Pre-market trend | Zeta Global (ZETA) surged over 11% on May 18 with significant volume, is the short-term explosive power astonishing?

Yesterday's closing saw Zeta Global's stock price surge by 11.63%, marking the strongest single-day performance in recent times, with the 5-day moving average being strongly broken through and significantly rising. The MACD daily line confirmed a bullish signal above the zero axis, combined with a double-digit increase and a noticeable expansion in trading volume, which typically indicates a significant positive change in market expectations regarding the company's fundamentals or industry logic. The trading volume reached USD 322 million, and the influx of funds is not to be underestimated, with a clear dominance of bulls in the market. On the news front, Zeta Global, as an AI-driven marketing technology platform, is at the forefront of the industry trend. Goldman Sachs' latest research report emphasizes that improvements in AI productivity are the most critical macro variable at present, and Zeta Global's core business—using AI technology to help companies accurately reach consumers—happens to be at the forefront of this narrative. In the same sector, LiveRamp (RAMP) saw a staggering increase of 27% yesterday, with application software, especially in the AI-related MarTech space, becoming the focus of capital pursuit. The technology software ETF (IGV) rose by 1.19% yesterday, but Zeta's performance far exceeded the sector average. From a technical perspective, the 11% increase has pushed the stock price significantly above the short-term moving average, resulting in a large deviation, indicating the possibility of a technical correction in the short term. However, from the perspective of volume-price coordination, the signal of a volume-driven rally is relatively healthy, indicating that the rise is driven by real funds rather than a temporary rebound from short covering. The key observation point is whether the trading volume can remain active in the subsequent trading days
