looking at the heavyweights, ASELSAN (ASELS) remains the company with the highest market value on Borsa Istanbul, clocking in at a massive 1 trillion 382 billion 820 million TL. Kiler Holding (KLRHO) moved into second place with a valuation of 958 billion 750 million TL, while Garanti BBVA (GARAN) held its ground in third, valued at 677 billion 460 million TL. This highlights the significant influence these companies have on the overall market sentiment.

While trading volume hit records on some days last week, the overall weekly volume did see a slight dip to just over 930 billion 795 million TL. Turkish Airlines (THYAO) topped the list of most actively traded shares within the index, with a volume of 87 billion 119 million TL. Aselsan (ASELS) wasn't far behind with 78 billion 452 million TL, and Is Bankasi (ISCTR) rounded out the top three with a trading volume of 56 billion 211 million TL. All in all, a fascinating week for Borsa Istanbul, and one that will undoubtedly be closely watched in the coming weeks.
