The humanoid robot company Yushu Technology (688836.SH) announced that the cumulative price deviation of the company's stock closing price has exceeded 30% over three consecutive trading days, which falls under the category of abnormal stock trading fluctuations. As of October 26, 2026, the company's rolling price-to-earnings ratio is 465.22 times, significantly higher than the average rolling price-to-earnings ratio of 38.54 times in the general equipment manufacturing industry.The announcement pointed out that the humanoid robot industry is still in the early stages of commercialization, with uncertainties in technology maturity, cultivation of downstream market demand, and supporting capabilities in the industrial chain. The transition of physical AI technology from laboratory demonstrations to large-scale implementation in real-world scenarios still faces challenges such as perception accuracy, motion control stability, data accumulation, and hardware-software collaboration. The maturity of the technological path and business model still requires time for validation. If the industry's large-scale commercialization progress does not meet expectations, the company's future revenue expansion and performance release may be adversely affected, posing investment risks of valuation regression.

CryptoQuant certified analyst Trader_Gemini stated that the Trader On-chain Realized Price has risen again, currently becoming an important reference indicator for observing the subsequent trend of BTC. This indicator reflects the average acquisition price of BTC that last transferred in the past 1 to 3 months and can be used to measure the average holding cost of recent market participants. Currently, the trading price of BTC is in the low range of $80,000, while the realized price for traders has risen to the mid-range of $70,000, indicating that the current price of BTC is still above the recent average cost for traders.From the current structure, recent market participants are generally still in a state of unrealized profit, and the short to medium-term cost structure remains relatively positive. Historically, when the market is in an upward phase, the realized price for traders often provides support when BTC retraces close to that level. If the price can hold above this cost line, it indicates that the holding cost for recent participants may still provide support for the market; conversely, if BTC falls below this level, some traders in an unrealized loss state may sell when the price rebounds close to their cost, turning that position from support to resistance.In addition, Trader_Gemini also reminded to pay attention to the Upper Band of the indicator. Historically, when BTC prices approach the upper band, it is often accompanied by increased profit-taking pressure, which may lead to a short-term pullback. Therefore, if BTC continues to rise, the market reaction near the upper band is worth close observation; if BTC experiences a pullback, attention should be paid to whether the realized price for traders can provide effective support. Trader_Gemini emphasized that the upper band does not necessarily mean the market will peak, and the realized price for traders does not guarantee that BTC will rebound; neither should be viewed as automatic triggers for trading but rather as reference indicators for judging at what price recent market participants may change their behavior. Currently, BTC is still operating above the realized price for traders, and the overall cost structure remains positive; if a deeper adjustment occurs later, whether this indicator can continue to provide support will become an important observation point.
