The vulnerability of mega-cap indices such as the S&P 500 and Nasdaq came into focus during the AI-led technology sell-off, according to HSBC Asset Management. Its report makes the case that equal-weighted benchmarks and sectors that have lagged could gain whether AI falters or continues to advance, with spillover effects and a broader spread of capital expenditure supporting Industrials and Financials. Portfolios diversified globally across sectors and market capitalisations are viewed as well placed.
"The recent AI-induced tech sell-off was a sharp reminder that relentless outperformance breeds fragility."

"Since 2011, the cap-weighted S&P 500 has trounced its equal-weighted cousin by nearly 225%, with just ten stocks commanding close to 40% of the index."
"Despite a modest de-rating this year, mega-cap tech remains hypersensitive to shifts in AI sentiment."
"Even if the tech story holds, AI spillovers—alongside broadening capex—should lift left-behind sectors and smaller-cap names across Industrials and Financials."
"The most compelling opportunities now lie beyond the mega-caps—leaving globally diversified portfolios across sectors, regions, and market caps well positioned for the coming years."
