COSW.PA ETFs replicate the performance of the MSCI World SRI index. Underlying Index Performance: The price largely mirrors the MSCI World SRI index. Upward or downward movements in the index constituents drive the ETF's price.

Supply and Demand: Increased demand raises the price, while higher supply lowers it. Trading volumes reflect this.

Management Fees: While indirectly, fees affect the ETF's net asset value and thus its attractiveness to investors. Higher fees can make it less appealing.

Currency Fluctuations: As the ETF invests globally, currency movements between the Euro and other currencies of constituent companies can impact the ETF's price.

Interest Rates: Changes in global interest rates, especially those of major economies represented in the index, can influence investor sentiment and thus the ETF's price.

Market Sentiment: Overall global economic and political sentiment affects investor appetite for equities, influencing demand for the ETF.

Tracking Error: The ETF aims to replicate the index's performance, but imperfections in replication can create a tracking error, affecting price.

Dividend Payments: Dividends received from underlying companies are distributed to ETF holders, affecting the ETF's attractiveness and thus the price.

Constituent Stock Performance: The performance of large-cap companies within the MSCI World SRI Index significantly affect COSW.PA, especially companies with high weights within the index.

SRI Focus: The socially responsible investing (SRI) criteria of the MSCI World SRI Index influence the constituent stocks. Changes in investor demand for SRI investments will also change the ETF price.
