# Why Direxion Korea Bull 3X (KORU) fell 4.05% on September 28, 2026

Direxion Korea Bull 3X (KORU) fell 4.05% on September 28, 2026 — Korea tech leak fears hit semiconductors.

## What happened

The Direxion Korea Bull 3X leveraged ETF tracked a Korea Tech selloff as data revealed nearly 40% of South Korean industrial technology leaks involve semiconductors.

## Why it moved

The 3X leveraged structure magnified the sector's decline; semiconductor IP leak concerns dragged the Korea Tech basket lower, and KORU's daily rebalancing amplified that downside into a -4.1% move.

## Why it matters

Korea Tech has stalled over three months despite sporadic bounces from Samsung's display wins and SK Hynix US partnerships; the HBM supercycle euphoria has worn thin as AI-chip concentration risk and IP security…

## What would break the thesis

Leveraged ETFs reset daily; if Korea Tech stabilizes or rallies, KORU's rebalancing can work in reverse and amplify upside, but structural decay in a choppy market will erode the fund.
