Looking to boost your ISA in 2026? Consider these two top ETFs with unique approaches to investing. First, the iShares Automation & Robotics ETF (LSE: RBTX) offers exposure to 137 stocks in the robotics sector, including chipmaker giants like Nvidia and Advantest, a leader in semiconductor testing. While the ETF's performance may be impacted by potential 'AI bubble' bursts and trade tensions, its diverse holdings and strong performance since 2016 make it an attractive long-term investment. Next, the iShares MSCI Target UK Real Estate ETF (LSE: UKRE) invests in 28 UK REITs, property companies, and fixed-income securities. Despite recent share price slumps due to rising interest rates, this fund offers a 6.5% dividend yield and a defensive income stream from UK inflation-linked bonds. With interest rates expected to fall next year, high-quality REITs could see a boost in sentiment.
