Weekly Buybacks Forge a New Support Level on the BIST 100

This week the BIST 100 index posted a 4.2% rise, driven by a surge of corporate share‑buyback activity, delivering the market's most dynamic move of the week.

Price Action Reflected in the Buy‑Back Wave

Corporate buybacks totalling $1.75 billion breached the 38.2% Fibonacci retracement, propelling the index from 7,850 points to 8,120 points. Historically, such volume spikes at these levels have marked the onset of a sustained upward trend.

■8,050 points: above the 50‑day moving average (MA), indicating short‑term buying pressure.

■8,120 points: testing the 61.8% Fibonacci level, a potential new resistance.

■8,200 points: next major resistance, representing the 23.6% retracement of the prior high.

Ichimoku Cloud Clash: Red vs. Green Lines

The Ichimoku cloud (Kumo) spans 8,030 (upper) to 7,970 (lower) points. The buy‑back surge broke above the cloud, with a bullish Tenkan‑sen (9‑period) crossing above the Kijun‑sen (26‑period) at 8,040 vs. 8,010, respectively.

■Tenkan‑sen 8,040, Kijun‑sen 8,010 → bullish crossover.

■Senkou Span A 8,050, Senkou Span B 7,990 → cloud narrowing, indicating reduced volatility.

Momentum Over Averages and Liquidity Drain

The volume‑weighted average price (VWAP) held steady at 8,015 points while trading volume surged 27% versus the prior week, suggesting that buyers are actively consuming liquidity and keeping the price above the cloud's upper bound.

■27% volume increase: deepening market depth.

■VWAP > 8,000: price staying above its average signals continued buying strength.

Portfolio Implications of the Buy‑Back Surge

Institutional investors are boosting their BIST 100 exposure by 1.5%, reshaping the risk‑return profile of their portfolios. Technically, this creates clear short‑term entry points and mid‑term trend‑following opportunities.

■1.5% increase in portfolio weight: modest risk tilt.

■8,100 points: mid‑term target, testable within a 4‑week horizon.

■Stop‑loss: set around 7,950 points to guard against a cloud‑break breach.

When corporate buy‑back programs align with technical indicators, a new support zone on the BIST 100 becomes inevitable. The breach of the 38.2% Fibonacci level, the narrowing Ichimoku cloud, and the uptick in volume all signal sustained buying pressure. These cues present short‑term traders with entry opportunities and mid‑term investors with trend‑following strategies. In particular, a decisive break above 8,100 points would herald the next upward wave. Caner Yılmaz, Technical and Quantitative Analysis Director, BIST 100.
