The Thesis
News-sentiment is one of our more intuitive strategies: buy on positive recent news sentiment, exit on negative. It hunts across a 24-name universe of large-cap blue chips — the FAANG-adjacent tech leaders (AAPL, MSFT, GOOGL, NVDA), financials (JPM, BAC, V, MA), healthcare (JNJ, UNH, PFE, ABBV), staples, and energy. It is currently running live.
The appeal is obvious. Sentiment is fast-moving and, in theory, front-runs price. The concern is equally obvious: news is noisy, sentiment scoring is imperfect, and crowded large caps price information quickly.
Recent Activity
The strategy was active early in the summer, executing five buys between late May and 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 it has gone quiet — every scheduled run from July 28 through August 4 logged 0 executed, 0 rejected, with cash parked at $990.06 and total paper equity drifting between roughly $10,193 and $10,573 on mark-to-market alone.
That is a strategy holding, not trading. Whether that reflects genuinely neutral news flow or a signal that simply isn't firing is the open question.
Backtest and Validation
The headline backtest looks calm to the point of inertia: +0.19% total return over 451 days, a 0.74 Sharpe, a trivial 0.05% max drawdown, and just 2 trades with a 0% win rate. CAGR rounds to 0.1% and turnover sits at 36.53%. Fees were a rounding error ($2, no FX cost).
The deeper validation is where the caution flag goes up. It did not pass. Of four walk-forward folds, only the most recent (Dec 2025–May 2026) traded at all — and it carried the entire result, posting the same 0.19% return and a healthy 1.5 out-of-sample Sharpe. The three earlier folds were completely dormant: zero trades, zero return.
The statistical picture is genuinely mixed. The PSR of 0.923 is encouraging, and the OOS Sharpe of 1.5 is real. But the DSR of 0.551 is only modestly above coin-flip, and with just 2 trades underpinning everything across 6 trials, we are drawing conclusions from almost no data.
Verdict
Strengths: disciplined, low-turnover, tiny drawdown, and a strong PSR with a legitimately good showing in its one active fold. Risks: the sample is far too thin to trust, three of four folds never fired, the win rate is zero, and live trading has stalled. This is a plausible edge that has not yet earned confidence. Until it trades enough to prove the signal is more than a single lucky fold, treat it as a watch-list candidate, not a conviction allocation.
