John Boik: Studying Winners Without Rewriting History

A chart stops at 50.00 resistance. The next page shows it at 90.00 six months later, and the earlier base suddenly looks obvious. John Boik’s historical studies make large stock moves available for close examination. The challenge for the reader is keeping the eventual winner from rewriting what was knowable at 50.00.

Boik wrote Monster Stocks, How Legendary Traders Made Millions and Lessons from the Greatest Stock Traders of All Time. His publisher’s description of Monster Stocks supports the emphasis on studying historical winners. That gives a useful starting point for research. It doesn’t establish the odds of the next similar chart succeeding.

The prices, counts and results below are hypothetical exercises. They’re independent illustrations of how a reader might examine historical examples, rather than trading rules or measured results attributed to Boik.

John Boik and the chart with its right edge covered

Suppose a stock has spent eight weeks between 44.00 and 50.00. Its latest close is 49.60. With future bars hidden, an analyst can record the range, its duration and the distance to resistance. A description such as “ready to double” already reaches beyond the available record.

I would keep 49.60 in the study note because it preserves the actual decision point. Replacing it with an ideal entry at 50.00 after seeing the subsequent advance quietly changes the question. The first note asks what could be inferred before the breakout; the second assumes access to a trade that may have filled differently.

A useful replay reveals one session at a time. If the next bar reaches 50.30 and closes at 49.70, an intraday trigger has occurred while a closing trigger hasn’t. Both definitions are possible research choices. Their results can’t be mixed after the outcome becomes visible.

The site’s market structure guide supplies language for swings and ranges. A chart library becomes more informative when those terms have recorded definitions. Otherwise a winning chart receives generous interpretation while an awkward failure is dismissed as an imperfect pattern.

Fifty winners leave the denominator unanswered

Imagine finding the same narrow base in 40 of 50 stocks that later doubled. That’s 80% of the selected winners. It says nothing by itself about how often stocks with the base doubled. The sample began with the result that the researcher hoped to explain.

Now imagine a separate scan identifying 400 stocks with that base before their outcomes were known. If 40 subsequently doubled, the proportion is 10%. Both calculations can be true simultaneously. They answer different questions, and confusing them can make a common chart feature seem unusually predictive.

This is a general limitation of choosing examples by eventual success. It isn’t a claim that Boik omitted failures from his research. The practical task for a reader is to establish what the selection process permits them to conclude.

Even the second sample needs a time limit. Doubling within six months differs from doubling at any point over ten years. Delisted stocks, changed symbols and missing data can also alter the denominator. A spreadsheet of surviving names may be convenient while excluding the very outcomes needed to assess risk.

Measure the base before naming its quality

A range from 44.00 to 50.00 is 12% deep when measured from its high. A later range from 48.00 to 50.00 is 4% deep on the same basis. Recording those figures makes contraction visible without relying on adjectives such as orderly or powerful.

The calculation doesn’t reveal why the range narrowed. A quiet period could reflect reduced participation, balanced demand and supply, or a temporary pause before news. It doesn’t identify institutional accumulation or prove that potential supply has disappeared.

Volume can be recorded alongside the price measurements. Suppose the first four weeks average one million shares daily and the last four average 650,000. The latter average is 35% lower. An analyst might then investigate how often comparable contractions precede continued advances, sideways movement or declines.

That comparison needs consistent observations. Holiday sessions, incomplete trading days and changes to the share count can complicate raw totals. The Volume Rate of Change discussion offers related measurement language, but adding an indicator can’t repair a sample chosen only from successful outcomes.

The entry price changes the historical lesson

A stock that eventually reaches 90.00 may still create a difficult trade. In a hypothetical path, it breaks 50.00, trades at 53.00, falls to 46.00 and only then begins the long advance. A chart ending at 90.00 can make the interruption seem harmless.

For a hypothetical entry at 50.50 with an intended exit at 48.00, the initial distance is 2.50. A fill at 48.00 would end that particular trade before the later recovery. Recording the full advance as its return would assume a holding decision that contradicts the stated exit.

I separate the move from the trade at precisely that 48.00 level. The stock’s eventual success doesn’t erase the failed first attempt. A second entry would need its own date, conditions and costs rather than an invisible reset in the original record.

The William O’Neil profile is a related reading point for growth-stock and chart study. Comparing approaches is useful when the comparison preserves each method’s entry and exit assumptions. Combining the most attractive parts of several finished examples creates an exercise nobody could have followed.

A companion set of failed and unfinished cases

A research notebook might hold three groups: completed advances, failed attempts and unresolved setups. The third group matters because a current chart is always unfinished. An example that spends another twelve weeks inside its base hasn’t yet supplied the dramatic ending that a published case study tends to have.

For a hypothetical comparison, define a breakout as the first close above the previous eight-week high, then observe the next twenty sessions. Record the closing return, deepest adverse move and whether the planned exit was touched. The twenty-session horizon is an illustrative choice, not a threshold from Boik.

The same fields belong in every row. A losing example shouldn’t acquire a new exclusion rule simply because its volume looked slightly awkward. If a proposed volume filter is worth investigating, it can become a separately named test applied across the whole set.

Unresolved cases also reveal the cost of waiting. Capital tied up in a flat position, repeated spread costs on re-entries and the amount of monitoring required may all matter. A collection that records only the largest eventual advances leaves those practical demands difficult to see.

Different decades need comparable information

Suppose a historical chart marks a 20.00 breakout and today’s adjusted series shows the same point at 5.00 after a later split. Those levels may describe the same economic event. Using the old chart’s 20.00 entry against the adjusted series would produce meaningless arithmetic.

A study can retain the data convention beside every example: split treatment, dividend treatment, volume adjustment and observation frequency. Weekly bars also hide the order of events within the week. A weekly high above a trigger and low below an exit don’t establish which came first.

There are comparable problems with fundamentals. A strong earnings figure reported after the breakout wasn’t available beforehand. Using the later result to label an earlier setup as fundamentally confirmed introduces information from the future.

Historical examples still offer rich detail. Their value increases when the reader can distinguish the chart’s visible record from later explanations. A precise statement of what remains unknown is more useful than forcing every winner into the same tidy sequence.

One further check concerns the benchmark available during the same holding period. If a hypothetical stock advances 20% while its comparison index advances 25%, the stock has risen substantially while lagging that reference. The choice of benchmark deserves a reason recorded before evaluating the result. A historical winner selected for its absolute gain may answer a different question from a study seeking outperformance. Keeping both measures prevents the word winner from quietly changing meaning between examples.

Books for studying John Boik

These three paperbacks are by John Boik. They offer historical reading at different scopes. A reader comparing a 50.00 breakout with a later 90.00 price can use the books to frame questions, while keeping the separate trade simulation and comparison sample described above. The 2023 paperback of Monster Stocks is labelled explicitly.

Leave the next page closed a little longer

The most revealing note in a historical chart exercise may be the one made at 49.60, before the final outcome is visible. It preserves uncertainty that disappears from a finished winner. Keeping that note beside the later chart shows which observations were available and which arrived with hindsight.

Boik’s subject offers plenty to study. The reader’s added discipline is to carry the failed 48.00 exit and the unfinished base into the same notebook as the spectacular advance.
