I am not a financial advisor and please do your own research, as all investment contain certain amount of risk. Deciding whether to cut losses on a declining stock is a complex decision that depends on various factors, including your investment goals, risk tolerance, and the specific circumstances of the company in question. Here are a few things I will consider as investment is a long term commitment;

Evaluate the fundamentals: A declining stock over multiple quarters could indicate underlying issues with the company's fundamentals. Review the financial statements, earnings reports, and any relevant news or industry trends to assess the health of the business. Look for signs of declining revenue, increasing debt, or other red flags that may impact the stock's future prospects.

Diversification and risk management: Assess your overall investment portfolio. If the declining stock represents a significant portion of your holdings, it may be worth considering diversifying your investments to spread risk. Diversification can help mitigate losses and protect your portfolio against the volatility of individual stocks.

Seek professional advice: Consulting with a qualified financial advisor or investment professional can provide personalized guidance based on your specific situation. They can help analyze the stock's performance, evaluate the fundamentals, and provide recommendations tailored to your investment goals and risk tolerance.

Long-term perspective: Consider your investment horizon. If you are a long-term investor with confidence in the company's fundamentals, you may choose to hold onto the stock and wait for a potential turnaround. However, if you have a shorter investment horizon or the company's prospects appear uncertain, cutting your losses may be a more prudent approach.

Ultimately, the decision to cut losses on a declining stock should be based on a comprehensive analysis of the company's fundamentals, your individual financial situation, and your investment goals. It's essential to make informed decisions and consider seeking professional advice when necessary.
