Billionaire investor Kenneth C Griffin runs one of the most successful hedge funds in the world. As the founder and CEO of Citadel Advisors with a majority stake, Griffin has a net worth of £33.24 billion ($43 billion) and loves math, which is evident from his quantitative investing approach.

Since its inception in 1990, the hedge fund has generated net gains of over £57.21 billion ($74 billion) and is known for its open-mindedness to diverse asset classes.

While the hedge fund manager could be more vocal about his trades and strategies, his investing approach reveals patterns of high-frequency trades backed by complex algorithms.

In Q4, Griffin made significant changes to Citadel's portfolio, which has £83.62 billion ($108.16 billion) worth of assets under management.

The technology company offers human capital management (HCM) and employment administration outsourcing solutions. For the quarter-ended 31st December, the company recorded revenue growth across verticals, which management said was fueled by a strong 'demand backdrop,' solid new business bookings growth, and higher client funds interest revenue.

In 2024, the company's net revenue increased by 14% year-over-year amid robust macroeconomic environments and momentum in capital markets.

In Q4, the company posted a YoY drop in revenue to £11.75 billion ($15.2 billion) and widened its non-GAAP loss per share to £4.56 ($5.90). The aircraft manufacturer attributed the results to work stoppage, charges for some defence programmes, and workforce reductions.

For the full-year 2024, the company delivered 348 commercial airplanes and recorded 279 net orders.
