  • The AEX closed down 1.55% as losses in Technology, Healthcare and Basic Materials led declines across the benchmark.
  • Top gains came from Magnum Ice Cream Nv (MICCT), Unilever (ULVR) and Universal Music Group (UMG), while major falls were recorded by Prosus (PRX), ASM International (ASMI) and BE Semiconductor Industries (BESI).

Netherlands equity markets finished the trading day lower, with the benchmark AEX retreating 1.55% at the close in Amsterdam. Broad weakness in the Technology, Healthcare and Basic Materials sectors underpinned the downbeat session.

Among the top performers on the AEX, Magnum Ice Cream Nv (AS:MICCT) led gains, rising 2.51% or 0.32 points to finish at 12.89. Consumer staple Unilever PLC (AS:ULVR) advanced 1.51% or 0.74 points to close at 49.39, and Universal Music Group NV (AS:UMG) added 0.59% or 0.12 points to end the day at 19.73.

On the downside, Prosus (AS:PRX) posted the steepest decline among major names, sinking 6.33% or 2.60 points to 38.47 at the close. The stock moved to 52-week lows during the session. Semiconductor and equipment stocks also weighed on the index: ASM International NV (AS:ASMI) fell 5.89% or 52.40 points to close at 838.00, while BE Semiconductor Industries NV (AS:BESI) dropped 4.40% or 11.50 points to 249.80.

Decliners outnumbered advancers on the Amsterdam exchange by 66 to 32, with 10 issues ending unchanged.

Measured volatility in AEX options, as reflected by the AEX Volatility gauge, was stable, showing no change and remaining at 21.09.

Commodities saw divergent moves during the session. Crude oil for June delivery climbed 3.60% or $3.53 to $101.60 a barrel, while Brent for July delivery rose 3.37% or $3.51 to $107.72 a barrel. By contrast, the June Gold Futures contract fell 1.08% or $50.98 to trade at $4,677.72 a troy ounce.

Currency pairs moved modestly: EUR/USD was reported unchanged at 0.41% to 1.17, and EUR/GBP was unchanged at 0.24% to 0.87. The US Dollar Index Futures increased 0.44% to 98.25.


This session's price action reflected concentrated selling in technology-related names and a mixed backdrop in commodities and currencies. Market breadth favored decliners and a large-cap fall in Prosus contributed materially to the AEX's decline.

Risks

  • Further weakness in large-cap technology and semiconductor stocks could continue to pressure the AEX and related market segments.
  • Elevated and rising oil prices pose cost and inflation considerations for materials and industrial sectors represented on the index.
  • A significant drop in a major holding, such as Prosus which hit 52-week lows, increases concentration risk for the benchmark and could exacerbate index-level volatility.
