On August 19, 2025, Amer (AS) closed with a 4.69% decline, trading at a daily volume of $0.48 billion—up 80.14% from the prior day and ranking 195th in market activity. The drop came amid heightened geopolitical tensions as Russia launched its largest August attack on Ukraine, involving 270 drones and 10 missiles. The Ukrainian air force reported 40 drones and four missiles hitting 16 locations, including a refinery and hospital fires in Volgograd, though no casualties were confirmed. This escalation occurred shortly after U.S. President Donald Trump hosted Ukrainian President Volodymyr Zelenskyy and European leaders in Washington for peace talks, raising market uncertainty about regional stability and trade flows.

Trump’s meeting with Zelenskyy followed a contentious summit with Russian President Vladimir Putin in Alaska, where Putin rejected immediate ceasefire demands and insisted on territorial concessions in eastern Ukraine. During the Washington discussions, Trump hinted at supporting bilateral and trilateral negotiations between Zelenskyy and Putin but avoided committing to NATO troop deployments or security guarantees for Ukraine. European leaders, including French President Emmanuel Macron and German Chancellor Friedrich Merz, emphasized the need for a full ceasefire before peace talks but acknowledged unresolved disputes over territorial claims. The lack of concrete progress in diplomatic efforts contributed to a risk-off sentiment, weighing on equities sensitive to global supply chains and energy markets.

Amer’s sharp decline mirrored broader market concerns over prolonged conflict disrupting key industries. The company’s exposure to European markets and reliance on stable logistics networks heightened vulnerability to geopolitical shocks. Analysts noted that while Trump’s alignment with Zelenskyy on potential security arrangements offered some optimism, the absence of binding commitments left investors cautious. The overnight Russian strikes further underscored the fragility of peace negotiations, with Macron warning that Putin’s strategy hinges on territorial gains. These dynamics created a volatile environment for stocks tied to international trade, exacerbating short-term volatility in Amer’s shares.

The strategy of buying the top 500 stocks by daily trading volume and holding them for one day from 2022 to now delivered moderate returns. The 1-day return was 1.98%, with a total return of 7.61% over the past year. While the strategy showed stability, the returns were modest, and the Sharpe ratio was low at 0.71, indicating modest risk-adjusted returns.
