The strategies behind the cards

Six classic stock-picking strategies, explained

Every ValuJack card comes from one of six published investing strategies. Here is what each one looks for, what the evidence says, and how they differ.

Pick a strategy

Each strategy has its own page: where it comes from, its original rules, what independent research found, the mistakes people make with it, and exactly where ValuJack follows the original and where it doesn't.

How the six differ

CardLooks forPrice viewTypical patience
KINGA long record of rising dividendsReasonableYears
QUEENHigh return on capital and high earnings yieldCheapAbout a year per holding, three to five years for the method
ACECheap companies with improving accountsVery cheapAbout a year
TWOUnloved companies that are financially strongVery cheapTwo to three years
JACKA healthy uptrend near the highs, with growing profitsPrice strength firstWeeks to months, with a strict loss limit
JOKERFast, accelerating earnings growth with price leadershipPrice strength firstWeeks to months, with a strict loss limit

The four value strategies buy what the market currently undervalues and wait for it to notice. The two growth strategies do the opposite: they wait for the market to confirm that something is going right. They tend to do well at different times, which is why ValuJack deals from all six.

What the original strategies don't do, and ValuJack adds

Each original strategy is a filter for one idea. None of them asks the same final questions of every company, so ValuJack does:

  • Is it priced sensibly? Our own fair value model estimates what each company is worth from its reported earnings, with cyclical companies valued over a whole cycle.
  • Is the price still falling? For the value cards, we wait until the price has turned up from its low.
  • What can't the numbers show? The Edge Check, below, reads the reports, filings and news before each card is dealt.

Every difference from the original method is written out on that strategy's page. The process is on the methodology page, and every card ever dealt stays on the card history.

The Edge Check

Every original strategy leaves something to judgement that no screen can measure. The Edge Check is ValuJack's answer: before a card is dealt, an AI research agent reads the company's latest reports, official filings and news, and asks the one question that matters most for its strategy.

CardThe Edge Check question
KINGIs the dividend safe and still growing?
QUEENIs the high return on capital real and lasting?
ACEIs the improvement real and still going?
JACKIs there real news behind the price trend?
JOKERWhat is new, and does it carry the growth?
TWOIs the bad news temporary or permanent?

Checked for every card

  • Insider trades: are the company's own managers buying or selling shares with their own money? Awards, option exercises and routine trades are ignored.
  • Short sellers: are professional investors betting against the company, and is that bet growing?
  • Report wording: has anything changed since last year in the risks, targets, dividend policy, accounting rules or the auditor's report?
  • Customers, suppliers and peers: what have they said about demand since the company's own latest report?
  • Management's record: have they met their own targets, and have the finance chief or the auditor left unexpectedly?
  • The latest report: a clear beat or miss, and has guidance been raised or cut?

What stops a card outright

A profit warning, a takeover bid, a trading suspension, profits not backed by cash, doubt about the company's future or a qualified audit opinion, restated accounts, a large new share issue, a regulator investigating the accounts, or an unanswered fraud allegation from short sellers.

Argue the opposite

Before any verdict, the agent writes down the three strongest reasons the card could fail within the strategy's time frame, and looks for evidence on each.

A stop removes a company; the other signals move companies up or down the order, and the best-placed company that passes is dealt. Open a card's details in the app to see its Edge Check: the question, a short answer, up to three signals, what would break the case, and the date it was checked.

Every point needs a source and a date: the company's own reports, official registers of insider trades and short positions, and exchange news. Forums, social media and analysts' price targets never count. The Edge Check never changes the fair value or the star rating, and never says buy or sell. It is research done by an AI agent under fixed rules, live since 28 October 2026; it can miss things or be wrong.

Questions people ask

Which stock-picking strategy is best?

None wins in every market. Value strategies and momentum strategies tend to do well at different times, and each of the six has had long stretches behind the market. That is the reason for dealing from all six.

What is the ValuJack Edge Check?

A daily research step on top of the six strategies. Before a card is dealt, an AI agent reads the company's latest reports, official filings and news, asks the question that matters most for its strategy, and checks insider trades, short sellers, report wording, peers, management's record and the latest results. It can stop a card or change which company is dealt; it never changes the fair value or says buy or sell.

Are these strategies ValuJack's own inventions?

No. Each is the published work of its author or, for dividends, of S&P's index rules. ValuJack's part is the implementation, and every difference from the original is explained on the strategy's page.
