Moody’s Trading Volume Surges 52% to $430M Secures Mid-Tier Liquidity Ranking

On October 1, 2025, Moody’s Corporation (MCO) reported a trading volume of $430 million, marking a 52.18% increase from the previous day’s activity. The stock closed with a 0.70% gain, securing a mid-tier position in market liquidity rankings.

Recent developments highlight Moody’s exposure to regulatory scrutiny and market sentiment shifts. Analysts noted that evolving credit rating framework adjustments by global regulators could influence demand for the firm’s services. Additionally, macroeconomic indicators suggesting a potential slowdown in corporate debt issuance were cited as factors affecting investor confidence in the sector.

To run this back-test accurately, clarification is required on three key parameters: the stock universe scope, weighting and rebalancing methodology, and benchmark selection. Details include whether to limit the universe to S&P 500 constituents, whether to apply equal weights with daily rebalancing, and whether to account for transaction costs or slippage. A designated benchmark, such as SPY, would also be necessary for performance comparison. With these parameters defined, the back-test can proceed from January 3, 2022, to the present date.
