The Thesis
The news-sentiment strategy runs a simple, intuitive rule: buy names with positive recent news sentiment, exit when sentiment turns negative. It operates over a broad large-cap universe of 24 US equities spanning tech (AAPL, MSFT, GOOGL, NVDA), financials (JPM, BAC, V, MA), healthcare (JNJ, UNH, PFE, ABBV), staples (PG, KO, WMT, COST), and industrials/energy (CAT, HON, XOM, CVX). It is currently live.
The appeal is obvious — sentiment is a well-known short-horizon driver — but the appeal is also the risk: sentiment strategies can be whipsawed by noise and are only as good as the signal feeding them.
Recent Activity
The execution record tells two stories. Earlier this summer the strategy was active, putting on buys in AAPL (6 shares at 312.06 on May 31), MSFT (4 at 428.23), BAC (35 at 55.93), UNH (4 at 402.85), and GOOGL (5 at 360.40 on July 1). Since then, activity has stalled.
The last week of scheduled runs is telling: across September 1–7, every run executed zero trades, with one or two candidate orders rejected on most days. Cash sits pinned at $990.06 — the book is essentially fully invested — while total equity drifts between roughly $10,350 and $10,525. The strategy is holding, not trading. Whether the rejections reflect a lack of qualifying signals or a capital/sizing constraint is worth investigating, because a sentiment strategy that cannot act on new signals loses its edge.
Backtest & Validation
Here caution is warranted. The backtest over 451 days produced a total return of just 0.19% (final equity $10,018.55), a CAGR of 0.1%, a Sharpe of 0.74, and a shallow max drawdown of 0.05%. But it did so on only 2 trades with a 0% win rate — a sample far too thin to trust. Turnover of 36.5% and total fees of $2 confirm this was a near-dormant simulation.
Walk-forward validation makes the concern concrete: it did not pass. Of 4 folds, only 1 was positive — and folds 1 through 3 recorded zero trades each. All the backtest's activity and its entire 0.19% return came from fold 4 (Dec 2025–May 2026), which posted a 1.5 OOS Sharpe on 2 trades. The headline PSR of 0.923 looks encouraging, but the DSR of 0.551 across 6 trials, combined with only one active fold, signals that the result is not yet robust to overfitting.
The Verdict
The strengths are a sensible, explainable thesis and a broad, liquid universe. The risks dominate for now: the strategy trades rarely, its edge rests on a single validation window, and its recent live behaviour is dominated by rejected orders rather than executed conviction. Until it demonstrates activity across more folds and a larger trade count, treat news-sentiment as a plausible idea still hunting for statistical evidence — not a proven performer.
