Build an investment decision from evidence, context, analysis, and execution.
Use this page to move from primary evidence and market context to analysis, verification, implementation, and review.
Trace the claim to the source before acting on it.
Build one decision from facts, context, analysis, and execution.
A complete investment process uses several layers of information. Learn what each layer can answer, what it cannot answer, and how to combine them without confusing a data point, a headline, or a chart with a decision.
Read the underlying economics
Start with the business model, financial statements, ownership, debt, cash flow, fund holdings, costs, index methodology, and product terms. Build the facts before forming a view. Then record which facts are primary, which are estimates, and which assumptions must hold for the thesis to work so the research can be reviewed later.
Build a company research process →Read price, liquidity, and expectations
Use quotes, spreads, volume, valuation ratios, yields, options data, historical prices, and peer comparisons to understand how the market is pricing the asset today. Separate the current market quote from your estimate of value and from the price at which the position can actually be executed at the intended size.
Understand the market behind the quote →Separate new information from narrative
Track earnings, economic releases, corporate actions, policy decisions, and industry developments. Ask what changed in expected cash flows, risk, or discount rates, not whether the headline sounds positive or negative. Record the prior expectation before judging the release; a strong headline can still disappoint if the market expected more, and a weak headline can be less negative than feared.
Build a repeatable market review →Use tools to organize attention
Screeners narrow a universe; charts show price, volume, volatility, and trend. They help identify questions and implementation levels, but the final decision still requires a thesis, risk limit, and review rule. A tool should reduce missed steps and arithmetic errors, not replace judgment; every output should point back to an input, assumption, source fact, or written rule.
Use charts as evidence, not a verdict →Understand a U.S. trade from order entry to settlement.
Follow the trade through venue selection, execution, clearing, settlement, financing, regulation, and cost.
U.S. Market Guide: the mechanics behind the transaction
Learn how exchanges, brokers, order types, market safeguards, T+1 settlement, margin, short selling, regulators, and fees connect in one operating process. By the end, you should be able to trace an order through quotes, routing, execution, clearing, settlement, records, and account protections instead of treating trading as a single button press.
Read the complete guideRead a company before reading the chart.
Connect the business model, filings, cash flow, balance sheet, valuation, and thesis checkpoints before using price action as context.
PORTFOLIOGive every holding a job.
Assign each holding a role, target range, liquidity purpose, and rebalancing rule tied to the goal.
RISKMeasure more than volatility.
Review drawdown, concentration, correlation, liquidity, leverage, gap risk, and operational failure before sizing exposure.
SYSTEMSTurn ideas into rules that can be tested.
Turn a hypothesis into testable rules for data, entry, exit, sizing, costs, validation, and failure conditions.
TOOLSCheck the arithmetic before the decision.
Use calculators and checklists to expose assumptions, verify arithmetic, and document what needs review before acting.
