On July 31, shares of storage industry leaders GIGADEVICE and 德明利 both opened at their daily upper price limits, forming a "one" character pattern, before subsequently breaking open during the trading session.

Initially, both stocks were locked at the 10% gain limit, demonstrating strong early momentum. However, the limit-up orders were later overwhelmed by selling pressure, causing the stocks to retreat from their highs and triggering a "blown limit" scenario where the price limit was temporarily broken.

The dual surge and subsequent fade highlights the volatile sentiment in the semiconductor storage sector, with investors showing both enthusiasm for the sector's potential and caution regarding current valuations.
