Defiance Memory & Photonics ETF (PRAM)

The Defiance Memory & Photonics ETF is a thematic exchange-traded fund sponsored by Defiance ETFs, an issuer known for funds built around emerging technology themes and leveraged single-stock products.

The fund focuses on two segments of the semiconductor and hardware supply chain that are central to artificial intelligence and data center buildouts: memory, including DRAM, high-bandwidth memory and storage chips, and photonics, which covers optical components, lasers and networking hardware used to move data at high speed.

It trades on Cboe BZX under the ticker PRAM and holds equities of companies whose businesses are tied to these technologies, offering targeted exposure to a narrow slice of the technology sector rather than broad tech.
