The breadth of the rally on Borsa Istanbul has expanded significantly in the first seven months of 2026, with the number of advancing stocks overtaking decliners across all major indices.
According to data compiled by Matriks Haber, this positive trend is evident in the BISTTÜM, BIST100, BIST50, and BIST30 benchmarks, marking a notable shift in market participation.
This broadening of gains suggests that investor sentiment is moving beyond a narrow set of large-cap leaders.
The data indicates that market participants are becoming more selective, identifying opportunities across a wider segment of the listed universe rather than concentrating solely on the most liquid names.
Such breadth is often a precursor to sustained market strength, as it reflects deeper conviction among buyers.
The development comes as Turkish equities have maintained a positive trajectory despite broader macroeconomic uncertainties.
