Wall Street Bull Sees Buying Opportunity as Global Markets Slip Into a Jittery Summer Selloff

Market analysis

A jittery start to the summer has turned a once red-hot global equity backdrop spotty, with fresh geopolitical and sector-specific worries pushing markets lower. Renewed U.S.-Iran tensions and weakening visibility for artificialintelligence winners have dented sentiment, sending U.S. futures lower and prompting losses across the tech and semiconductor complex.

Koreas Kospi fell into bearmarket territory this week after renewed weakness at Samsung Electronics. Samsungs stock slid again on Wednesday following a 7% retreat on Tuesday and the knockon effect rippled through chipheavy indexes and funds. SK Hynix, another major Korean memory chip maker that plans a U.S. listing, also drew attention, and the Philadelphia Semiconductor Index (SOX) has been under pressure as investors reassess demand expectations for memory and logic chips.

The iShares Semiconductor ETF (SOXX) has suffered one of the sharper declines: the ETF is down nearly 14% so far this month, as investors digest disappointing company results and fading AI visibility that once underpinned huge gains in the sector.

Tom Lee, head of research at Fundstrat, argued in the firms call of the day that the selloff creates a buying window. Lee said Fundstrat is nearterm constructive and is buying the dip. He acknowledged investors face a sizable wall of worry from Samsungs results to reports that Amazon may not issue more debt after a recent sale but highlighted a number of reasons to be optimistic for the rest of the year.

Lee pointed to an improving Institute for Supply Management (ISM) index, which historically precedes accelerating earningspershare growth; potential upside to 2027 earnings estimates; and lower oil prices, which he said could eventually open the door to Federal Reserve rate cuts. He also noted that many largecap growth managers underperformed earlier this year, creating potential forced buying from fund managers who need to cover lagging performance: Fundstrats data shows 76% of largecap growth managers are underperforming their benchmarks by at least 10 basis points, and only 23% are outperforming by 10 basis points or more the smallest share since 2022.

Lee singled out Samsung as an example of a stock that has bounced before after heavy losses and suggested investors shouldnt be scared off, even if the nearterm technical picture is weak.

Market movers and indicators

U.S. stock futures were weaker amid the geopolitical tension, with S&P 500 futures (ES00) down about 0.55% and Nasdaq futures (NQ00) off roughly 0.74% as oil prices climbed. Brent and WTI rose on reports of military actions and disruptions, stoking safehaven and riskoff flows. The 10year Treasury yield climbed to the mid4% area, trading around 4.56%4.58% in intraday quotes, putting additional pressure on equity valuations.

In commodity and macro moves, crude oil jumped futures rose more than 5% intraday and heightened energy prices contributed to market volatility. Gold has been mixed, and Bitcoin was trading lower amid the riskoff move.

Market internals highlighted the stress in semiconductors and memory: names such as Micron (MU), Advanced Micro Devices (AMD), Intel (INTC) and Taiwan Semiconductor Manufacturing (TSM) were among the most searched and heavily traded, with significant intraday moves. Nvidia (NVDA), by contrast, remained an active and closely watched name given its central role in the AI trade.

Apple (AAPL) also attracted attention after reports it had begun testing memory chips from Chinas ChangXin Memory Technologies, a sign of ongoing supplier diversification in response to cost pressures and geopolitical risk.

Bank of Americasourced deposit data added another layer to the macro picture: it pointed to a stronger than reported job market, with unemployment payments into BofA customer accounts softening in June. Investors will also parse upcoming Fed minutes (the June meeting) and a $39 billion 10year note auction for clues about future policy and demand for duration.

What this means for investors

The confluence of geopolitics, higher rates and renewed doubts about the AI growth narrative has produced a classic sell first, ask questions later market environment. That has widened intramarket dispersion: many largecap growth managers have lagged, while pockets of the market have seen steep, shortlived drawdowns.

Fundstrats Tom Lee argues the present weakness represents a buying opportunity particularly in semiconductors and in battered megacaps that have seen profit taking rather than a fundamental breakdown. His thesis leans on cyclical signs (ISM improvement), potential earnings upside into 2027, and the mechanical need for fund managers to rebalance.

But investors should pair any dipbuying approach with risk management: the macro backdrop is fluid, with geopolitical shocks, oil price moves and sticky rates able to reignite volatility. For those looking to follow a buythedip play, prioritize positions with clearer earnings durability and consider staged entries or diversification across both semiconductors and higherquality large caps.

Ultimately, the markets next direction will hinge on incoming economic data, Fed communications, progress in Middle East tensions, and how quickly AI revenue forecasts realign with reality. For now, some Wall Street strategists view the pullback as an opportunity; others regard it as a reminder that markets can stay nervous for longer than investors expect.
