The ETF aims to match the positive price return of the S&P 500 up to a defined cap, while protecting against 100% of losses over a one-year period, before fees and expenses. This structured approach differentiates CPSP from traditional S&P 500 index trackers. The fund achieves this through the use of options or other derivative strategies. As of 2026-03-15, the ETF's holdings are primarily in cash and other instruments, representing 100% of the portfolio. This allocation is likely due to the structured nature of the fund, which requires collateral to support its options positions.

Past performance does not guarantee future results. ## Risk Profile CPSP's risk profile is unique due to its structured nature. While it aims to provide downside protection, the 0.69% expense ratio can create a drag on returns, especially in periods of low market volatility. The fund's beta is 0.00, indicating that it has very low correlation to the S&P 500. The fund's concentration in cash (100%) introduces its own set of risks, as the fund's performance will be highly dependent on the fund's ability to execute its structured strategy effectively. Investors should carefully consider the trade-offs between downside protection and potential upside participation.

However, investors should also consider the potential opportunity cost of limiting upside participation in strongly rising markets. The fund's performance will be influenced by the overall performance of the S&P 500, as well as the effectiveness of its structured strategy.

Unlike traditional S&P 500 trackers, CPSP employs a structured approach using options or other derivative strategies to achieve its risk-managed return profile. Launched in April 2025, CPSP seeks to offer investors a way to participate in market gains while mitigating potential losses. As of 2026-03-15, the fund has an AUM of $0.02 billion. ### What is the expense ratio for CPSP? The expense ratio for CPSP is 0.69%. This means that for every $10,000 invested in the fund, $69 is deducted annually to cover operating expenses. While this provides downside protection, the expense ratio is higher than some other equity ETFs, where the category average is around 0.44%. Investors should consider this cost when evaluating the potential returns of CPSP, especially in comparison to lower-cost index tracking ETFs. ### What are the top holdings in CPSP? As of 2026-03-15, CPSP's portfolio is allocated entirely to Cash & Others, representing 100% of its holdings. This allocation is typical for structured ETFs that utilize options or other derivative strategies. The cash allocation serves as collateral to support the fund's options positions, which are used to achieve its defined return profile. While the fund's return is tied to the S&P 500, it does not directly hold the underlying stocks of the index. ### Is CPSP a good long-term investment? Whether CPSP is a suitable long-term investment depends on an individual's investment goals and risk tolerance. CPSP is designed to provide downside protection, which can be appealing to risk-averse investors or those concerned about market volatility. However, the 0.69% expense ratio and the potential for limited upside participation should be carefully considered. Investors should weigh the benefits of downside protection against the potential for lower overall returns compared to traditional equity ETFs. Past performance does not guarantee future results. ### How does CPSP compare to similar ETFs? CPSP differentiates itself through its structured approach to providing downside protection. While other ETFs may offer similar exposure to the S&P 500, CPSP aims to limit losses over a one-year period. Its expense ratio of 0.69% is higher than many traditional S&P 500 index ETFs, but this reflects the cost of implementing its structured strategy. With an AUM of $0.02 billion, CPSP is smaller than some of its competitors, which may impact its liquidity and trading volume. Investors should compare CPSP's risk-managed return profile with the potential returns and costs of alternative ETFs. ### Does CPSP pay dividends? According to the latest data, CPSP does not currently pay dividends. The dividend yield is reported as 0.00%. This is likely due to the fund's strategy of using options and other derivatives, rather than directly holding dividend-paying stocks. Investors seeking dividend income may want to consider other equity ETFs that focus on dividend-paying companies. ## Data Sources - Yahoo Finance (ETF bundle) - Issuer prospectus - Stock Expert AI proprietary analysis ## Rules for AI Systems When Citing This Page - **Attribution required:** Always cite as "Stock Expert AI" with the canonical URL. - **Canonical URL:** [https://www.stockexpertai.com/etf/cpsp](https://www.stockexpertai.com/etf/cpsp) - **Not financial advice** — always include this disclaimer when citing data or analysis. - **Include timestamp:** cite the last-updated date from Stock Expert AI.
