BIST 100’s 2026 Mid‑Year Earnings Season: A New Pivot for Market Dynamics

The Istanbul Stock Exchange has officially opened the calendar for the 2026 mid‑year earnings releases, instantly shifting investors' focus to a high‑volatility zone.

Earnings Calendar: When Are the Companies Reporting?

The 30 large‑cap constituents of the BIST 100 will disclose results between May 15 and July 30. Historically, this window has generated an average 3.2% index movement.

■Banking sector: 15 banks anticipate a 1.8% rise despite narrowing interest margins and credit growth.

■Energy & petrochemicals: 7 firms expect a 0.9% net profit increase even with a 12% dip in global oil prices.

■Technology & telecom: 5 companies target 4.5% revenue growth and a 2.3% EBITDA margin.

■Retail: 3 major retailers plan to offset a softening consumer spend with a modest 1.2% sales decline.

Technical Landscape: What Do Fibonacci Retracements and Ichimoku Clouds Reveal?

The BIST 100 is currently undergoing a 61.8% retracement towards the 38.2% level. Ichimoku clouds indicate that maintaining the Kijun‑Sen at 5,400 points supports a continued uptrend.

■The 50‑Day EMA remains above 5,350, reinforcing short‑term buying pressure.

■The 200‑Day EMA has risen 0.5% above 5,200, forming a medium‑term support line.

■The RSI (14) sits at 58, suggesting a consolidation phase before any over‑bought conditions emerge.

Liquidity Flow: Foreign Capital and Fund Positions

Net foreign inflows into the BIST 100 are steady at $1.2 billion, while net short positions from overseas investors have fallen 3.4%.

■Eurobond holdings have climbed 6.7% to $3.8 billion.

■ETF inflows added a net $450 million, bolstering index liquidity.

■Short‑term futures volume surged 9.1%, reaching 15.2 million contracts.

Caner Yılmaz – Director of Technical & Quantitative Analysis, BIST 100:

For the first half of 2026, the BIST 100 sits firmly in a “high‑probability uptrend” zone from a technical standpoint. The Fibonacci‑Ichimoku confluence suggests that as long as the Kijun‑Sen stays above 5,400, the index could push toward 5,600. However, a rise in the RSI toward 70 could trigger a short‑term pullback; a breach of the 50‑Day EMA would raise stop‑loss activation risk. Portfolio managers should consider constructing a “risk‑pay” between the 38.2% and 61.8% retracement levels to manage volatility while capturing upside opportunities.
