BlackRock shuns the trade Wall Street can’t quit

For three straight years, one trade has dominated the U.S. stock market above everything else. You know it, your financial advisor knows it, and every passive index fund you own is loaded with it. The mega-cap technology bet has been the single most crowded position on Wall Street.

BlackRock, the firm managing $14 trillion in global assets, just released its Q2 2026 equity market outlook. The message challenges a core assumption that has guided portfolio construction for years: that sticking with what has worked will keep working. The firm’s top equity strategists see a market recalibrating in real time.

The question is whether you are positioned for where the market is going or where it has already been.

The mega-cap momentum trade is starting to crack

The top 10 stocks in the S&P 500 now represent roughly 41% of the index, the highest concentration in more than 35 years, according to RBC Wealth Management and FactSet data. That share was roughly 19% in 2015, and the previous record of 27% came at the dot-com peak in 2000.

BlackRock’s outlook acknowledges that the “Magnificent 7” stocks continue to lead earnings growth in early 2026. The catch is that those same stocks are no longer leading market returns this year.

“It’s a decidedly complex but exciting market, and one we believe is deserving of dynamic, active management in equities,” BlackRock’s Global CIO of Fundamental Equities Carrie King wrote in the firm’s Q2 2026 equity outlook.

BlackRock says the AI trade now demands a sharper filter

The firm is not walking away from artificial intelligence as an investment theme. BlackRock calls AI an “unmatched” mega force igniting lasting shifts in the profitability outlook across global economies. The distinction the firm draws is between blind exposure to the theme and selective, research-driven positioning within it.

BlackRock Co-Head and Co-CIO of Systematic Active Equities Jeff Shen argues that the environment demands greater selectivity and adaptability. The era when owning the largest AI-linked stocks generated outsized returns is fading, BlackRock’s outlook notes.

You need to ask tougher questions about which companies convert AI spending into measurable earnings.

“We expect market broadening to come not in large swaths, but in a growing number of interesting pockets across sectors and industries,” BlackRock’s CIO for Fundamental Equities Carrie King told Advisor Analyst.

This recalibration has created greater dispersion among technology stocks, and the gap between AI winners and laggards is widening significantly. A broad tech ETF may no longer deliver the concentrated upside it once did, because gains are becoming more selective.

The opportunity now favors companies that can demonstrate their AI capital expenditure is translating into sustainable revenue growth.

BlackRock says the AI trade is shifting from broad bets to selective positioning, as returns now depend on which companies can turn AI spending into real earnings growth.

The case for looking beyond U.S. borders is getting louder

BlackRock’s Q2 outlook argues that growth opportunities are no longer limited to U.S. mega-cap stocks. Helen Jewell, the firm’s International CIO for Fundamental Equities, sees surprise pockets of value for investors willing to hunt globally. The firm highlights Europe, the United Kingdom, Japan, and parts of Latin America.

The S&P 500 trades at a forward price-to-earnings ratio of roughly 22 times, matching the 2021 peak multiple, according to Goldman Sachs Research. That valuation premium makes domestic bargains scarce and raises downside risk if earnings miss expectations.

This doesn’t mean you should abandon U.S. stocks entirely or sell your index funds tomorrow morning. The message from BlackRock is about balance and about recognizing your portfolio may be far more concentrated than you realize.

If your retirement account holds primarily S&P 500 index exposure, about 40 cents of every dollar is tied to a handful of tech companies.The practical step is to review your allocations and determine whether you hold meaningful international exposure at all.

Many investors keep 80% or more of their equity allocation in U.S. stocks, and that served them well during a decade of domestic outperformance. BlackRock’s argument is that the conditions supporting that extreme home bias are shifting.

European defense and UK banks top BlackRock’s international picks

The firm’s global tour of value starts with European defense stocks. EU member states collectively spent roughly €343 billion on defense in 2024, up from €240 billion in 2022, with estimates reaching €381 billion for 2025, according to the European Defence Agency.

BlackRock sees continued value in the sector despite strong recent gains, as geopolitical tensions keep defense spending firmly in focus.

The firm also highlights European and UK banks, which have benefited from higher interest-rate margins and improved balance-sheet quality. BlackRock singles out U.K. banks and small caps as particularly interesting corners that remain undervalued relative to their earnings power.

In emerging markets, BlackRock points to Latin America, particularly Brazil. The Brazilian economy is showing signs of improvement, and BlackRock believes an active approach to stock selection can uncover opportunities that broad emerging market ETFs often miss.

Japan’s new pro-growth government reinforces the equity case

Japanese equities outperformed global markets over the past five years, and BlackRock expects that trend to persist. The February 2026 elections installed a pro-growth, pro-investment government that reinforces existing tailwinds for Japanese stocks, according to BlackRock’s outlook.

BlackRock’s Japan team highlights three structural drivers: supportive monetary policy from the Bank of Japan, corporate transformation efforts that have improved return on equity, and a political environment now aligned with investment-friendly policies.

Japanese companies have made meaningful progress in governance reforms, unwinding cross-shareholdings, and returning more capital to shareholders over recent years.

The opportunity in Japan, BlackRock argues, lies in individual stock selection that scans across sectors and company sizes. The firm’s strategists see companies poised to benefit from the wave of transformation, particularly those with improving profitability metrics and strong cash generation.

How to apply BlackRock’s outlook to your own portfolio

BlackRock’s central message is not that mega-cap stocks are doomed or that you should liquidate U.S. holdings overnight. The firm still believes AI is the most powerful investment theme in the market today, and the earnings fundamentals of the largest technology companies remain strong.

Key takeaways from BlackRock’s Q2 2026 equity outlookThe Magnificent 7 still lead earnings growth, but they are no longer leading market returns in 2026, which signals a rotation.AI investing now requires sharper selectivity, and broad technology exposure alone may not capture the strongest opportunities ahead.European defense stocks, U.K. banks, Japanese equities, and Brazilian stocks rank among BlackRock’s top global value picks.The S&P 500’s top 10 stocks hold roughly 41% of the index, creating concentration risk that passive investors may underestimate.BlackRock favors active stock selection, over passive index exposure and emphasizes a broader global search for growth.Concentration risk is real, but diversification is not a guarantee

History shows that extreme market concentration has typically been followed by underperformance from the most heavily weighted stocks.

After the dot-com bubble peaked in 2000, with the top 10 at roughly 27%, those companies underperformed the broader market for years, according to Osborne Partners research. Today’s concentration at 41% is significantly higher.

Diversification does not guarantee profits or protect against losses in a declining market. International stocks carry their own risks, including currency fluctuations, political instability, and regulatory differences that can affect returns unpredictably.

The goal is not to chase the next hot region based on a single quarterly outlook from any firm. It is to ensure your portfolio reflects the broader opportunity set in global equity markets, rather than passively concentrating on a handful of companies that grew fastest over the past decade.

If you are unsure how to evaluate your concentration, a qualified financial advisor can help assess your specific situation.
