The Investment Strike Zone adapts Ted Williams's hitting discipline to markets. An investor first defines the kinds of assets, patterns, time horizons, and risk structures that fit their own abilities. Opportunities outside that zone are deliberately ignored, even when they appear attractive to someone else. Inside the zone, the investor studies repeated historical examples until common tendencies become recognizable, then waits for current conditions to resemble a practiced setup. This selectivity does not guarantee a profitable result; it improves the odds that the investor understands the opportunity and can manage it consistently. The framework also separates individual style from universal prediction: one person may appropriately pass on a stock that perfectly fits another person's process. Performance comes from choosing good pitches for your swing, not swinging at everything.
Origin
John Roque drew the model from Ted Williams's The Science of Hitting and Rogers Hornsby's rule that a hitter must get a good ball to hit.
Core principles
- 01A valid opportunity can still be wrong for a particular investor
- 02Selectivity raises the probability of executing well
- 03Repeated exposure builds pattern recognition within a defined style
- 04Passing on unsuitable opportunities is part of disciplined performance
How to run it
- 1
Define your style
State the markets, holding periods, patterns, and risk characteristics in which you have demonstrable competence.
Pro tip Base the definition on reviewed decisions rather than an aspirational identity.
Watch out A style that includes nearly every opportunity is not a useful filter.
- 2
Draw the strike zone
Translate the style into observable entry requirements and explicit disqualifiers.
Pro tip Use a short checklist that can be applied before every decision.
Watch out Do not move the boundaries simply because a popular asset is rallying.
- 3
Study repeated pitches
Review many historical examples to learn what usually follows when your preferred setup appears.
Pro tip Include failed examples so pattern recognition does not become confirmation bias.
Watch out Visual familiarity alone is not proof of a stable edge.
- 4
Wait without forcing action
Reject opportunities that do not satisfy the defined conditions and preserve attention and capital for better fits.
Pro tip Keep a pass log to reinforce that disciplined inaction is a valid decision.
Watch out Boredom and fear of missing out commonly cause investors to swing outside the zone.
- 5
Act on a suitable pitch
When the required conditions appear, execute according to the predetermined position and risk plan.
Pro tip Decide position size before emotions intensify.
Watch out A good setup can still lose, so never confuse fit with certainty.
- 6
Review the decision
Assess whether the opportunity truly fit the strike zone and whether execution followed the process, independently of the outcome.
Pro tip Update the zone only after a meaningful sample of decisions.
Watch out Do not redefine the framework after every win or loss.
In the wild
A long-term trend investor sees a volatile small-cap stock surge after a news announcement. The move is exciting, but the asset lacks the liquidity, history, and stable trend required by the investor's strike zone. The investor passes and waits for a liquid large-cap trend with a defined invalidation level.
→ Capital and attention remain available for a setup the investor is equipped to manage.
After reviewing hundreds of charts, an analyst recognizes a recurring continuation pattern in a sector already showing relative strength. The setup matches the analyst's preferred horizon and risk rules, so the analyst enters without needing to chase an unfamiliar tactic.
→ The decision is grounded in repeated observation and a consistent personal process.
Common mistakes
Copying another investor's zone
A setup that matches someone else's temperament, time horizon, or expertise may be inappropriate for you.
Swinging from fear of missing out
Popularity and rapid price movement do not make an opportunity compatible with a defined process.
Judging process by one outcome
One profitable off-style trade or one losing in-zone trade does not establish whether the decision rule works.
Is it for you?
Best for
It is best for investors who encounter too many possible trades and need a disciplined selection rule.
Not ideal for
It is not ideal for mandates that require continuous broad-market exposure regardless of setup quality.
From the transcript
“you have to hit according to your style and not swing its stocks that are out of your strike zone.”
“And I think that increases your chance of winning.”
“What's the tendency of a stock to do something after it looks like it looks now?”
