A research firm is advising investors to focus on defensive stocks as a warning signal in the economy emerges. According to the firm, this signal suggests that it may be a good time to load up on defensive stocks. This recommendation comes as a result of their analysis of market trends and indicators. Defensive stocks are typically those of companies that are less sensitive to economic downturns, such as utilities, healthcare, and consumer staples. By investing in these types of stocks, investors may be able to protect their portfolios during times of market volatility. It is important for investors to carefully consider their investment strategies and consult with a financial advisor before making any decisions.
