XLC — XLC | S&P 500 Communication Services Sector ETF 13F holdings and portfolio analysis

Following the baseline means accepting a very top-heavy communication-services portfolio with near-market beta and meaningful single-name dependence. In the strategy artifact, top 5 concentration is 50.22%, top 10 is 76.7%, and sector weight is 100.02% Communication Services. META alone is 22.97%, GOOGL is 9.9%, and NFLX is 6.35%. The backtest produced 10.6% annualized return and 112.51% total return, but alpha stayed negative at -1.27 and max drawdown reached -47.83%, so the exposure is concentrated sector upside with benchmark-like market risk and weak relative efficiency.

The recent baseline trade-off is best illustrated by a few strong and weak months with different turnover profiles. In 2025-05-31, optimizedReturn was 5.79% versus benchmarkReturn 3.75% for +2.04% excess with only 0.94 turnover. In contrast, 2025-06-30 lost the relative plot: optimizedReturn was -3.69% versus benchmarkReturn 2.69%, a -6.37% excess gap, with turnover 13.97. September 2025 was another weak stretch, with optimizedReturn -4.67% against benchmark 2.05% for -6.72% excess at 9.81 turnover. Those swings help explain why total returns stayed respectable, but Sharpe remained only 0.56 and drawdown still hit -47.83%.

The next checks should be concentration, implementation burden, and which names drive recovery risk. The baseline artifact flags top holding risk explicitly, with META near 22.97% and top 10 concentration at 76.7%. It also required 1,945 trades and totalEstimatedCost of 1.3501, so implementation frictions are not trivial. Finally, because maxDrawdown was -47.83% and recoveryDays were 417, a user should inspect the NAV and drawdown series around the worst decline to see whether the rebound was mostly driven by META, GOOGL, and NFLX or by broader holdings.
