What types of tools does Swoopr offer?

Swoopr's tool library spans six categories: calculators, screeners, simulators, comparison tools, checklists and scorecards, and research and reference tools. Calculators apply published formulas to user inputs. Screeners filter a research universe by defined criteria. Simulators show how a process behaves under changing assumptions. Comparison tools place consistent measurements side by side. Checklists organize process steps where procedure matters more than arithmetic. Reference tools help verify information from primary and official sources.

How do I choose the right tool for my question?

Start with the question rather than the tool name. Cost and fee questions suit fee calculators, compounding projections or affordability tools. Risk and loss questions suit position-sizing, drawdown, stress-test or scenario tools. Comparison questions suit side-by-side tools with methodology notes. Screening questions suit universe-filtering tools followed by document review. Rule and reference questions suit source-verification tools that link to the governing authority.

Do Swoopr tools provide personalized investment advice?

No. Swoopr tools are educational calculators, screeners, simulators, and research aids. They do not know your full financial situation, goals, tax status, time horizon, or risk capacity, and they cannot make a recommendation suitable for any individual's circumstances. Tool outputs are estimates, models, or organized information, not personalized advice.

What does data currency mean in a market-data tool?

Market data currency describes the time at which price, rate, or figure was last refreshed. It can mean real-time, delayed, end-of-day, previous close, or manually entered data. Every Swoopr tool using external market or economic data displays a timestamp or data-currency note near the output. If data is unavailable, the tool shows an explicit unavailable state rather than silently retaining a stale value.

Investment Education, Research & Tools for Smarter Decisions.

Swoopr's free investment tools help you test assumptions, understand formulas, compare choices, and investigate market or portfolio questions without turning a calculator result into a recommendation. Every tool connects to the canonical concept it implements, the assumptions it uses, and the guide that explains when the output is useful. The library includes research tools, stock and fund screeners, risk and position-sizing calculators, retirement and portfolio tools, market visualizations, rule and reference tools, and educational simulators. Each tool states what it calculates, which inputs matter, where any external data comes from, and the limitations that can change the result.

Key Takeaways

Use a calculator when the answer depends on assumptions you can change.
Use a screener to narrow a research universe, not to outsource the final decision.
Check the methodology before comparing outputs from two different tools with the same label.
Treat model outputs, scores, simulations, and projections as estimates rather than facts.
Check timestamps and data-source notes when a tool uses market or economic data.
Follow the related learning guide when you do not understand an input, formula, or limitation.

How Swoopr Tools Should Be Read

A tool can make a financial concept easier to explore, but precision in the interface does not guarantee certainty in the result. There are four broad kinds of output in the Swoopr tool library.

Deterministic calculations

These apply a published formula to the inputs you provide. Examples include percentage changes, position-size math, fee calculations, and other arithmetic relationships. The formula can be exact while the assumptions you enter remain uncertain. The formula and assumption registry documents each formula's inputs, rounding behavior, and stated assumptions.

Market-data calculations

These combine a formula with external market or reference data. The result depends on the provider, field definition, adjustment policy, coverage, and data timestamp. The tool identifies whether the data is real-time, delayed, end-of-day, or otherwise limited whenever that distinction matters.

Scenario models

These let you explore what happens if assumptions change. A retirement projection, sequence-of-returns simulation, valuation model, or compounding scenario is not a prediction. It is a structured "what if?" calculation.

Screening and scoring systems

These organize a large research universe by defined criteria. A screen can help you find candidates. A score can summarize selected inputs. Neither proves that the highest-ranked security is the best investment.

Tool selection decision tree: start with your question type (cost projection, risk assessment, comparison, screening), then branch to the matching Swoopr tool category.

Choose a Tool by the Question You Have

"How much could this cost me over time?"

Start with fee, tax, inflation, compounding, or opportunity-cost tools.

"How much risk am I taking?"

Use position-sizing, drawdown, diversification, volatility, sequence-risk, or scenario tools.

"How do these investments differ?"

Use comparison tools, then read the assumptions behind the comparison.

"What companies or funds meet these conditions?"

Use a screener as the beginning of research, then open filings, fund documents, and the Research Workbench.

"What does this market signal mean?"

Use the visualization or indicator tool alongside the relevant educational guide. Do not use a single signal as a stand-alone prediction.

"What rule or limit applies?"

Use a Swoopr reference tool, then follow the link to the regulator or government source that governs the rule.

The Six Tool Families

Swoopr's library organizes tools into six functional families. Knowing which family fits your question helps you interpret the output correctly.

Calculators

Calculators apply published formulas to user-entered or sourced inputs. Their strength is transparency: a position-size calculator shows exactly how account risk, entry price, stop price, fees, and slippage combine. A bond calculator shows how coupon, maturity, price, and yield interact. The formula can be mathematically exact while the inputs remain uncertain.

