On July 16, Ambarella declined 8.09% in regular trading, trading at $66.405/share, with turnover of $33.16 million. The edge AI chipmaker saw accelerated losses amid a broad semiconductor sector selloff.

The decline comes as the popular AI-driven strategy of buying chip stocks and selling software stocks shows signs of unraveling. The Philadelphia Semiconductor Index has fallen approximately 12% in July, despite posting its best quarterly performance on record earlier this year with a 78% year-to-date gain. Market participants are reassessing crowded positioning in the semiconductor space, with the sector experiencing its largest single-day relative drawdown on record in recent weeks.

Within the Semiconductors sector, selling pressure was widespread. Among individual stocks, Micron Technology fell 9.65%, Intel fell 7.28%, Advanced Micro Devices fell 6.26%, NVIDIA fell 2.26%, and Taiwan Semiconductor Manufacturing fell 1.38%.

Ambarella had previously reported Q1 fiscal 2027 results in late May that slightly beat estimates, with adjusted EPS of $0.11 versus $0.10 expected and revenue of $100.4 million. The company also announced a long-term Edge AI partnership with Hanwha valued in excess of $800 million in potential revenue.
