Deep Analysis

1. Market Summary and Overview

As of 25 September 2026, Friday, at 23:48, the BIST 30 (XU030) index closed at 15.946.95, recording a daily 0.04% increase versus the previous close of 15.940.38; the BIST 100 (XU100) stood at 15.947, up 0.09% versus the previous close of 15.947. The USD/TRY rate rose 0.16% from 48.85 to 48.93, causing this marginal rise in TL terms to turn into a 0.12% erosion in dollar terms. This divergence reveals that the index’s flat trajectory in TL terms actually masks a foreign‑currency‑based value loss when exchange‑rate movements are stripped out. Although daily volume data is not provided, the index’s compression in the 15.940‑15.950 band and its negative dollar‑based performance indicate that the market is searching for direction and that buying power remains limited to exchange‑rate‑driven speculative attempts. Looking at the sector level, strong buying signals appear in the Kardemir (KRDMD) and Tofaş (TOASO) groups, while selling pressure dominates in the Banking (GARAN, AKBNK, YKBNK, ISCTR, VAKBN), Aviation (THYAO, PGSUS, TAVHL), Aselsan (ASELS), Holding (SAHOL, KCHOL) and Retail (MGROS, BIMAS) groups; the concentration of "STRONG SELL" in the bank and aviation stocks that form the index’s weight center is seen to cap the index’s upside. On the macro front, Turkey’s annual inflation at 31.51%, the policy rate held at 37.0%, and still‑limited real‑rate expectations explain the BIST 30’s relative resilience in dollar terms versus the XU100 (−2.74%) and XU030 (−2.62%) historical performance, yet they do not create sufficient conditions for a sustainable trend reversal.

2. Sector-Based Evaluation

"Heat map data and signal intensity show sectors are exhibiting clear polarization."Metal & Mining In the sector, KRDMD's "STRONG BUY" (Technical: Short/Medium/Long BUY, WT BUY, Channel 54%, r=0.77; Oscillator: STRONG BUY, RSI 57.9, MACD 0.59, ADX 17.4) and EREGL's "SELL" (Technical: Medium SELL, WT BUY, Channel 65%, r=-0.71; Oscillator: SELL, RSI 48.0, ADX 14.7) signals show divergence; KRDMD's 20.0% return over 60 days and strong trend structure (Pearson 0.77) clearly proves that Kardemir is the locomotive of the sector.Automotive In the sector, while TOASO is "BUY" (Technical: Short BUY, Long BUY, WT BUY, Channel 80%, r=-0.28; Oscillator: STRONG BUY, RSI 55.6, MACD 2.14), FROTO gives a "STRONG SELL" signal (Technical: All periods SELL, WT SELL, Channel 38%, r=-0.46; Oscillator: STRONG SELL, RSI 44.7, ADX 23.5), showing that export-focused TOASO is taking better advantage of the currency advantage (USD/TRY +0.16%) compared to FROTO.Energy & Petrochemicals In the group, TUPRS "NEUTRAL" (Technical: Medium/Long BUY, WT SELL, Channel 4%, r=0.95; Oscillator: BUY, RSI 56.5, MACD 12.2, ADX 28.0) and PETKM "SELL" (Technical: Long BUY, WT SELL, Channel 34%; Oscillator: SELL, RSI 47.4) divergence, with TUPRS consolidating within a strong trend (r=0.95) at the lower boundary of its regression channel (4%), indicates that PETKM is losing momentum.Banking The sector is completely under seller control; GARAN (Oscillator: 0 Buy / 19 Sell, RSI 47.7, CCI -53.6), AKBNK (3/15, RSI 49.3, CCI -35.1), YKBNK (3/16, RSI 49.5, CCI -17.1), ISCTR (2/18, RSI 48.3, CCI -25.3) "STRONG SELL", while VAKBN is trying to catch a weak positive divergence with Technical "NEUTRAL" / Oscillator "AL" (12/8, RSI 51.5).Aviation & Transportation The group THYAO, PGSUS, TAVHL are all in the "SELL/STRONG SELL" zone; THYAO's strong downtrend with Channel 72%, r=-0.90 and Oscillator ADX 24.7 confirms that the sector is under pressure from fuel costs and currency risk.Chemicals & FertilizersIn the sector, GUBRF "SELL" (Technical: Medium SELL, WT BUY, Channel 35%; Oscillator: NEUTRAL, RSI 49.8, ADX 29.1) and SASA "STRONG SELL" (Technical: All SELL, Channel 1%, r=-0.08; Oscillator: STRONG SELL, RSI 33.5, CCI -114, ADX 20.5) are in the oversold area (RSI 33.5, Stoch 3.8), but ADX is expected to fall below 20 for the trend to weaken.RetailBIMAS is rated as "NEUTRAL" (Technical: Medium/Long BUY, WT SELL, Channel 41%, r=0.87; Oscillator: BUY, RSI 54.8, MACD 6.3) while MGROS has a "STRONG SELL" rating (Technical: All SELL, Channel 66%, r=-0.90; Oscillator: STRONG SELL, RSI 41.8, MACD -11.6, ADX 32.9). The structural difference arises because BIMAS maintains a strong trend (r=0.87) at the middle of the channel (41%), whereas MGROS experiences a trend break (r=-0.90) above the channel (66%).

