Semiconductor investors faced a turbulent session on Wednesday as the VanEck Semiconductor ETF (SMH) slid 1.2% following the abrupt termination of merger discussions between Marvell Technology (MRVL) and Broadcom (AVGO). The breakdown in negotiations rippled across the chip sector, overshadowing a modest advance in the broader market.
By mid-morning trading, SMH had fallen 1.18% to $563.05, while the S&P 500 gained 0.37%, highlighting the divergence between chipmakers and the wider equity market. The iShares Semiconductor ETF (SOXX) suffered an even steeper decline of 2.22%, underscoring the breadth of the pullback.
Within SMH, Marvell shares surged 8.18%, contributing roughly 0.35 percentage points to the fund's performance. However, Broadcom dropped 5.69%, shaving off about 0.32 points. These two moves nearly canceled each other out, leaving the remainder of the portfolio to drive the fund's decline.
Other major chip names also felt the pressure. Advanced Micro Devices (AMD) fell 4.16%, Micron Technology (MU) declined 0.68%, and Nvidia (NVDA) slipped 0.15% after an initial advance. Taiwan Semiconductor Manufacturing (TSM) managed a slight gain of 0.07%, but it was not enough to offset the broad weakness.
The aborted deal had significant strategic implications. Google secured warrants to acquire up to $12.18 billion in Marvell stock, with most warrants vesting only if Marvell meets purchase milestones by fiscal 2033. This development poses a direct challenge to Broadcom's position in the custom AI chip market, a segment that has become a key battleground for semiconductor companies.
Tuesday's session had already set a negative tone, with SMH dropping 4.1% as Treasury yields climbed. Combined with Wednesday's losses, the two-day decline amounts to roughly 5.2%, pushing the fund more than 16% below its 52-week high of $671.83. Despite this pullback, SMH has still gained nearly 68% year-to-date as of early July, reflecting the sector's strong performance over the past year.
Analysts remain optimistic on individual names. Stifel's Ruben Roy reiterated a Buy on Nvidia with a $282 target, while Citi's Atif Malik maintained a Buy on Broadcom with a $500 price objective. Bank of America's Haas Liu and UBS's Timothy Arcuri also kept Buy ratings on Taiwan Semiconductor and Micron, respectively. However, these bullish stances are company-specific and do not necessarily signal strength for the entire ETF.
The broader market context adds another layer of concern. Despite softer bond yields, with the 30-year Treasury slipping to 5.209%, chip stocks failed to find support. Robert Pavlik of Dakota Wealth noted that "when interest rates creep up, those expectations are worth less," highlighting the sensitivity of growth-oriented tech stocks to rate movements.
Looking ahead, the sector's recovery will depend on several factors. Nvidia's earnings report on August 26 could be a major catalyst, while any reversal in yields or renewed AI demand could quickly change sentiment. The key metric to watch is market breadth—sustained gains require more than isolated deal-driven moves. If AMD, Micron, and equipment makers regain footing, SMH may rebound; otherwise, Marvell's surge may prove to be little more than a footnote.
