AMD stock sinks again despite bullish calls: what is spooking investors?

Advanced Micro Devices stock (NASDAQ: AMD) was heading for a second straight decline on Thursday despite bullish Wall Street research.

AMD fell about 3.2% to $513 in premarket trading after dropping 3.5% on Wednesday, putting the stock on course for a two-session fall of about 6%.

The weakness reflected a wider retreat from semiconductor stocks and concern that AMD’s elevated valuation leaves little room for delays in its ambitious AI roadmap.

A broader chip sell-off is dragging AMD stock lower

The Philadelphia Semiconductor Index fell 2.6% on Wednesday and ended about 16.5% below its June 22 high.

The Roundhill Memory ETF dropped roughly 7%, extending its decline from the recent peak to around 30%.

Those moves suggest investors are reducing exposure across the AI-hardware trade rather than responding only to AMD.

TSMC’s decision to raise capital spending after record earnings also revived questions about whether the industry is building capacity faster than customers can eventually monetise it.

Semiconductor shares delivered enormous gains in 2026 as chip shortages, rising prices and artificial-intelligence investment drove earnings forecasts higher.

That success has made the group vulnerable whenever investors question how long that growth can continue.

As per market data, the semiconductor index remained sharply higher for the year even after its July correction, while short interest and exchange-traded fund outflows had risen.

Alexander Lis, chief investment officer at SD Ventures, cautioned that target increases may partly reflect share-price momentum rather than guarantee future returns.

Wall Street is becoming more bullish

Rosenblatt Securities analyst Kevin Cassidy raised his AMD target to $665 from $490 and retained a Buy rating.

“We recommend owning AMD shares into the earnings report,” Cassidy said, according to TipRanks, citing EPYC server strength and AMD’s advantage following delays to Intel’s Diamond Rapids product.

UBS analyst Timothy Arcuri lifted his target to $700 from $670 and kept a Buy rating.

In a note reported, Arcuri said AMD’s July 22-23 AI event should highlight durable CPU and GPU roadmaps, possible partnerships and a broader data-centre market, while supply-chain checks remained supportive.

KeyBanc analyst John Vinh made the most aggressive call, raising his target to $725 from $530.

Vinh expects AMD’s AI GPU revenue to rise from $1.7 billion (approx. ₹157.9 billion) in 2026 to $4.9 billion (approx. ₹455.8 billion) in 2027 as additional server-processor capacity and the MI455 and Helios ramps support growth.

The real fear may be that perfection is priced in

William Blair analyst Sebastien Naji provides the clearest explanation for the sell-off.

He initiated coverage at Market Perform, warning that AMD’s rally had left the shares “priced at a premium to peers with little room for error.”

Naji estimated AMD was trading at 33 times 2027 earnings.

He also questioned how long server-CPU share gains can continue as Arm-based processors, Qualcomm, Nvidia and a recovering Intel increase competition.

In accelerators, AMD must still prove it can take durable share from Nvidia while hyperscalers develop their own chips.

Performance remains strong as first-quarter revenue rose 38% to $1 billion (approx. ₹96.8 billion), while Data Center revenue jumped 57% to $5.8 billion (approx. ₹545.1 billion).

AMD guided for second-quarter revenue of approximately $1.1 billion (approx. ₹105.3 billion).

The concern is therefore not weak demand today, but how much success the valuation already assumes.
