PQUS · Weight increase · 2d

BSX's revenue growth of 17.44% and return on equity of 14.87% present a case for its inclusion in Pictet Asset Management's US large-cap universe, aligning with the ETF's measured turnover style for companies with tangible financial performance. The AI ranking system within PQUS likely identified an opportunity as Boston Scientific's stock, priced at $44.03, had fallen to approximately 41% of its 52-week high, nearing its 52-week low after significant declines over the past year. This substantial depreciation, alongside the company's financial metrics, appears to have triggered the consecutive weight increase for BSX from 0.91% on July 16 to 1.03% by July 18. Such a move reflects the AI's re-evaluation of BSX as a potential value within its sector-balanced rules, capitalizing on the recent price depreciation for a large-cap company demonstrating sustained revenue expansion.

PQUS · Weight decrease · 2d

Boston Scientific Corporation currently trades at $44.77, a mere 41% of its 52-week high, after suffering 30-day and 90-day returns of -8.8% and -39.4% respectively, alongside a -58.0% one-year return. This sustained underperformance likely prompted Pictet Asset Management's AI ranking system, governing the PQUS ETF, to re-evaluate the stock despite its 17.44% revenue growth and 14.87% ROE. Operating within a periodic rebalancing schedule for its ~165 US large-cap portfolio, the fund's AI initiated a reduction in BSX's weight, leading to the observed consecutive decreases from 0.97% on July 10th to 0.95% by July 12th. These adjustments align with the ETF's measured turnover style and its embedded sector-balance and concentration rules, responding to BSX's substantial market price decline.

PQUS · Weight increase · 2d

Boston Scientific Corporation shares currently sit at $44.99, a full 42% below their 52-week high of $108.14, having experienced steep negative returns over the past year and placing the stock near its $42.68 52-week low. This dramatic price depreciation occurred even as the company reported a 17.44% revenue growth and a 14.87% return on equity, indicating underlying business strength despite market sentiment. PQUS, an AI-managed ETF employing an AI ranking system for US large caps with periodic rebalances and measured turnover, likely identified this divergence. The fund's AI appears to have considered BSX an accumulating opportunity at these depressed levels, leading to a consecutive increase in its weight from 0.91% to 0.97% between July 8th and July 10th.

PQUS · Weight decrease · 2d

With a PER of 18.81 and a 14.87% ROE, Boston Scientific Corporation exhibits financial characteristics that align with a US large-cap investment. However, the AI ranking system managing Pictet Asset Management's PQUS fund initiated a series of consecutive weight decreases for BSX, moving from 0.9700% on June 25th to 0.8700% by July 2nd. This measured portfolio adjustment by the AI system, which adheres to a measured turnover style, directly correlated with the stock trading near its 52-week low of $42.68, having experienced a -24.2% return over the prior 30 days. Despite a 17.44% revenue growth, the sustained price depreciation and the stock's position at 40% of its 52-week high evidently prompted the AI's re-evaluation and reduced allocation within the PQUS portfolio.

PQUS · Weight decrease · 2d

Boston Scientific Corporation's 17.44% revenue growth and 14.87% Return on Equity present a profile consistent with the US large-cap universe targeted by Pictet Asset Management's PQUS ETF. Despite these underlying metrics, the AI ranking system initiated a weight reduction for BSX from 0.9500% to 0.9300% on 2026-06-24, occurring as the stock was trading at $44.23, near its 52-week low following a -42.0% 90-day return. This action reflects the AI's re-evaluation within its sector-balance and concentration rules, indicating a diminished conviction that led to a net decrease in allocation from its prior stable level of 0.9500% down to 0.9400% by June 27th, indicative of a sustained re-positioning during the fund's periodic rebalancing.

Boston Scientific Corporation currently trades at $46.91, marking its 52-week low and representing only 43% of its high, following a -55.0% return over the past year and -17.0% in the last 30 days. This persistent downward price pressure likely influenced Pictet Asset Management's AI ranking system for its US large-cap universe during a recent periodic rebalance in PQUS. Despite BSX's 17.44% revenue growth and 14.87% ROE, the AI's re-evaluation, combined with the fund's sector-balance and concentration rules, prompted a consecutive weight decrease. This adjustment saw BSX's allocation in PQUS move from 1.0400% on June 12th to 0.9900% by June 14th, reflecting the AI's response to the stock's significant underperformance at its current valuation.

