Dividends: SCD primarily invests in dividend-paying stocks, thus dividend payouts significantly impact its price. Higher dividend yields typically lead to increased demand and a higher price, and vice versa.

Interest Rates: Rising interest rates can make bonds and other fixed-income investments more attractive, potentially decreasing the appeal of dividend stocks and lowering the price of SCD.

Market Sentiment: Overall market optimism or pessimism can influence SCD's price. Positive market sentiment often drives investments into equity ETFs like SCD, while negative sentiment can trigger sell-offs.

Underlying Stock Performance: SCD's price is directly affected by the performance of the underlying dividend-paying stocks it holds. If these companies perform poorly, SCD's price will likely decrease.

ETF Supply and Demand: The basic economic principle of supply and demand applies. Higher demand for SCD relative to its supply will push the price up, while increased supply with lower demand will push it down.

Fund Management Fees: While not a direct driver of price fluctuations, higher expense ratios relative to similar ETFs could make SCD less attractive, indirectly impacting demand and potentially its price.
