Research education

Learn stock research without pretending markets are simple.

Sigma Terminal is built around structured research: what a business does, what the market expects, what could go right, what could go wrong, and what risk you are actually taking. This guide gives you the same mental model in plain language.

Start with the business, not the ticker.

A chart can show where price has been. Research asks why the company deserves attention at all.

Business quality

Know how the company makes money.

Identify the revenue lines, customer base, margin profile, competitive position, and balance sheet pressure. A useful research note should explain the business in a few sentences before it argues about price.

Expectations

Separate performance from surprise.

A good company can fall if expectations were already aggressive. A challenged company can rally if results are less bad than feared. Compare current valuation, guidance, and consensus expectations before forming a view.

Time horizon

Name the clock you are using.

A one-week catalyst trade, a six-month earnings revision idea, and a five-year compounder thesis need different evidence. Mixing horizons is one of the fastest ways to make a research process noisy.

Turn a thesis into bull, base, and bear cases.

A thesis is not only a sentence like "the stock is cheap" or "AI demand is strong." It should be a range of possible outcomes with evidence attached to each path. Scenario work helps you avoid treating one attractive story as the only future.

Base case

The base case is the ordinary path: what might happen if the company performs close to current expectations. It should include revenue direction, margin assumptions, balance sheet needs, likely catalysts, and a valuation range that does not require heroic assumptions.

Bull case

The bull case asks what could justify upside. Examples include faster revenue growth, durable margin expansion, new product adoption, lower capital intensity, better cash conversion, regulatory relief, or a valuation multiple that expands because investors trust the story more.

Bear case

The bear case asks what could break the thesis. Examples include demand slowing, pricing pressure, customer concentration, rising debt costs, dilution, execution misses, inventory problems, or a stock that already discounts perfection.

Terminal habit

Before acting on a stock, write one sentence for each scenario. If you cannot describe the bear case clearly, the research is not finished.

Risk is decided before the trade.

Risk controls are not a pessimistic add-on. They are the operating system for staying rational when price moves fast.

Position sizing

Size by downside, not confidence.

Position size should reflect the distance to your invalidation point, the volatility of the asset, liquidity, and how correlated the idea is with the rest of your portfolio.

Risk/reward

Make the trade-off visible.

A risk/reward ratio compares estimated upside to estimated downside. It does not guarantee anything; it forces the question of whether the potential payoff is worth the defined risk.

Stop loss

Define what proves you wrong.

A stop loss can be price-based, thesis-based, or time-based. The important part is deciding in advance which evidence invalidates the setup.

Keep a research log.

A research log makes your process measurable. Record the date, ticker, thesis, expected catalyst, bull case, bear case, valuation range, planned risk, and what would change your mind. Later, review whether the outcome came from skill, luck, a changed market regime, or a flawed assumption.

Sigma Terminal is designed for this style of thinking: repeatable prompts, structured outputs, and plain-language scenario analysis. The goal is not to remove uncertainty. The goal is to make uncertainty easier to inspect.