PQUS · Weight decrease · 4d

The AI ranking system employed by Pictet Asset Management for PQUS, which holds around 165 US large-cap stocks, evidently triggered the consecutive weight reduction for Boston Scientific. This pattern of decreases from late May suggests the fund’s periodic rebalance mechanism, as opposed to daily trading, adjusted the allocation based on recent stock performance. Boston Scientific's substantial 1-year return of -54.4% would have profoundly altered its standing within the AI's selection criteria, driving the methodical reduction in its portfolio presence. This move is consistent with PQUS's stated style of US large-cap investing with measured turnover, where underperforming assets are systematically re-evaluated.

AIVL · Weight increase · 2d

AIVL increased its holding in Boston Scientific, exhibiting a gradual consecutive weight increase from 0.2032% to 0.2093% between July 14th and 16th, precisely as the stock traded near the lower end of its 52-week range at $44.03. This calibrated adjustment aligns with WisdomTree’s AI strategy, which aims to identify genuine value within its US value-factor pool by analyzing fundamentals like margins and return on capital alongside valuation metrics. Despite the substantial 37.1% ninety-day decline in BSX’s price, the company reports a 17.44% revenue growth and a 14.87% ROE, figures the AI likely interpreted as supporting underlying strength rather than a value trap. Given BSX's current low price point relative to its historical high, the AI’s model probably scored the healthcare company favorably on its valuation metrics while recognizing its operational performance, leading to the incremental rise in allocation within AIVL’s ~100 US value stock portfolio.

AIVL · Weight increase · 2d

AIVL’s methodology, which employs AI to score names within a pre-filtered US value-factor pool and distinguish genuine value from value traps, appears to have identified Boston Scientific as a compelling opportunity amidst recent declines. The AI, evaluating fundamentals such as BSX's 14.87% ROE and 17.44% revenue growth, likely concluded that the company's underlying business health was not fully reflected in its depressed valuation. With BSX currently trading at just 42% of its 52-week high and experiencing a -55.4% one-year return, the system's focus on valuation metrics like P/E and P/B would naturally highlight the stock as a potential candidate for increased allocation within the portfolio of approximately 100 US value stocks. This assessment led to the observed consecutive weight increase from June 30th to July 2nd, indicating the AI's growing conviction in the stock as a genuine value play suitable for inclusion in the periodically rebalanced fund.

Boston Scientific Corporation currently trades at $44.23, hovering at 41% of its 52-week high and near the bottom of its $44.20 to $108.14 range, following a -55.7% decline over the past year. AIVL, which uses AI to distinguish genuine value from value traps within a US value-factor universe, systematically decreased its allocation to BSX, as shown by the recent shifts from 0.2206% to 0.2096%. Despite the substantial price drop, the AI’s continuous re-evaluation, based on fundamentals like margins and return on capital alongside valuation metrics such as P/E of 19.09 and P/B of 5.83, suggests it does not perceive sufficient underlying quality or future upside to warrant a higher weighting at this price level. This sustained reduction indicates that for AIVL’s AI, the stock's current price and metrics, including its 14.87% ROE and 17.44% revenue growth, align more with a value trap assessment rather than an undervalued asset requiring increased exposure.

AIVL · Weight decrease · 6d

The consecutive, daily decreases in Boston Scientific's weight within AIVL, moving from 0.2421% to 0.2122%, reflect a persistent re-evaluation by the AI management system. This pattern, occurring as BSX’s price plunged by 55.7% over the last year to its 52-week low of $44.33, signals the AI's discernment of a value trap rather than a genuine bargain. Despite a revenue growth of 17.44% and a 14.87% ROE, the AI likely flagged the lingering PBR of 5.83 and PER of 18.72, even at this reduced price, as still too high or indicative of future fundamental deterioration. This methodical reduction of exposure by WisdomTree’s AI-driven portfolio aligns with its mandate to identify and avoid such perceived mispricings within its US value-factor universe.

AIVL · Weight decrease · 5d

WisdomTree's AIVL, which employs an AI to distinguish genuine value from value traps within its approximately 100 US value stock holdings, initiated a series of weight reductions in Boston Scientific. The AI’s continuous assessment of fundamentals and valuation metrics likely flagged concerns about BSX, even as its price reached 42% of its 52-week high. Despite a 17.44% revenue growth, the company's relatively high PBR of 5.83 might have contributed to the AI's decision during a periodic rebalance to gradually decrease exposure, as the model aims for deep value. This pattern, observed through consecutive weight decreases from 0.2421% to 0.2183% over several days in June, suggests the system's active management to refine its value posture and avoid potential underperformers within its mandate.

