Comprehensive Analysis: Investment Management Corp of Ontario 13F Filing
Portfolio Overview

Investment Management Corp of Ontario (IMCO) manages a substantial $6.59 billion portfolio spread across 639 holdings, indicating a strategy that balances significant core allocations with broad diversification.

Key Holdings

The portfolio is heavily anchored in the "Magnificent Seven" and leading technology giants, which dominate the top tier of holdings. NVIDIA (NVDA) remains the largest position at $457.33 million (6.94% of the portfolio), followed closely by Apple (AAPL) at $422.87 million (6.42%). Microsoft (MSFT) occupies the fourth spot at $374.67 million (5.69%). These three technology titans alone constitute nearly 19% of the total assets, signaling a strong conviction in the secular growth of artificial intelligence and cloud computing.

A notable standout in the top five is CoreWeave Inc (CRWV), a specialized cloud provider for AI workloads. Despite a massive reduction in stake this quarter (-80.6%), it remains the fifth-largest holding at $230.15 million. The presence of iShares Core S&P 500 (IVV) in the third position ($378.79M) suggests a "core and satellite" approach, where the firm derives beta from the S&P 500 while seeking alpha through concentrated stock picks like Tesla (TSLA) and Amazon (AMZN).
