RWL.AX Rubicon Water ASX pre-market volume spike 25 Mar 2026: short-term trade cue

RWL.AX stock opened pre-market at A$0.125 after a sharp volume surge to 2,885,775 shares, about 85.80x its average volume. The large trade flow pushed the price down 19.35% from yesterday’s close of A$0.155, signalling a volume-driven move rather than steady selling. This spike follows Rubicon Water Limited’s H1 FY26 update that highlighted US project delays and stronger European demand, which traders are re-pricing in early trade on the ASX.
