Webtoon Stock Soars 81.2% on $240M Volume Spike Ranks 482nd in Market Activity

On August 13, 2025, Webtoon (WBTN) surged 81.20% with a trading volume of $240 million, marking a 1,445.68% increase from the previous day’s volume. The stock ranked 482nd in trading activity across the market, reflecting heightened investor interest.

The significant pre-market movement suggests strong reactions to undisclosed catalysts, as early trading activity often signals responses to news or sector-specific developments. While no direct company announcements were cited in available reports, the abrupt volume spike indicates potential liquidity inflows or strategic positioning by traders capitalizing on market sentiment shifts.

A backtested strategy of holding the top 500 most actively traded stocks for one day generated a 3.77% return from 2022 to present. This outperformed a passive market baseline of the same return, though risks persist due to volatility and liquidity constraints. The performance underscores the potential but underscores the importance of contextual market analysis when deploying volume-driven trading strategies.
