Works for US-listed companies that file 10-K reports with the SEC.

How Stock Checker works

It reads each company's official reports filed with the US SEC (up to 10 years), adds today's price, and runs the same checks every time. Nothing is hand-picked, and every number shows how it was judged.

The five checks

Shariah screenBusiness activity plus the AAOIFI-style ratios: interest-bearing debt under 30% of market value, cash and interest-bearing securities under 30%, interest income under 5% of revenue. A failure means an automatic Avoid.
Quality (0-100)Mostly return on invested capital and how consistent it is, plus margins, cash conversion, profit history, share dilution and stock-based pay.
Balance sheet (0-100)Net debt versus earnings, interest coverage, short-term liquidity, debt versus equity, and how fast free cash flow could repay all debt.
Growth (0-100)Revenue, earnings-per-share and free-cash-flow-per-share growth over about 5 years, how consistent it was, and whether it is speeding up or slowing down.
ValuationA fair value from future owner cash flow (free cash flow minus stock-based pay), checked against the stock's own past valuation and its PEG ratio.

How the verdict is decided

Strong buy candidateHigh quality, healthy balance sheet, priced below fair value, no warning signs, high confidence.
Buy candidateHigh quality at a fair price (or cheap with a caution).
Possible bargainHigh quality and very cheap, but the price assumes a sharp slowdown. Either an opportunity or a trap: research first.
WatchlistHigh quality, but the price is too high. A "buy below" price is shown.
Worth a closer look / PassAverage business: cheap is worth researching, otherwise pass.
AvoidFails the Shariah screen, weak returns, or a risky balance sheet.
SpeculativeLosing money and burning cash, so fundamentals cannot value it.

The fair value, in plain words

The tool projects 10 years of owner cash flow. Revenue grows at a blend of the company's track record (the lower of its 5-year and 3-year growth rates, so one unusual year like 2020 can't inflate it) and its recent growth (capped at 20% a year), then slows to 2.5%. Cash margins stay at their typical recent level. Future cash is discounted at 8% for strong, large companies, 9% for typical ones and 10% for weaker or small ones. The bear and bull cases change growth and margins. It also works backwards: what growth does today's price assume? That one number often teaches more than the fair value itself.

Limits to know: it assumes today's cash margins continue, so companies spending heavily now to grow later can look expensive, and hypergrowth companies are capped at 20% growth.

The Technical tab

A second view of the same stock: the chart. It reads about five years of daily prices and checks the trend (21-day EMA, 50-day and 200-day averages), momentum (RSI, MACD), volume, and support and resistance levels from past swing highs and lows. It then looks for one of a few long-only setups (a pullback to the averages in an uptrend, a breakout on strong volume, an oversold reversal, a bounce at range support) and builds a swing plan: entry trigger, stop loss, two targets and an exit plan. A calculator shows what that means in dollars, and the most you should invest so one loss costs at most 1% of your portfolio.

The long-term plan on the Fundamental tab is different: buy and trim levels from the fair value, and "sell if" rules based on the business, with no stop loss. The best entries have both tabs on their side. No set of indicators wins most of the time, so judge any plan over many trades.

Shortlist, watchlist and track record

The Shortlist screens every company each morning: swing buy signals, quality businesses below fair value, stocks near their buy price, market leaders and dividend payers, with halal, sector, size and earnings filters. The Watchlist follows the companies you star (saved on your device only) and flags what changed: the verdict, halal status, new signals, earnings dates, and your own stop and target levels. The Record shows how the exact swing rules did on five years of prices, and a live log of every signal since the site started.

Dividends and purification

For dividend payers, the Fundamental tab shows the yield, how much of profit is paid out, and the history, plus a calculator for the impure share to give to charity. It is estimated from interest income; if Zoya or Musaffa show a higher figure, use theirs.

What it cannot do

  • See the future. Past numbers can't show a new competitor, a technology shift like AI, or a management mistake. The Business check section turns those questions into evidence, and the research button gets Claude to look at the latest news for you.
  • Judge banks, insurers, REITs or foreign companies (20-F filers) properly. Those get a warning or are not supported.
  • Replace the official halal screeners. Confirm every stock on Zoya or Musaffa before buying.

Using a verdict sensibly

  • Treat "buy candidate" as "worth owning", not "buy everything now". Buying in a few steps lowers the risk of bad timing.
  • Spread your money: as a rule of thumb, keep any single stock below about 10% of your portfolio.
  • Re-check after each quarterly report. Verdicts change when the numbers or the price change.
