Baseline
Analysis messagesPre-generated Q&A about this fund. Use as reference context for your own analysis.
Directly following the baseline exposes an investor to a concentrated large-cap portfolio with meaningful single-name and sector risk, moderate implementation activity, and below-benchmark alpha. The top 10 holdings make up 55.13% of assets, with GS at 11.26%, CAT at 7.34%, and MSFT at 6.19%. In the baseline strategy view, annualized return was 11.63% and total return 197.04%, but alpha was -0.66 and max drawdown still reached -37.07%. Risk notes also flag 3,500 trades and 0.6886 estimated total cost, so even the plain disclosed-following approach is not costless in backtest terms.
The recent baseline periods that best explain the trade-off are the weak alpha months where turnover stayed elevated despite mixed absolute returns. In 2025-04-30, the baseline returned 3.96% but still lagged SPY by -2.32%. In 2025-06-30, it returned 0.81% with -1.88% excess return, and in 2025-08-31 it gained 2.26% but trailed by -1.40%. There were better relative months like 2025-02-28 (+1.31 excess), 2025-07-31 (+1.15), and 2025-11-30 (+1.29), but the overall pattern of frequent small benchmark misses helps explain why alpha stayed negative despite an 11.63% annualized return. Turnover also remained noticeable, ranging from 0.78 to 1.72 in several 2025 monthly periods.
Before accepting the baseline, the user should inspect three things: concentration, sector transparency, and benchmark-relative period behavior. Concentration is material because top 5 holdings are 34.02% and top 10 are 55.13%. Sector transparency also matters because the static snapshot’s main sector table shows 66.8% in "Others," while the baseline artifact’s sector breakdown resolves that into Financials 28.34%, Information Technology 20.23%, Industrials 14.67%, and Health Care 12.42%, which is much more informative for risk review. Finally, period-level excess returns should be checked because several 2025 months had positive returns but still lagged SPY, which is exactly how a portfolio can look acceptable in isolation but still fail a benchmark-aware standard.
