DOTW.SW WisdomTree Polkadot on SIX +23.32%: thin-volume move raises risk

DOTW.SW stock jumped 23.32% to CHF 0.6674 at market close on 18 Mar 2026 on the SIX exchange in Switzerland. The move stands out because trading volume was only 3 shares versus an average of 112, so price action reflects thin liquidity more than broad demand. Investors should treat this as a short-term spike tied to ETP mechanics and Polkadot underlying flows, not a broad market endorsement.
