PQUS · Exit · 1d

The observed weight change for CSGP in PQUS, transitioning from a consistent 0.0600% to a full removal on June 26, 2026, indicates a stepped exit consistent with the ETF’s periodic rebalancing, not daily adjustments. This decisive action by Pictet Asset Management’s AI ranking system comes as CoStar Group shares have experienced a substantial price decline, registering a 1-year return of -65.2% and currently sitting at the $28.64 low end of its 52-week range. Such a significant deterioration in market value, coupled with CSGP’s high PER of 499.41 and a low ROE of 0.3%, likely triggered a re-evaluation within the fund’s US large-cap universe. Even within an investment style emphasizing measured turnover, the AI’s model would deem a stock trading at 30% of its 52-week high, while maintaining such an elevated valuation multiple against minimal profitability, unsuitable for continued inclusion in the portfolio.

PQUS · Weight decrease · 2d

CSGP's PER of 541.89 and extremely low ROE of 0.3% likely presented a concerning valuation and profitability profile for PQUS, despite the 21.33% revenue growth. Operating with its AI ranking system over a US large-cap universe, Pictet Asset Management's ETF initiated a consecutive weight decrease for CSGP on May 28 and 29. This adjustment occurred as the stock traded near $32.30, close to its 52-week low, following a -19.3% return over the prior 30 days. The AI's systematic review, layered with sector-balance and concentration rules, appears to have driven the company's re-ranking downward. Consequently, the position decreased from 0.3600% to 0.2500%, reflecting a measured turnover adjustment in response to the significant price decline and weak profitability metrics.

PQUS · Weight increase · 2d

CSGP is currently trading at $34.01, substantially below its 52-week high of $96.83, reflecting a 55.2% decline over the past year and a 42.6% drop in the last 90 days, positioning the stock at approximately 35% of its peak. Against this significant price depreciation, Pictet Asset Management's AI ranking system for PQUS appears to have identified CSGP as a re-weighting candidate. The AI's evaluation likely prioritized the company's 21.33% revenue growth within its US large-cap universe, potentially considering the stock's current price relative to its growth prospects, even with a high PER of 562.64 and low ROE of 0.3%. The consecutive weight increases on May 20th and 21st, pushing the stock from 0.3600% to 0.3800% in PQUS, indicate a specific adjustment during one of the fund's periodic rebalances, aligning with its measured turnover style and concentration rules for its ~165 US large-cap holdings.

PQUS · Weight decrease · 2d

The AI ETF is likely decreasing its weight in CoStar Group due to the company's extremely high P/E ratio of 549.3 and very low ROE of 0.3%, indicating significant overvaluation and poor profitability despite strong revenue growth. For retail investors, this underscores the importance of scrutinizing profitability and efficiency metrics like ROE in addition to revenue growth, as high growth alone does not justify extreme valuations or guarantee financial health.
