Underlying Asset Performance: GG3S tracks a specific index. The ETF's price closely mirrors the performance of the assets within that index. If the index goes up, the ETF price typically rises, and vice versa.

Supply and Demand: Like any traded asset, GG3S's price is influenced by supply and demand. High demand tends to push the price upward, while increased selling pressure can lead to price declines.

Market Sentiment: Overall investor confidence and risk appetite affect ETF prices. Positive market sentiment usually drives more investment into ETFs like GG3S, increasing their value. Negative sentiment can cause sell-offs.

Expense Ratio: While not directly impacting daily price fluctuations, the ETF's expense ratio (the annual fee charged to manage the fund) can affect its long-term performance relative to its underlying index.

Trading Volume and Liquidity: Higher trading volume typically leads to tighter bid-ask spreads, making it easier to buy and sell GG3S shares at a fair price. Low liquidity can result in wider spreads and greater price volatility.
