VelocityShares Daily 2x Gold Miners ETF (DGP.US) price is influenced by several factors: Underlying Index Performance: DGP aims to deliver twice the daily performance of the NYSE Arca Gold Miners Index. Therefore, movements in this index significantly impact DGP's price.

Gold Mining Stocks: The performance of companies within the NYSE Arca Gold Miners Index, which are primarily gold mining businesses, affects DGP's price.

Leverage: As a 2x leveraged ETF, DGP's price is more volatile and sensitive to market fluctuations than non-leveraged ETFs.

Expense Ratio and Management Fees: These costs associated with managing the ETF reduce returns and affect the overall price.

Trading Volume and Liquidity: Higher trading volume and liquidity generally lead to tighter bid-ask spreads, potentially influencing the ease and cost of trading DGP.

Market Sentiment: Overall investor sentiment toward gold, gold mining companies, and the broader market can impact demand and, consequently, the ETF's price.

Rebalancing: Due to its leveraged nature, DGP requires daily rebalancing, which can impact its performance, especially in volatile markets, and therefore, affect its price.

Interest Rates: Changes in interest rates can affect the profitability of gold mining companies and investor sentiment towards gold as an investment, influencing DGP.

Currency Fluctuations: As the NYSE Arca Gold Miners Index comprises global companies, currency exchange rates can affect the performance of these companies, which can reflect on the DGP price.
