Ford Otomotiv Sanayi AS (IS:FROTO) retreated 4.84%, or 6.50 points, to finish at 127.80, and SASA Polyester Sanayi AS (IS:SASA) fell 4.69% - down 0.13 points - to 2.64.


Advance-decline breadth and market breadth

Rising issues slightly outnumbered decliners on the Istanbul Stock Exchange, with 306 stocks higher versus 289 lower, and 15 ending the session unchanged.


Commodities and currencies

Across commodities, Gold Futures for April delivery moved lower, down 3.27% or 165.09 to $4,881.21 a troy ounce. Crude oil for April delivery fell 1.16% - a decline of 0.73 - to reach $62.02 a barrel, while the April Brent contract dropped 2.26% or 1.55 to trade at $67.10 a barrel.

Context and closing note

The session displayed a split market where a small set of stocks posted strong gains, including an all-time high print for Destek Finans Faktoring As, while headline sectors tied to metals and petrochemical activity pulled the benchmark lower. Commodity declines in precious metals and crude coincided with mixed FX moves as the BIST 100 finished the day down 0.78%.

Risks

  • Concentration of selling in Basic Metals, Metal Products & Machinery, and Chemical, Petroleum & Plastic sectors could exacerbate benchmark declines if weakness persists - this primarily affects industrial and petrochemical market segments.
  • Commodity price drops, including a 3.27% fall in April Gold Futures and declines in crude oil and Brent, may influence related sectors and investor sentiment in resource-linked equities.
  • Currency moves - a 0.05% rise in USD/TRY and a 0.33% decline in EUR/TRY - introduce FX-related pressures for companies with foreign-currency exposures, notably exporters and importers.
