Underlying Index Performance: OVB's price closely tracks the performance of its underlying index, the S&P SmallCap 600 Value Index. Positive index performance generally increases the ETF price, and vice versa.

Supply and Demand: Increased demand for OVB shares can drive up the price, while increased selling pressure can lower it. This is influenced by investor sentiment and market conditions.

Net Asset Value (NAV): The ETF's NAV, representing the collective value of its holdings per share, is a key determinant. OVB's market price tends to align with its NAV.

Expense Ratio: Although indirect, OVB's expense ratio affects its long-term returns. Higher expenses can slightly reduce the overall return compared to a similar, lower-cost ETF.

Interest Rates: Changes in interest rates can affect the valuation of companies within OVB's portfolio, influencing its price. Higher rates can pressure some value stocks.

Economic Conditions: Broad economic factors like GDP growth, inflation, and unemployment can impact the profitability and valuation of small-cap value companies held by the ETF.
