I’m Imran Siddiqui, a portfolio manager with three decades in investing. I’ve worked at JPMorgan Chase, Nomura, Merrill Lynch and Lion Capital, and spent twelve years running the international portfolio of Al-Jomaih Holding in Riyadh. Since 2015, from London, I’ve run Mosaic Capital Management on one simple idea: buy world-class businesses, don’t overpay, and let compounding work its magic.

Reuters has quoted me on the Federal Reserve and the banking system, my research has been referenced by Barron’s, and more than ten thousand people follow my macro commentary on X. This page is the quickest way into how I think.
