Semiconductor ETF inflows hit $4.5B as Fidelity warns of cycle peak

Investors poured $4.53 billion into the leveraged Direxion Daily Semiconductor Bull 3X ETF (SOXL) over the past month even as Fidelity Investments' Jurrien Timmer warns the sector's roughly 40-month earnings cycle is nearing a peak.

"I'm a little surprised to see the speculative flows into semiconductor ETFs be as sticky as they are," Timmer, Fidelity's director of global macro, said on X. "While the AUM of these ETFs is way down, the flows have not really reversed."

SOXL's inflows arrived as its assets under management fell $906.07 million on extreme price swings. The VanEck Semiconductor ETF (SMH) drew $1.04 billion while shedding $2.03 billion in AUM, and the iShares Semiconductor ETF (SOXX) added $1.53 billion while losing $4.60 billion, one-month fund flow data shows.

The gap between new cash and shrinking value shows traders aggressively buying the dip in a sector whose funds have returned as much as 238 percent year-to-date. A turn in the cycle would hit leveraged holders hardest, because SOXL's daily-reset structure amplifies losses as fast as gains.

Flows Stay Sticky as Values Shrink

Timmer, who tracks aggregate flows across U.S. and South Korean semiconductor markets, pointed to the historic disconnect between falling asset values and persistent speculative buying. The semiconductor industry historically runs on a roughly 40-month earnings cycle, he said, and the current trajectory suggests momentum may soon run out.

"While the earnings momentum remains strong, we are 'due' for a cycle peak relatively soon," Timmer warned. "Perhaps we are about to reach peak rate-of-change."

The pattern extends beyond leveraged products. SOXX, which holds 31 stocks across the production chain including memory maker Micron and equipment supplier Applied Materials, is up 79.26 percent year-to-date. SMH, the most concentrated broad fund with Nvidia at about 22 percent of the portfolio, has returned 60.97 percent. SOXL has surged 238.23 percent year-to-date but fell 26.06 percent over the past month as volatility spiked.

The buying reflects an AI-driven memory shortage that has given chipmakers unusual pricing power. High-bandwidth memory, the stacked DRAM that AI accelerators require, is sold out, and new fabrication capacity is not expected online until mid-2027. Samsung and SK Hynix together control about two-thirds of global DRAM production, concentrating supply in South Korea while TSMC anchors advanced logic in Taiwan.

What a Cycle Peak Means for Leveraged Holders

The stakes are highest for SOXL, which delivers three times the daily return of the semiconductor index. Its 1-year gain of 407.71 percent reflects a powerful uptrend, but the daily-reset leverage causes volatility decay over time, and the fund would fall fastest if the memory cycle turns. South Korea's financial regulator has already moved to cap retail exposure to leveraged ETFs after a batch of high-leverage products fueled a global chip selloff in June.

For investors, the divergence between flows and value cuts both ways. Sustained inflows support semiconductor stocks and the tech-heavy Nasdaq in the near term, but a confirmed cycle peak would trigger amplified losses in leveraged funds and could spill into the broader complex. Timmer's warning frames the trade as a timing question: how much longer earnings momentum can outrun the cycle's historical clock.
