# AI narrative spillover combined with fundamentals exceeding expectations, the energy storage battery ETF E Fund (159566) received a net subscription of 23 million shares during the trading session

On April 14th afternoon, the battery sector experienced strong fluctuations. As of 14:10, the CNI New Energy Battery Index rose by 1.5%, and the CSI Battery Theme Index increased by 1.2%. The energy storage battery ETF E Fund (159566) saw a net subscription of 23 million shares during the trading session.

The energy storage sector is benefiting from the dual catalysts of AI narrative spillover and better-than-expected fundamentals. The explosion of AI Agents has accelerated the demand for AI hardware, further opening up the energy storage space for AIDC. With more orders being finalized, the sector has ample room for valuation uplift. On the fundamental side, domestic large-scale energy storage continues to enjoy high prosperity under the support of capacity electricity price policies. From January to March this year, the bidding volume reached 164GWh, a year-on-year increase of 130%, and the production scheduling in the supply chain is nearing full capacity, with a month-on-month increase in orders in April.

The energy storage battery ETF E Fund (159566, feeder fund A/C: 021033/021034) tracks the CNI New Energy Battery Index, focusing on the core segments of energy storage batteries, with about 30% of its weight involving related sectors such as liquid cooling, high-voltage direct current, and solid-state transformers, which directly benefit from the AI narrative.
