The thesis
The news-sentiment strategy runs a simple, intuitive playbook across a 24-name large-cap universe (AAPL, MSFT, GOOGL, NVDA, JPM, the payment networks, healthcare, staples, and energy): buy when recent news sentiment turns positive, exit when it turns negative. It's the kind of idea that sounds robust — headlines move stocks, so lean into the flow. The strategy is currently marked live.
Recent activity
The live account has been quiet. Scheduled runs from 2026-08-26 through 2026-09-02 executed zero trades, with the occasional rejected order (one each on 08-28 and 09-01). Cash has sat flat at $990.06 while total equity drifted between roughly $10,320 and $10,465 — pure mark-to-market on positions opened earlier.
Those positions came in a cluster between late May and early July 2026: buys in AAPL (6 @ $312.06), MSFT (4 @ $428.23), BAC (35 @ $55.93), UNH (4 @ $402.85), and GOOGL (5 @ $360.40). Since then, the sentiment signal simply hasn't fired. There are no exits on record — the "sell on negative sentiment" half of the thesis is untested in this window.
Backtest and validation
This is where caution is warranted. The backtest returned +0.19% over 451 days (CAGR ~0.1%), finishing at $10,018.55 — effectively flat. The upside: a tiny 0.05% max drawdown and low fees ($2 total). The problem: the whole result comes from just 2 trades, and win rate reads as 0. Sharpe of 0.74 on two trades is more noise than signal.
Walk-forward validation did not pass. Of four folds, only one was positive — and folds 1 through 3 recorded zero trades each. Every unit of return, and the flattering 1.5 out-of-sample Sharpe, comes from fold 4 (Dec 2025–May 2026) alone. The headline PSR of 0.923 looks reassuring, but the deflated Sharpe (DSR) drops to 0.551 once the 6 trials are accounted for, and with a two-trade sample these statistics carry little weight.
Strengths
- Capital discipline. It doesn't overtrade or chase; the 0.05% drawdown reflects genuine risk restraint.
- Quality universe. When the signal did fire, it bought defensible large-caps, not lottery tickets.
Risks
- Almost no signal. A sentiment strategy that trades twice in 451 backtest days — and not at all across three of four validation folds — is barely a strategy yet. It may be mis-calibrated, or the sentiment threshold is set too high.
- Single-fold dependence. One favorable fold is doing all the work. That is the textbook setup for overfitting, which is exactly why the validation gate flagged it.
- Untested exits. No negative-sentiment sells have occurred, so half the thesis is unproven.
Verdict
news-sentiment is low-harm but also low-conviction. Before reading anything into its live equity, we'd want the signal firing far more often and surviving more than one fold. Right now it's a promising idea awaiting evidence — not a validated edge.
