Thesis check
Three beats in four quarters support execution quality. The open question is whether the current valuation already prices in that durability.

The investor workflow
From ticker to decision—without losing the plot.
A serious research process should connect the company, the market, and the portfolio. Stackz keeps that chain intact from the first question to the final scenario.
Company dossier
Build the evidence stack
Bring catalysts, news, signal context, and the open questions around the thesis into a single research surface.
Measure portfolio fit
See whether the idea adds diversification or quietly doubles down on the same sector, factor, or concentration risk.
Pressure-test the decision
Use scenarios, backtests, portfolio optimization, and income projections to examine what could happen next.
Research workstation
The full quarter, not the headline.
Price alone does not tell you whether a company is executing. Stackz organizes the earnings path, estimate history, valuation context, and portfolio impact into a repeatable review.
One symbol · multiple research lenses
Quarterly earnings tape
Review EPS estimates against actual results, surprise direction, historical cadence, and the next reported earnings date.

Income & capital return
Inspect dividend history, yield, payout context, your received income, and DRIP projections alongside the core company research.
Portfolio-aware conclusion
Carry the company view into concentration, correlation, sector exposure, tax context, and scenario analysis tied to the positions you hold.

Less noise. More traceable thinking.

Why Stackz exists
The research should get sharper as you move from stock to portfolio—not reset.
Stackz is built to keep the company thesis, the market evidence, and the investor's real exposure in the same conversation. The software does the organizing and analysis. You keep the judgment.

Trust boundary
Your research desk should not control your money.
Stackz analyzes account and market information. It is deliberately separated from the ability to trade, withdraw funds, or move cash.
Brokerage credentials stay with Plaid. Stackz receives read-only portfolio information.
Stackz cannot place a trade, withdraw funds, or move cash from a linked account.
Portfolio records are protected in transit and at rest, with account-level access controls.
Payment details are handled through Stripe rather than stored in the research workspace.
Before you open the desk
Questions serious investors ask.
Stackz is an educational research and analytics product. It helps organize evidence and model possibilities; it does not make the investment decision for you.
What can I research on a stock page?
The company workspace brings together price history, technical indicators, dividends, valuation context, and quarterly earnings history including estimate-versus-actual results and earnings surprises. Availability can vary by security and data source.
How is this different from a market-data terminal?
Stackz connects company research to your actual portfolio. The goal is not simply to show more data, but to help you see how a thesis affects concentration, income, correlation, risk, and the scenarios you care about.
Can Stackz trade or move my money?
No. Stackz uses read-only brokerage data and cannot place trades, withdraw funds, or move cash.
Do I need a credit card to start?
No. Pro starts with a free 15-day trial without a credit card.
Which brokerages work?
Stackz uses Plaid, which supports many major US brokerages. Availability depends on the institution and account type.
Does Stackz replace primary-source research or investment advice?
No. Stackz AI provides educational analytics for self-directed investors. Confirm material information with company filings and other primary sources, and use qualified professional advice when you need it.
What happens after the trial?
You can choose an available paid plan, cancel, or remain on the Free plan. Current prices are shown above.
Open the desk. Bring your next question.
Research the company, examine the quarter, and see the portfolio consequence before you make the call.
