Fundamental Factors: Performance of underlying small-cap value stocks significantly influences DFAS.US. Broad economic conditions and interest rate changes also play a role.

Supply and Demand: ETF prices fluctuate based on buyer and seller activity. High demand generally increases the price, while increased selling pressure can lower it.

Market Sentiment: Overall investor optimism or pessimism towards small-cap value stocks can affect DFAS.US. Negative sentiment may lead to selling, while positive sentiment can drive buying.

Index Tracking: DFAS.US aims to mirror its benchmark index, so deviations from the index's performance can cause price discrepancies.

Expense Ratio: The ETF's operating costs, known as the expense ratio, can indirectly impact its price by reducing overall returns over time.

Liquidity: Higher trading volume and tighter bid-ask spreads indicate greater liquidity, which can contribute to more stable pricing.

ETF Structure: The creation and redemption mechanism of ETFs, allowing authorized participants to create or redeem shares, helps keep the ETF price aligned with its net asset value.
