U.S. stock indexes turned in a broadly positive week, with the S&P 500 rising 1.2%, the Dow Jones Industrial Average adding 0.9%, and the Nasdaq Composite climbing 0.6%, while the Russell 2000 slipped 0.9%. Several specialized exchange-traded fund sectors outpaced the major benchmark indexes, driven by political shifts, geopolitical tensions, and artificial intelligence infrastructure demand.

Brazilian equity funds jumped after right-wing Senator Flavio Bolsonaro won 47% of the first-round presidential vote, outpacing incumbent Luiz Inacio Lula da Silva's 45%. In shipping, tanker ETFs gained as attacks on commercial vessels in the Strait of Hormuz forced ships onto longer routes, reducing available global fleet capacity and raising marine insurance costs. Meanwhile, utility funds rallied following a 20-year nuclear power supply deal between Google and Constellation Energy (CEG), signaling strong ongoing power needs for AI data centers.

Cybersecurity and cloud computing funds also advanced as rising AI adoption boosted spending on digital defense and enterprise cloud infrastructure. Investors will monitor whether accelerating cloud revenue growth and upcoming corporate spending updates support valuations across these outperforming market segments, alongside the outcome of Brazil's runoff election on Oct. 25.