Screeners

Screeners filter a research universe. They find stocks, ETFs, REITs, or other instruments meeting defined criteria. A screener is not a ranking of investment quality unless the methodology explicitly defines and justifies a ranking. A robust screener states what happens when data is missing, whether fields are comparable across industries, and when the underlying data was last refreshed.

Simulators

Simulators show how a process can behave. A limit-order fill simulator, leveraged ETF decay model, auction model, or sequence-of-returns scenario is educational because you can change one factor and see the consequence. The useful question is "what relationship is this demonstrating?" not "what will happen next?"

Comparison tools

Comparison tools place consistent measurements side by side. Two ETFs can have the same expense ratio but different tracking behavior, spreads, tax structures, or liquidity. Two companies can have similar P/E ratios but different capital structures and earnings quality. A comparison tool provides field definitions, comparability notes, and links to the deeper concept guides.

Checklists and scorecards

Checklists are useful when process matters more than a single formula. Security reviews, strategy-readiness checks, due-diligence flows, and operational controls fit here. A scorecard becomes risky when a composite score hides value judgments. Swoopr shows component evidence so you can see how each criterion affects the result before accepting a summary.

Research and reference tools

Research notebooks, filing locators, source explorers, market calendars, and rules-and-reference tools help you verify information rather than calculate an investment outcome. These tools strengthen the evidence chain and connect directly to primary sources and Swoopr's research methodology.

Market Data and Timestamps

"Current" data can mean several things. A quote may be real-time, delayed, end-of-day, previous close, or manually entered. Fundamental data may come from the latest filing while a consensus estimate comes from a different provider and date. Two tools using "current earnings" can disagree when their providers update at different times.

Every Swoopr market-data tool displays the relevant timestamp near the output. Historical series disclose adjustment policies when splits, dividends, or corporate actions affect continuity. If data is unavailable, the tool shows an explicit unavailable state rather than silently retaining a stale value.

How Swoopr Tools Connect to the Education Library

A calculator can produce a number quickly, but the number is only useful when you understand the assumptions behind it. Swoopr connects interactive tools to the educational material that explains the underlying concept, formula, limitations, and decision context.

When a tool implements a defined formula, the related guide should explain each input and show at least one worked example. When a tool uses market or economic data, its page identifies the source, timestamp, adjustment policy, and any delay that can affect the result. When a tool models a scenario, the output should be presented as a conditional result rather than a prediction.

Use the tool to explore the question. Use the related guide to understand why the result changes. Use primary sources when a rule, filing, tax provision, regulatory requirement, or official market definition controls the answer.

Before relying on a result

Check four things:

Inputs: Are the values current, complete, and expressed in the expected units?
Assumptions: Does the model assume a constant return, tax rate, volatility, correlation, growth rate, or other uncertain value?
Data: Is the result based on live, delayed, end-of-day, historical, user-entered, or illustrative data?
Limitations: What important real-world condition does the calculation leave out?

A precise-looking output can still be highly sensitive to uncertain inputs. Swoopr tools are designed to make those assumptions visible rather than hide them.

Educational Limitations

Swoopr tools provide structured information, not individualized investment, tax, or legal advice. A portfolio tool does not know the full household balance sheet unless you enter it. A retirement calculator cannot know future returns, inflation, taxes, health costs, or lifespan. A valuation model cannot know future cash flows. A strategy simulator cannot prove a trading edge will persist. A screener cannot decide whether an investment fits any individual.

These limits appear as part of each tool, not in a footnote. When a tool's output depends on assumptions you entered, the label reflects that. When it depends on external data, the tool identifies the source, field definition, and timestamp. A result with visible assumptions is easier to audit and less likely to be mistaken for an observed fact.

Privacy and Local Storage

When a tool runs entirely in the browser, computation happens on your device and inputs are not transmitted unless the tool explicitly needs a server request for external data. Tools that store a journal, watchlist, portfolio snapshot, or imported file locally display where the data lives and how to clear or export it.

When a tool requires server-side data, user inputs are separated from data provider requests and no information is collected beyond what the calculation requires. Real-time or delayed market data requests include only the identifiers needed for that query, not session or personal state.

Accessibility Standards for Swoopr Tools

An accessible financial tool works without requiring dragging, hovering, or color distinction alone. Every input carries a programmatic label, unit description, error announcement, and useful help text. Validation errors are announced via accessible live regions and do not clear valid fields. Dynamic results use live-region strategies that inform assistive technology without overwhelming a screen reader on every keystroke.

Charts carry text equivalents or accessible data tables. Sliders have keyboard-operable numeric inputs. Tables carry explicit headers. Focus moves only when the interaction requires it, not because a background result updated. The methodology behind any tool output is readable without interacting with the visualization.
