Ronald Ratcliffe emphasizes the growing need for data-driven decision-making as markets face renewed volatility and higher interest rates.

With liquidity under pressure and wider bid-ask spreads becoming a concern, firms must diversify not just across markets—public and private—but also across asset classes and investment factors. This layered diversification helps maintain balance amid policy uncertainty and shifting economic signals.

By drawing on historical stress events like Brexit, the taper tantrum, and COVID, strategists can prepare for future shocks with greater confidence.
