Underlying Bond Market: IHHY.AU tracks an index of high-yield corporate bonds. Bond price fluctuations directly impact the ETF's value.

Interest Rate Changes: Rising interest rates generally decrease bond values, negatively affecting IHHY.AU's price. Falling rates have the opposite effect.

Credit Spreads: Widening credit spreads, reflecting increased risk aversion, lower high-yield bond prices and IHHY.AU's value. Tightening spreads increase values.

Issuer Creditworthiness: Downgrades or defaults by companies within IHHY.AU's portfolio can lower the ETF's price. Upgrades can improve it.

Supply and Demand: ETF trading activity affects its price. High demand relative to supply can raise the price and vice versa.

Market Sentiment: Overall investor attitudes toward risk can influence high-yield bond investments and the ETF's performance.

Economic Conditions: Economic growth typically supports high-yield bond performance, while recessions often lead to declines in value.

Currency Fluctuations: Exchange rate changes between the Australian dollar and currencies of bonds held in the index may impact IHHY.AU's returns.