3. Technical Visual Analysis

Reading EMA sequences, Wave Trend (WT) and regression channel positions along with Pearson correlation coefficients clarifies the structural deterioration under the index at the stock level.KRDMD, In all three timeframes (Short/Medium/Long), the EMA sequence being in "BUY" position, WT giving a "BUY" signal, and the price trading near the upper mid-band of the regression channel (54%) with a high Pearson correlation (r=0.77) proves that the trend continues in a direction that is both directional and statistically significant; this structure strengthens the probability that it will continue until the price approaches the upper channel band (100%).TOASO, Although showing slight hesitation with "BUY" in Short and Long term and "WAIT" in Medium term, WT "BUY" signal and the channel position at 80% level (near resistance) indicate that the price is testing the upper channel limit; however, the negative and low Pearson r=-0.28 suggests this movement is an intra-channel fluctuation and indicates a weak or non-directional trend; therefore, a pullback (towards the middle of the channel) from the 80% level is highly likely.TUPRS, Despite the "BUY" EMA sequence in Medium and Long term, WT gives a "SELL" signal and the price is far below the channel (4%); here, the extremely high positive r=0.95 value shows that the price is moving in strong alignment with the channel (linear trend) but sticking to the lower band; this situation suggests that the trend continues but the risk of overselling/sub-channel (mean reversion) is high, and the WT SELL signal could be an early warning of this risk.THYAO, PGSUS, MGROS, SAHOL, SISE, GARAN the common denominator in stocks that provide a "STRONG SELL" signal such as EMA sequences showing "SELL" (or Short Sell/Medium Sell/Long Sell) across all three timeframes, WT "SELL", and channel positions in the 60-70% band (THYAO 72%, PGSUS 61%, MGROS 66%, SAHOL 18% -below channel-, SISE 38%), along with Pearson r values being strongly negative (THYAO -0.90, MGROS -0.90, TCELL -0.76, EREGL -0.71) or very low positive (SAHOL 0.31, GARAN 0.40); this structure confirms that these stocks are moving toward the lower band of their regression channels (or the middle band of a new descending channel after a breakdown), indicating a statistically strong and directional trend (high |r|).BIMAS andVAKBN whereas technical "NEUTRAL" (Medium/Long Buy, Short Wait) with oscillator "BUY" and channel positions at 41-46% (middle band), Pearson r at 0.87 and 0.65, shows they are consolidating within a strong positive trend, and a wait strategy is valid until direction is determined (Short EMA Buy or WT Buy).DSTKF' the dramatic structural breakdown (60g -69.2%, Channel 26%, r=-0.50, WT SELL, Oscillator STRONG SELL, RSI 24.4, CCI -178, ADX 26.7) proves that the stock is experiencing a liquidity crisis or a fundamental deterioration, and that technical indicators are only following this collapse (not warning in advance).

4. Oscillator and Momentum Readings

TradingView oscillator data quantifies the momentum status and overbought/oversold risks on a stock-by-stock basis.KRDMD' the combination of RSI 57.9 (above neutral zone), StochK 79.3 (near overbought threshold), CCI 95.5 (positive momentum), MACD 0.59 (positive histogram) and ADX 17.4 (weak trend strength) indicates the price is rising but the trend strength (ADX<20) has not yet confirmed a strong trend, while the Stochastic carries a short-term cooling/pullback risk (above 80); this situation should be resolved with progress toward the upper channel band (100%) in the Base Scenario, and with strengthening trend (ADX closing above 20) as a condition in the Optimistic Scenario.TOASO' RSI 55.6, StochK 57.5, CCI 58.0, MACD 2.14 and ADX 15.6; while momentum indicators stay in positive territory, ADX staying below 20 indicates the trend is "directional but weak", with the price likely consolidating or pulling back slightly at the upper channel band (80%) to await an ADX rise.TUPRS' RSI 56.5, MACD 12.2 (strong positive), StochK 66.1, CCI 19.3 and ADX 28.0; ADX above 25 confirms a strong trend, while the high positive value of MACD proves momentum continues; however, WT "SELL" and Channel 4% position suggest this strong trend is being tested at the channel lower boundary with a high probability of mean reversion (return to the channel center at 50% level).Banking Group ( GARAN, AKBNK, YKBNK, ISCTR) show systematic weakness in oscillators: RSI in 47-49 band (below neutral), MACD around/below zero line (GARAN -0.0, AKBNK 0.27, YKBNK 0.09, ISCTR 0.1), CCI negative (GARAN -53.6, AKBNK -35.1, YKBNK -17.1, ISCTR -25.3), StochK in 46-73 range (GARAN 66, AKBNK 64, YKBNK 73, ISCTR 46), ADX in 17-20 band (weak-trend). This picture shows banking stocks are in a "drift down" formation, with no directional trend yet (ADX<20) but momentum (CCI, MACD, RSI) starting to shift in favor of sellers; VAKBN meanwhile maintains a neutral-positive structure separate from the group with RSI 51.5, MACD 0.46, CCI -2.5, ADX 18.9.Oversold Stocks: SASA (RSI 33.5, StochK 3.8, CCI -114, ADX 20.5), DSTKF (RSI 24.4, StochK 0.0, CCI -178, ADX 26.7), ASTOR (RSI 39.0, StochK 34.9, CCI -71.3, ADX 32.3), TRALT (RSI 47.7, CCI -76.1), PGSUS (RSI 43.1, CCI -102.7). RSI at 30-40, CCI below -100 and StochK below 20 in these stocks create a probability of a technical bounce; however, ADX being in the 20-32 band (SASA, DSTKF, ASTOR, PGSUS) emphasizes the downward trend is still strong and any bounce carries high risk of being a "selling opportunity" (pullback to sell); for actual trend reversal, ADX needs to fall below 20 and RSI must break permanently above 50.Those Carrying Overbought Risk: KRDMD (StochK 79.3), TAVHL (StochK 78.5), THYAO (StochK 70.7), YKBNK (StochK 73.5), MGROS (StochK 67.8). Stochastic above/near 80 levels in these stocks give a short-term overheating signal; however, except for KRDMD, the trend direction is downward (STRONG SELL) in others, so this overbought should be interpreted as a continuation signal after a pullback in the downward trend.

