# Why Roundhill Photonics ETF (LYTE) fell 11.15% on November 3, 2026

Roundhill Photonics ETF (LYTE) fell 11.15% on November 3, 2026 — Tech selloff, Marvell-Lumentum deal revolt weigh.

## What happened

The Roundhill Photonics ETF fell 11.1% in a broad tech selloff that hit AI optics and interconnect names. The shared driver flagged in coverage was shareholder backlash against the Marvell and Lumentum merger deal,…

## Why it moved

Photonics names trade on the same AI-interconnect demand and valuation sentiment, so a deal backlash involving Lumentum and Marvell reprices the whole optics basket.

## Why it matters

This sits in the AI Optics and Interconnect theme, where datacenter interconnect buildouts lifted optical names as AI clusters scaled.

## What would break the thesis

A revised or abandoned merger terms would ease the pressure on the optics group. Renewed datacenter interconnect orders or a broad tech rebound would show the selloff is fading.
