Fundamentally, 516100.SHG's price mirrors its Net Asset Value (NAV).

Underlying Stock Performance: The ETF tracks the SSE STAR 50 Index, thus the performance of the constituent stocks directly influences its value.

Market Sentiment: Broad market optimism or pessimism towards Chinese technology stocks and the STAR market can impact investor demand and thus the ETF's price.

Supply and Demand: Higher demand for the ETF pushes its price up, while increased selling pressure can lower it.

Index Rebalancing: Periodic adjustments to the SSE STAR 50 Index composition may cause temporary price fluctuations as the ETF buys and sells stocks to match the updated index.

Fund Management Fees: While not directly impacting the intraday price, higher expense ratios can erode returns over time, affecting long-term valuation.

Arbitrage Activity: Market makers and arbitrageurs help maintain price alignment with the NAV by exploiting discrepancies between the ETF's price and the underlying stock values.

Regulatory Changes: New regulations impacting the STAR market or the technology sector can influence investor sentiment and ETF price.
