"An Incomprehensible Snowball": Why Tomer Avnon's Defense Stock Lost 50% in a Week

Autonomous, a defense company controlled by Tomer Avnon, saw its stock plunge 52% last week with no report of an unusual event. Bond yields soared to 46%. CEO Roy Riftin attributes the declines to sales by an institutional entity holding bonds and to political developments in the US.

Autonomous, a small defense company controlled by Tomer Avnon, lost about 52% of its value last week, reflecting a company valuation of only about 20 million shekels. Meanwhile, the company's bond yields (Series A) soared to 46%, reflecting investor distrust. The company issued an unusual report stating that no unusual event had occurred in its business, but the announcement did not lead to a recovery. CEO Roy Riftin said that a certain entity in the market that held a significant amount of bonds began selling, which led to the spread of rumors. According to him, the declines were also influenced by negative sentiment in the Israeli defense stock market amid political developments in the US. Autonomous arrived on the stock exchange in June 2025 after a merger with the Technoplus Ventures shell, and since its peak in July 2025, the stock has lost about 90% of its value. The company ended the first half of 2026 with revenues of 6.9 million shekels and a net loss of 3.9 million shekels.
