Economic Growth: Strong economic growth often supports high-yield bond prices, leading to an increase in HYG.MX's price, as default risk decreases.

Market Sentiment: Positive market sentiment and risk appetite can drive investors towards riskier assets like high-yield bonds, increasing HYG.MX's price.

Inflation: Higher inflation can negatively impact HYG.MX's price, because it erodes the real value of fixed income payments.
