Nasdaq surges to 25,833 as mega-cap tech reasserts its grip on global markets

The numbers came in hard overnight. The Nasdaq Composite jumped 1.87 per cent to close at 25,833, while the broader S&P 500 added 1.71 per cent to reach 7,483. For anyone in Bendigo who glanced at their industry super fund balance this morning and felt a quiet relief, this is the rally responsible. The technology-heavy Nasdaq has now reasserted itself as the engine room of global equity returns, dragging everything from Australian retirement savings to local sharemarket sentiment with it.

The ASX 200 caught the tailwind, rising 0.92 per cent to 8,844, with the All Ordinaries not far behind at 9,048, up 0.94 per cent. The Australian dollar firmed to US69.43 cents, a gain of 0.68 per cent, reflecting a broader appetite for risk assets. When Wall Street puts on a session like that, Sydney and Melbourne tend to follow. Bendigo is no different: members of funds such as Australian Super, HESTA and Cbus hold significant allocations to global equities, and a meaningful portion of those allocations sits in US technology stocks, either directly or through index funds tracking the S&P 500 and the Nasdaq.

So what exactly is driving the mega-cap technology trade, and why does it keep reasserting itself? The answer starts with concentration. The five largest companies in the S&P 500, including Apple, Microsoft, Nvidia, Alphabet and Amazon, account for a share of the index's total market capitalisation that would have seemed implausible a decade ago. When those stocks move, the index moves. The Nasdaq, which skews even more heavily toward technology and growth names, amplifies that effect further. A strong session for semiconductor stocks or cloud computing names can shift the Nasdaq by a percentage point or more in a single day, as Thursday's session demonstrated.

Why the tech trade keeps pulling capital back in

The structural case for mega-cap technology is well-rehearsed but no less powerful for its familiarity. These companies generate extraordinary free cash flow, hold fortress balance sheets, and are positioning themselves at the centre of artificial intelligence infrastructure spending. Capital expenditure programmes announced by the major US cloud providers over the past 18 months have run into the hundreds of billions of dollars, a scale that crowds out smaller competitors and reinforces the incumbents' advantages. Markets have spent much of 2025 and early 2026 debating whether that spending will generate commensurate returns; sessions like Thursday suggest investors are, for now, voting yes.

There is a shadow on the picture, and it shows up in gold. Spot gold rose 4.10 per cent to US$4,187 an ounce, a move that does not sit comfortably beside a straightforward risk-on narrative. Gold at that level, and rising that sharply in a single session, suggests some investors are hedging against something: currency debasement, geopolitical disruption, or simply the possibility that the equity rally is running ahead of underlying economic conditions. WTI crude fell 2.78 per cent to US$68.78 a barrel, reflecting softer demand expectations that cut against the optimism priced into equities. Bitcoin added 6.79 per cent to reach US$62,536, which tends to track risk sentiment but also attracts its own speculative flows when volatility picks up.

For Bendigo readers with resources-linked wealth, the crude oil slide is worth watching. Energy stocks on the ASX, including Woodside and Santos, are sensitive to the WTI price, and sustained weakness in crude can weigh on dividend income and share prices in that sector. Western Australian gold producers are sitting in a very different position: with gold above US$4,000 an ounce, the economics of reopening idled mines and extending existing operations look compelling. The Katanning district in WA is among several communities eyeing exactly that opportunity.

The Melbourne property market, meanwhile, is heading in a direction that contrasts sharply with the exuberance on Wall Street. Investor retreat following the Victorian state budget has pushed auction clearance rates lower and cooled sentiment in what was already a tentative market. That divergence, strong financial assets, soft property, is a meaningful one for Bendigo households deciding how to allocate savings. Industry super funds with diversified global equity exposure have delivered returns that local property investors have not seen recently.

The Nasdaq rally is not guaranteed to hold. Technology stocks can reverse quickly when interest rate expectations shift or when earnings disappoint. But Thursday's session was a reminder that the mega-cap technology trade has proven resilient across multiple market cycles, and that Australian investors, through their superannuation funds, are more exposed to it, and more dependent on it, than many realise.
