RBLD volume surges 47x as Twilio, CoreWeave rally

First Trust Alerian US NextGen Infrastructure ETF (RBLD) has seen unusual trading volume, which is 47× higher than its average daily volume.

Among its largest positions, Twilio has been in focus after RBC Capital reiterated a Sell rating with a $120 price target even as the broader analyst consensus remains at Moderate Buy, and the stock has recently surged on optimism around profitability and raised price targets from other firms. CoreWeave, another key holding, is drawing attention ahead of its upcoming earnings as Wall Street forecasts revenue to more than double despite ongoing losses, while the company lines up major AI cloud deals and a $3.1 billion GPU‑backed loan to expand capacity for customers like OpenAI and Meta. Infrastructure names nVent Electric, Talen Energy, Nucor, and MasTec have also seen fresh catalysts, including raised guidance and multiple target hikes for nVent tied to AI data center demand, a strong earnings and cash‑flow outlook at Talen, robust but increasingly fully valued fundamentals at steelmaker Nucor, and a wave of higher analyst price targets on MasTec that underscore confidence in its growth pipeline.
