The thesis
The news-sentiment strategy runs a simple, intuitive idea: buy names with positive recent news sentiment and exit when sentiment turns negative. It operates over a 24-name large-cap universe spanning tech, financials, healthcare, staples, and energy — AAPL, MSFT, NVDA, JPM, JNJ, XOM, and the usual blue-chip company. It is currently live.
As theses go, this one is defensible. Sentiment-driven entries are well-trodden ground, and anchoring to a liquid, diversified universe keeps execution risk low. The problem is not the idea — it is how rarely the idea fires.
Recent activity
The strategy's daily scheduled runs tell the story plainly. Across the last week of trading (24 Sep through 1 Oct), every single run executed zero trades, while several logged rejections — two on 24 and 25 Sep, one on 28 Sep. Cash has sat frozen at $2,036.71 the whole time, with total account value drifting between roughly $10,155 and $10,275 purely on mark-to-market moves.
The last real activity was 23 September, when it rotated out of a 35-share BAC position at $55.96 and into 4 shares of NVDA at $225.34. Before that, the summer saw a cluster of entries — AAPL, MSFT, BAC, UNH, and GOOGL — spread from late May to early July. So it does act when conviction appears; it just does not appear often.
Backtest and validation
Here is where caution is warranted. Over a 451-day backtest the strategy placed just 2 trades, returned 0.19% (a 0.1% CAGR), and posted a 0% win rate. Sharpe was 0.74 against a tiny 0.05% max drawdown, with $2 in fees and no FX cost. A near-zero drawdown looks reassuring until you realise it reflects almost no exposure rather than skilled risk control.
Crucially, validation failed. Of four walk-forward folds, only the final one (16 Dec 2025 – 29 May 2026) traded at all — 2 trades, 0.19% return, a flashy 1.5 Sharpe. The other three folds placed zero trades and returned nothing. A probabilistic Sharpe of 0.923 and deflated Sharpe of 0.551 across 6 trials cannot rescue a track record that is, functionally, one lucky window.
Strengths and risks
Strengths: a clean, explainable thesis; a liquid universe; negligible fees and drawdown; and a disciplined willingness to stay in cash rather than force trades.
Risks: the sample is simply too thin to trust. Two trades and a 0% win rate mean every headline metric rests on noise, and the failed, single-fold-positive validation says the edge has not been demonstrated out of sample. The daily rejections also hint at friction — orders the strategy wants but cannot place — that deserves a closer look.
Verdict: promising plumbing, unproven signal. news-sentiment needs either a more sensitive trigger or a longer live record before anyone should size it up.