AIVL · Weight decrease · 4d

WisdomTree's AIVL fund, employing AI to identify genuine value within its approximately 100-stock US value universe, reduced its weighting in Boston Scientific Corporation following a series of periodic evaluations. The AI's mandate to distinguish true value from value traps likely led it to reassess BSX, as certain valuation metrics, such as a PBR of 5.83, remained relatively high despite significant price depreciation. Even with BSX's 1-year return falling by 56.3% and the stock trading at 42% of its 52-week high, the model's comprehensive fundamental analysis (including margins, return on capital, and debt, alongside valuation) presumably signaled an increased risk or reduced value potential. This consecutive weight decrease, from 0.2420% to 0.2250%, indicates the AI's re-scoring of BSX led to a systematic adjustment during the fund's periodic rebalance cycle, aligning with its methodology of dynamically managing its pre-filtered US value pool.

AIVL, which employs AI to differentiate genuine value from value traps within its roughly 100 US value stock holdings, adjusted its exposure to Boston Scientific with a consecutive weight decrease ending June 12th at 0.2269%. This action suggests the AI’s fundamental and valuation analysis, which includes metrics like P/E and P/B, flagged BSX. Despite the stock’s current price being at its 52-week low and a 54.6% decline over the past year, the AI appears to have determined that its PBR of 5.83, for instance, still represents a valuation inconsistent with the fund’s definition of genuine value. This illustrates the strategy's focus on screening out value traps within its pre-filtered universe of value-factor names.

The precipitous reduction in holding from 1.6511% to 0.2371% suggests the AI's assessment of the stock's fundamental and valuation metrics, which inform its selection process for the ~100-stock portfolio, shifted during a periodic rebalance. This decisive action likely reflects a judgment that BSX's deteriorating price performance, including a -55.2% 1-year return, indicated a potential value trap rather than an undervalued opportunity. Minimal subsequent exposure and slight further adjustments suggest the AI's models continue to prioritize other opportunities within its rigorously screened universe.

BSX’s PBR of 5.83 and PER of 19.72, even alongside 17.44% revenue growth and 14.87% ROE, presented valuation metrics that AIVL’s AI component would meticulously evaluate against its specific value-factor criteria. WisdomTree’s AI, tasked with distinguishing genuine value from value traps using fundamentals and valuation metrics like P/E and P/B, would assess if these multiples represented a sustainable value proposition within its ~100 US value stock universe. The significant reduction in AIVL’s weight from 1.6511% to 0.2371% between May 15 and June 1 occurred while BSX's price continued its prolonged decline, registering a -19.9% 30-day return and a -48.5% 90-day return, now trading at $47.68, only 44% of its 52-week high. This movement indicates the AI determined BSX no longer met the necessary risk-adjusted value thresholds for a substantial allocation within AIVL's portfolio, prompting the sharp decrease in holding.

Buffett-style framework

Fails the frameworkas of Jul 19

AI ETFs PQUS and AIVL show recent increasing trends in their holdings of Boston Scientific, suggesting an accumulation or positive sentiment toward the stock. This contrasts with the framework's 'Fail' verdict, which is driven by a lack of sufficient financial transparency and an absent margin of safety from the available data.

  • Circle of CompetenceBoston Scientific operates in the health care equipment industry, which typically has predictable demand and unit economics, allowing for reasonable projection of cash flows.
  • Economic MoatThe company benefits from significant switching costs for medical professionals, a strong intellectual property portfolio, and regulatory barriers to entry, creating a durable economic moat.
  • ManagementThe provided data is insufficient to evaluate management's candor, capital allocation discipline, or skin in the game.
  • Financial HealthThe provided financials are insufficient to assess the 10-year average ROE, stability of operating margins, debt manageability, or owner earnings, and the single ROE point is just below the preferred threshold.
  • Margin of SafetyBased on the provided valuation multiples (PER, PBR, EV/EBITDA), there is no clear indication of a defensible discount to intrinsic value or a significant margin of safety.

Boston Scientific operates in a comprehensible area with a clear economic moat, passing initial framework stages. However, a significant lack of comprehensive financial data prevents a full assessment of its financial health and owner earnings. Furthermore, the current valuation multiples do not suggest a margin of safety, leading to an overall 'Fail' verdict.
