Richtech Robotics shares plunge 7.95% amid sector-wide selloff and year-end market caution

Richtech Robotics shares fell 7.95% in pre-market trading on Dec. 29, 2025, marking the largest intraday decline in its recent trading history. The sharp drop came amid broader market volatility and heightened investor caution ahead of year-end portfolio rebalancing, though no company-specific catalysts were immediately disclosed.

The selloff aligns with a sector-wide selloff in robotics and automation stocks, as investors reassessed long-term growth prospects against a backdrop of softening industrial demand and regulatory uncertainties.

Analysts noted that the decline could reflect profit-taking following a recent rally, though the magnitude suggests deeper concerns about near-term execution risks.

With no material news or earnings reports released in the preceding 48 hours, the move appears primarily driven by macroeconomic factors rather than fundamental company developments. Market participants are now closely watching for follow-through selling pressure or signs of stabilizing volume patterns ahead of the opening bell.

Further analysis suggests that the current decline could be part of a larger bearish pattern emerging in the broader market, particularly as December end-of-year portfolio adjustments continue to influence short-term sentiment. While there are no clear, identifiable technical patterns such as a bearish engulfing or death cross triggering the decline, broader macroeconomic conditions may continue to weigh on stock performance in the near term.
