Major U.S. indices posted modest gains in August, with the S&P 500 up 2.62%, the Nasdaq gaining 3.93%, and the Dow advancing 1.34%—its fifth consecutive month of positive returns. The AI strategy's latest monthly selection includes companies such as Ramaco Resources, Salesforce, Peabody Energy, Mativ Holdings, and Gartner, which delivered respective August gains of 55.29%, 39.95%, 39.72%, 37.30%, and 31.18%.
Longer-term performance highlights include Delek US Energy at +97.46%, Haemonetics Corporation at +89.88%, Everforth at +84.62%, Consensus Cloud Solutions at +79.07%, and Nucor at +56.79% since initial selection. Haemonetics reported first-quarter 2027 revenue of $339.4 million and earnings per share of $1.14, exceeding expectations, while raising its full-year revenue growth guidance to a range of 5% to 8%. The company's gross margin stands at 58.8% and operating margin at 19.4%, with EBITDA up 23.6% year-over-year. Analysts at Citi have assigned a $90 price target and a Buy rating, while the consensus fair value target is $78.
A historical case study cited by the strategy involved Ameresco, which the models added at $15.87 in August 2025. The stock surged 136.55% to $37.54 within two months on the back of a $240 million hydroelectric contract in Alaska, before being rotated out at that level. The company later declined 36.39% to around $24, reflecting execution risks associated with project delays and supplier vulnerabilities.
