A Stock Research Checklist Before You Buy
A checklist cannot determine whether a stock is a good investment. It can prevent a promising narrative from skipping the questions that matter.
Understand how the company makes money
Identify the products or services producing revenue, the customers who pay, and the costs required to serve them. Note customer, supplier, geographic, and product concentration.
Read the financial direction
Compare several periods. Review revenue, margins, cash generation, dilution, debt maturities, working capital, and recurring adjustments together—not one quarter in isolation.
Ask what the market expects
A strong company can disappoint when expectations are stronger. Treat valuation as the price attached to assumptions and write those assumptions down so they can be tested.
Name risk plainly
Ask what could permanently weaken earning power or force unfavorable financing. Separate company risk from portfolio risk; even a carefully researched idea can be too large for its uncertainty.
Record the decision
Before acting, record the thesis, strongest counterargument, invalidation evidence, and review date. A good process cannot guarantee profit, but it creates a repeatable way to learn.
