Thesis
The news-sentiment strategy runs a simple, intuitive premise: buy names showing positive recent news sentiment, exit when sentiment turns negative. It operates over a 24-name large-cap universe spanning tech, financials, healthcare, staples, and energy — AAPL, MSFT, GOOGL, NVDA, JPM, V, JNJ, XOM, and peers. The logic is easy to reason about, which is a virtue for a public strategy. Whether it produces a tradable edge is a separate question, and the data urges caution.
Recent Activity
Operationally, the strategy is currently idle. Every scheduled run from August 7 through August 14 reports 0 executed, 0 rejected, with cash pinned at $990.06 and paper-account total drifting between roughly $10,365 and $10,506. The account is fully invested from earlier positions — the last executed orders were a cluster of buys in late May through early July: AAPL (6 sh @ $312.06), MSFT (4 @ $428.23), BAC (35 @ $55.93), UNH (4 @ $402.85), and GOOGL (5 @ $360.40). Since then, sentiment has apparently not crossed a threshold sharp enough to trigger either adds or exits. That is a coherent outcome for a sentiment gate, but it also means the live book is coasting rather than actively expressing the thesis.
Backtest & Validation
Here the picture gets thin. The backtest closes at a final equity of $10,018.55 — a ~0.19% total return over 451 days, a ~0.1% CAGR, on just 2 trades and a reported win rate of 0. Sharpe is 0.74, max drawdown a contained 5%, turnover 36.5%, and total fees a trivial $2. A 0.19% return over more than a year is not an edge; it is closer to flat.
Walk-forward validation makes the fragility explicit: it did not pass. Of four out-of-sample folds, only one was positive — and folds 1 through 3 recorded literally zero trades and zero return. The entire result comes from fold 4 (Dec 2025–May 2026), which posted 0.19% and a 1.5 Sharpe on two trades. The probabilistic Sharpe (PSR 0.923) and deflated Sharpe (DSR 0.551, across 6 trials) look respectable on paper, but they are describing a sample of essentially one active window. Statistics computed on two trades should carry a large mental error bar.
Assessment
Strengths: a transparent, defensible thesis; low turnover; small drawdown; and near-zero trading cost. Risks: the strategy is severely under-active, its performance is concentrated in a single fold, and validation failed. The 0-of-3 dormant folds suggest the sentiment trigger may be miscalibrated — too conservative to engage most regimes. Before treating any of these numbers as evidence of skill, the sentiment threshold and signal frequency need review; right now the record reflects inactivity more than insight.
