News that Russia and Ukraine had agreed to a ceasefire from May 9 to 11, along with rumors of a possible freeze in the conflict, triggered a sharp reaction on the stock market. Shares of major Western defense companies began to fall noticeably.

Investors quickly responded to the prospect of reduced fighting and started selling off stocks in companies whose profits are closely tied to the continuation of the military confrontation in Ukraine. Ukrainian media observers noted that market data showed a rapid decline in the value of several major defense industry players.

The hardest hit was AeroVironment, a company specializing in the production of various drones. Its shares lost more than half their value.

Lockheed Martin, one of the leading global arms manufacturers, also came under pressure. The corporation produces multiple-launch rocket systems and other weapons in high demand on the battlefield. Its stock fell by around 25 percent.

The market reaction may point to a clear shift in sentiment among traders. Investors no longer appear to be pricing in a scenario of prolonged escalation in the near term. Instead, they are beginning to factor in the possibility of a freeze in hostilities, or even the end of the conflict’s active phase.

Russian President Vladimir Putin, speaking to journalists on May 9, said the conflict in Ukraine was moving toward its conclusion.
