In short
Stock research tools for long-term investors should test the boring hypothesis first, because the boring hypothesis usually wins: in our historical illustration, the classic AAPL golden cross timing rule UNDERPERFORMED simply buying and holding, and AgentTrading stamps that verdict instead of hiding it. That is the tool working as designed. Paste a ticker and it summarizes the fundamentals like a patient analyst, revenue trajectory, margin direction, valuation against the company's own history, with at least one risk flag it insists on including; attach any timing or screening rule and it backtests the idea on 20+ years of split- and dividend-adjusted daily data, dividends reinvested, with a 0.1% cost per trade assumed by default. The manual version of that loop, a screener, ten filings, and a spreadsheet, runs 4 to 6 hours per idea; the bench runs it in minutes with every assumption logged. Portfolio Visualizer ($0 to $55 per month) computes similar statistics but hands you a form and a table with no explanation; AgentTrading starts at $19 per month, and explains the result. One honest limitation: coverage is US-listed stocks and ETFs, so international holdings sit outside the bench. Nothing here is a recommendation: educational analysis with the assumptions visible, and the holding decision stays yours.

What changes when the vetting is honest
Buy-and-hold is the benchmark, always
Every rule is tested against simply holding, and when holding wins the verdict says UNDERPERFORMED. The AAPL golden cross graded exactly that way in our historical illustration, which is the honesty this page is named for.
Fundamentals like a patient analyst
Revenue trajectory, margin direction, valuation against the company's own history, and a mandatory risk flag, each stated as a checkable claim drawn from public filings rather than an unexplained score.
Drawdowns you can imagine sitting through
The risk panel describes the worst stretch in words: how deep it went, how long it lasted, how long recovery took. Holding for a decade is easy until year three; the panel is honest about year three.
Minutes per idea, every assumption logged
The screener-filings-spreadsheet loop takes 4 to 6 hours per idea. The bench runs it in minutes and logs date range, parameters, and costs, so the research file survives longer than the enthusiasm.
THE MATH - TIME, NOT MAGIC
The manual loop is 4 to 6 hours per idea
A screener, ten filings, and a spreadsheet backtest, for every single idea. The bench runs the same loop in minutes and logs what it assumed. Count what that is worth in your week.

On the same bench
AI stock analysis is the fast per-ticker read, and the fundamental analysis tool goes deeper on filings. Income investors testing a payout strategy on total return should start with dividend backtesting. The drawdown language on every run comes from investment risk analysis, and allocation-level ideas get the same treatment on the ETF backtesting page.
QUESTIONS - ASKED AND ANSWERED
Long-term investors: the common questions
What research tools do long-term investors actually need?
Fundamentals with enough history to judge a business through a full cycle, a way to compare a company against peers, and something that checks whether the rule behind your buying has worked. Ten years of financials and estimates covers the first two, and costs about $25 to $40 a month from the published tier of the research software market.
Does buy and hold beat active strategies?
Often, and that is precisely why it is the benchmark every backtest here is measured against. AgentTrading compares your rule to holding the identical asset over identical dates with the same costs applied, and stamps UNDERPERFORMED when holding won. A tool that cannot deliver that verdict is not testing your idea, it is selling you one.
How long should you backtest a long-term strategy?
Long enough to include at least two distinct market regimes, which in practice means twenty years or more for an equity rule. A ten-year window ending in 2021 contains one long bull market and will flatter almost any strategy that stays invested. The 2000 to 2002 and 2007 to 2009 drawdowns are where long-term rules actually get tested.
Should dividends be included in a backtest?
Yes, and leaving them out is the most common way a long-horizon backtest ends up wrong. Price-only data materially understates the return of anything dividend-paying, and the gap compounds over decades. Every AgentTrading test uses split and dividend adjusted data with payouts reinvested, so the comparison against buy and hold is total return on both sides.
Is a stock screener the same as a backtest?
No. A screener shows you which companies meet your criteria today, or in some tools what the fundamentals looked like in a past year. A backtest executes a rule across history and produces entries, exits, a drawdown curve and a benchmark comparison. A screen is a rule whether or not you thought of it that way, and it can be tested.
