What it does

Three honest reads on any stock.

Each panel answers a different question — none of them are "what should I buy." That's deliberate.

Rewind pattern analog

Finds the closest historical windows to a stock's recent chart pattern using z‑normalized trailing returns, then shows the distribution of what happened over each horizon.

Volatility regime forecast

Walk‑forward logistic model on HAR features. Reports the probability of high vs calm volatility — alongside its real accuracy and the two naive baselines it must beat.

Model Persist Calm AUC

Relative ranking

Cross‑sectional percentile against your loaded universe on momentum, trend, low‑volatility, RSI, and 52‑week‑high proximity. Click any factor for the leaderboard.

The honest part

Most stock apps tell you what to buy. We tell you what the data says — and how well we know.

Every "stock prediction" app you've ever seen has the same gap: no real out‑of‑sample accuracy, no baselines, no honesty about where signal ends and noise begins. Stock View is built the other way.

  • Walk‑forward validated. Every metric is computed on data the model never saw during training.
  • Beats two baselines, or it says so. Persistence ("today again") and Always‑calm ("the more common regime") — if we don't beat both, the verdict isn't green.
  • AUC reported, not hidden. 0.5 = no skill, 1.0 = perfect. Always visible next to every forecast.
  • Direction calls have no reliable edge — and we say so. Single‑stock direction is presented as an outcome distribution + base rate, never as a buy/sell.

Questions

Frequently asked.

How does Rewind actually work?

Rewind z‑normalizes a stock's trailing returns over a horizon‑scaled lookback window, then computes Euclidean distance against every comparable window in 5 years of historical data. The closest matches become "analogs." For each analog we record what happened over the next 5/10/22 days, then show you the resulting distribution — its mean, its 25–75% range, the up‑rate, and how that compares to the stock's overall base rate. The honest read is the spread, not the average.

Is this financial advice?

No. Stock View is desktop analytics and visualization software for educational and informational purposes only. We are not a registered investment advisor. The app explicitly does not provide buy/sell recommendations. Past performance never guarantees future results. Always consult a qualified financial advisor before making investment decisions.

What makes this different from other stock apps?

Most stock‑prediction apps don't show out‑of‑sample accuracy, never compare against naive baselines, and don't tell you when a forecast lacks edge. Stock View does all three — every forecast is walk‑forward validated, baselines are visible alongside the model, and any panel without real edge says so explicitly.

What markets does it cover?

Stock View focuses on US large‑cap equities (S&P 500). All technical analysis, screeners, ranking, and Rewind patterns operate on US‑listed stocks. International coverage may follow based on demand.

How many devices does a desktop license cover?

Every plan — Monthly, Annual, and Lifetime — activates on 1 computer. If you replace or move machines, free the seat first from inside the app via License → "Deactivate this device," then activate on the new one. There's no limit on how many times you can move the same license between your own computers, only on how many are active at once.

Can I cancel anytime?

Yes. The iOS subscription is managed by Apple — cancel anytime in Settings → your Apple ID → Subscriptions. The desktop subscription is managed through your purchase receipt or by emailing support@stockviews.online. In both cases your license remains active until the end of the period you paid for.

Refunds?

For desktop purchases: within 14 days of purchase, email support@stockviews.online and we'll process a refund and revoke the license. iOS refunds are handled through Apple per their App Store policies.

Do you connect to my brokerage?

No. Stock View never connects to a brokerage account, never places trades, and never holds funds. It's a read‑only analytics tool that fetches public market data and runs computations locally.
