Istanbul shares retreat as heavy losses in insurance, retail and machinery weigh on BIST 100

Turkey's main equity gauge, the BIST 100, closed lower after Monday's session, dragged down by weakness in Insurance, Wholesale & Retail Trade and Metal Products & Machinery sectors. Market breadth favored decliners, while a handful of smaller-cap names posted double-digit percentage gains. Commodities and currency pairs also showed notable moves.

Key Points

  • BIST 100 closed down 1.04% as selling was concentrated in Insurance, Wholesale & Retail Trade and Metal Products & Machinery sectors.
  • Market breadth favored decliners: 368 stocks fell, 232 gained, 18 unchanged; several small-caps recorded double-digit percentage gains.
  • Commodities and FX moved notably: April gold futures fell 1.30%, May crude lost 2.61%, USD/TRY eased slightly while EUR/TRY rose.

Turkey's stock market ended the trading day in negative territory on Monday, with the BIST 100 index closing down 1.04% in Istanbul as losses in several cyclical and consumer-related sectors pressured the overall market.

Market breadth leaned towards selling pressure: 368 stocks fell versus 232 advancers, and 18 issues finished unchanged.


Top performers

  • Reeder Teknoloji Sanayi Ve Ticaret AS (IS:REEDR) led gains on the BIST 100, climbing 9.98% - a rise of 0.61 points to finish at 6.72.
  • Katilimevim Tasarruf Finansman AS (IS:KTLEV) rose 9.96%, gaining 5.50 points to close at 60.70. The stock reached an all-time high in the session.
  • Oba Makarnacilik Sanayi ve Ticaret AS (IS:OBAMS) added 5.88%, up 0.45 points to 8.10 by the close.

Largest decliners

  • Kiler Holding AS (IS:KLRHO) was the weakest name among the large fallers, sliding 9.97% - a decline of 17.70 points to 159.80 at the close.
  • Efor Yatırım Sanayi ve Ticaret A.Ş. (IS:EFOR) dropped 9.96%, down 1.71 points to 15.46.
  • Fenerbahce Futbol AS (IS:FENER) lost 7.48%, falling 0.22 points to end the session at 2.72; the shares moved to 52-week lows.

Commodities and currency moves

Precious metals and energy contracts also moved lower during the trading day. Gold Futures for April delivery slipped 1.30%, a decline of 65.60, to settle at $4,996.10 per troy ounce. In the oil complex, May crude oil fell 2.61% or $2.53 to $94.31 a barrel, while the May Brent contract dropped 0.96% or $0.99 to $102.15 a barrel.

On the currency front, the Turkish lira showed small mixed moves versus major pairs. USD/TRY eased 0.04% to 44.18, while EUR/TRY rose 0.71% to 50.82. Meanwhile, US Dollar Index Futures were down 0.48% at 99.63.


Implications for sectors

The session's dispersion - with significant declines in Insurance, Wholesale & Retail Trade and Metal Products & Machinery - points to sector-specific selling pressure even as select smaller-cap names posted strong gains. Market participants may watch whether the narrow rallies in names such as KTLEV and REEDR broaden or remain isolated.

Overall, the market closed with a clear bias toward declines, leaving the BIST 100 lower by 1.04% at the end of Monday's trading.

Risks

  • Sector-specific weakness in Insurance, Wholesale & Retail Trade and Metal Products & Machinery could pressure related equities and investor sentiment in those sectors.
  • Large declines in individual stocks such as Kiler Holding, Efor and Fenerbahce may increase volatility for sector indices and small-cap segments.
  • Commodities and currency swings - including falling oil and gold prices and lira movement versus USD and EUR - add uncertainty to costs and foreign-currency exposures for Turkish companies.
