US stocks ended Monday's session in positive territory following the release of an S-1 prospectus by Anthropic earlier in the day. The artificial intelligence developer is aiming to list on the Nasdaq in mid-November under the ticker symbol ANT. Sam Stovall, chief investment strategist at CFRA Research, discussed the potential impact of this event on investor sentiment during an interview with Brooke DiPalma.

Stovall suggested that the market's reaction reflects a return of optimism to the tech trade after a period of profit-taking. He noted that technology stocks had performed well previously, leading investors to secure gains. Beyond individual stock performance, Stovall pointed to favorable seasonal patterns that may support continued market strength. He observed that October is historically the best month in midterm election years and that the market is entering the three strongest quarters of the 16-quarter presidential cycle. Additionally, he stated that markets have never declined from October 31 of midterm election years through the following 12 months. Stovall argued that these factors contribute to a reluctance among investors to miss out on potential gains.

The conversation also addressed the competitive landscape, specifically regarding Anthropic's cited competitors Google and OpenAI. Stovall expressed the view that OpenAI may face greater challenges in 2027. He attributed this potential difficulty to the significant capital required for expansion and borrowing. While Stovall stated he does not follow individual stocks closely, he relayed information shared by a colleague named Angelo, indicating optimism regarding Anthropic but concerns about OpenAI's planned public offering next year.

Stovall addressed the role of emotion in investment decisions, referencing a note that warns against letting emotions become a portfolio's worst enemy. He argued that fear serves as a stronger motivator than greed for many investors. To illustrate this point, he cited data showing that days with market moves of 1% or more occur in 45% of bear markets but only 15% of bull markets. Stovall linked this disparity to adrenaline enhancing memory retention, noting that financial media often amplifies negative narratives during downturns. He advised against allowing fear to prompt exits from the stock market, highlighting historical recovery times. According to Stovall, it has taken an average of only four months for the market to return to breakeven following declines of up to 20%.