5. Risk Map and Scenarios

Base Scenario (Probability ~55%): Index consolidation at 15.800 - 16.100 Band with Low Volume. The dollar-based -0.12% performance of XU030 and the marginal 0.04% increase in TL terms prove that the market is in "wait-and-see mode". The structural selling pressure in Banking (XU030 weight ~35-40%) and Aviation stocks (STRONG SELL signals, negative Pearson r, ADX>20) prevents the index from making a significant upward move. Selective buying in KRDMD and TOASO supports the bottom of the index but is insufficient to push it up alone. The USD/TRY remaining at the 48.93 level and inflation data (annual 37%) delaying expectations of interest rate cuts lead to limited foreign buying.In this scenario: As KRDMD advances toward the upper band of its channel (80-100%), TOASO pulls back from the 80 resistance and returns to the middle of the channel (50-60%); Banking stocks move sideways/indecisively in parallel with the 15.800-15.900 index levels; TUPRS attempts a mean reversion from the bottom of its channel (4%) toward the middle (50%).
Bullish Scenario (Probability ~4%): Dollar-Based Positive Divergence and Index Breakout Above 16.200. The following concrete conditions for this scenario aretogether (1) USD/TRY must fall below 48,848 (strengthening of TL), (2) Banking stocks (especially GARAN, AKBNK) permanent RSI oscillator breakdown above 50 + MACD zero-line crossover + WT BUY signal, (3) TUPRS's WT SELL signal turning into BUY or price moving to the channel 20%-30 band, (4) US 10Y Treasury yield falling below 5.00 (VIX below 15.64). If these conditions are met, XU030 could target the 16.200-16.500 band; KRDMD new peak (channel breakdown), TOASO trend continuation with channel breakdown.
Pessimistic Scenario (Probability ~31.51%): Downward Below 15.500 Led by Banking Sector. Triggers: (1) Break above USD/TRY 48.848 (TL depreciation rate accelerates), (2) Sustainability above USD 110/barrel for Brent (Pressure on current account, Inflation risk), (3) VAKBN in Banking Shares switching to "SELL" signal (Oscillator BUY -> SELL), (4) StochK closing above 80 on KRDMD + ADX staying below 20 (loss of momentum). In this case, XU030 could test the 15.500-15.300 support zone (reference to past 30-day lows); KRDMD would pull back to channel midpoint (50%), TOASO would fall below channel bottom (40%).
Split Strategy and Position Management: "Stock Picking" (stock picking) index strategy is superior in the current environment. Position size should be adjusted based on signal alignment (Technical + Oscillator) and ADX trend strength. For KRDMD with strong BUY signal, position size should be 100-125% of normal; for TOASO with Technical BUY / Oscillator STRONG BUY alignment (75-100% due to channel 80% resistance); for TUPRS, BIMAS, VAKBN, TTKOM with NEUTRAL/BUY alignment (25-50% for waiting/volume entry). For stocks with STRONG SELL signals (GARAN, AKBNK, THYAO, PGSUS, SAHOL, SISE, MGROS, SASA, DSTKF), partial/used realization in existing long positions or short position (only for ADX>25 and r<-0.70: THYAO, MGROS, TCELL, EREGL) can be considered. Stop levels should be defined as a break of the regression channel lower band (for Long) or upper band (for Short).

6. Recommended Stocks for the Day

The table below contains stocks where the "General" signal in the technical scan data and the "Recommendation" signal in TradingView oscillator dataare both " at the "BUY" or "STRONG BUY" level, meaning stocks receiving dual confirmation. Other stocks in the data (TUPRS, BIMAS, VAKBN, TTKOM) are not included in this table as they give a "NEUTRAL" signal technically.
