Underlying Asset Performance: The primary driver is the performance of the underlying CSI New Energy Vehicle Index. Positive index returns typically raise the ETF price, while negative returns lower it.

Supply and Demand: Market forces play a role. High demand relative to supply can push the price above its net asset value (NAV), while excess supply can lead to trading at a discount.

NAV Movements: The Net Asset Value (NAV) calculation directly impacts the ETF's theoretical fair value. Changes in the values of the included new energy vehicle stocks affect NAV.

Investor Sentiment: Broad market sentiment towards the new energy vehicle sector influences investment flows and therefore ETF prices. Positive sentiment drives inflows, increasing price.

Expense Ratio & Management Fees: While not directly affecting daily price swings, the expense ratio and management fees impact long-term returns, potentially indirectly impacting attractiveness.

Index Tracking Efficiency: How closely the ETF tracks its underlying index affects its price. Imperfect tracking creates tracking error, potentially causing deviations from index performance.

Arbitrage Opportunities: Arbitrage activity helps keep the ETF price aligned with its NAV. Mispricings attract arbitrageurs who buy/sell to profit, thus affecting price discovery.
