Martin Pring on Market Momentum — Pring: COMPLETE

Most technical books are toolboxes: one chapter on trend, one on support, one on indicators, one on patterns. Pring did the opposite in 1993: he took ONE tool — momentum — and wrote an entire book about it. Why? Because momentum is not one indicator among others; it is a different QUESTION. All charting tools fundamentally answer two questions: where is the price, and where are the levels? The momentum indicator asks the third: how fast is the price moving — and is the pace about to change? Pring's claim, on which the whole book rests: a movement loses speed BEFORE it changes direction, like a car slowing before a turn — and thus the momentum series turns ahead of the price.

That is the whole course's and book's reason for existing in one sentence: momentum is the price's earliest witness.

The differentiation in the lab, openly declared, from the very first chapter. Murphy's The Visual Investor (its own course in the catalog) is the book of the GRAPH: trend, support, volume, rotation, intermarket — learning to SEE. Elder's Come Into My Trading Room (its own course) is the book of the ROOM: the three Ms, systems, psychology, the 2- and 6-percent rules — learning DISCIPLINE.

Pring's book is the book of the CONCEPT: speed, time, momentum, in three time dimensions — learning to MEASURE pace. The consequence for the ecosystem is concrete: where the Murphy course finishes momentum in a single chapter, this course spends fifteen chapters inside the speedometer — including the indicator that carries Pring's name in the world's chart programs: KST.

And a line of honesty right in the opening chapter, which the controversy chapter (14) then owns in full: the book came out in 1993 — the same year Jegadeesh and Titman published Returns to Buying Winners and Selling Losers in the Journal of Finance, the foundational evidence of the momentum anomaly. Pring could not know that; yet his practical craft, decades old when the book was printed, suddenly stood on academic ground.

It is a unique position in the book master: here the TA crowd does not need to defend itself against the academy — the academy confirmed. But the same research also delivers the warning: momentum crashes. Both halves belong from chapter one; the course is not a tribute serial but an examination.

AKM1 BRIDGE · V01 Revenue growth — the fundamentals' OWN speed gauge. The formula in AKM1 is (Revenue this year − Revenue last year) / Revenue last year — mathematically a rate of change, the same quotient chapter 4 teaches you to compute on the price. V01 is the fundamental's momentum line; the course teaches you to read it the way Pring reads a ROC curve: not just the level but the SWINGS.

AK1TS LINE: the momentum lines — the engine measures 5/63/252 days per horizon; Pring's book is the theory behind lines that already exist in the lab's code.

The physics, as Pring himself uses it: price is POSITION — where the car is on the road. Momentum is SPEED — how fast it is moving. And the change in momentum is ACCELERATION — throttle or brake. Of the three, only position is visible directly on the price chart; speed must be computed (chapter 4), but it contains information that position lacks: a car at 110 that has slowed from 130 is a different story than a car at 110 accelerating from 90 — the same reading on the speedometer, a completely different next minute.

A price of 100 — as this course keeps insisting — can be a top or a base; speed decides which. That is why the momentum series deserves its own window next to the price.

Momentum in the physics sense — p = mass × velocity — is the course's third concept and is tied to volume in chapter 11. On the market, MASS is participation: how many actors, how much capital, how many stocks change owners. A price move on enormous volume has mass — it is hard to stop, its inertia is great. The same price move on thin volume is nearly massless: easy to turn, worth little as evidence.

Pring does not use the term himself — but his whole body of work on volume confirmation rests on the intuition: speed without mass is not momentum. Note that AKM1's V12 Revenue stability is the fundamentals' measure of mass — book canon entry bk-060 already links them: stable, predictable revenue is inertia in the business, and inertia is what makes fundamental trends durable enough to be measured.

And the practical core, to which the course returns in every tool chapter: the three-stage sequence of the turn. One — momentum turns (speed diminishes; the car brakes but still rolls forward). Two — the price stops and moves sideways (the rally no longer lives but the resistance is not enough for a turn; a base building or top formation takes shape). Three — the price turns (position finally follows speed). The consequence for trading is the book's most important division of labor, straight from the book canon lessons: MOMENTUM FOR TIMING, THE TREND FOR DIRECTION — never the other way around.

Momentum says WHEN the force is waning; the trend (MA, trendlines) says which side to play. Whoever buys on low momentum without trend support behind it buys a falling blade; whoever sells on high momentum in a strong uptrend sells strength.

AKM1 BRIDGE · V12 Revenue stability — the book canon's ak variable for this book: the mass and inertia of the fundamentals. A company with stable revenue (high V12) has a fundamental movement with mass — it accelerates slowly and decelerates slowly, which makes momentum reading meaningful on quarterly series. A company with wildly swinging revenue has fundamentally zero mass: every momentum reading is noise.

AK1TS LINE: the Trend dimension × five horizons — the engine reads speed (momentum 5/63/252) and regime (MA50/MA200) as two different questions, exactly as Pring reads momentum and trend as two different tools.
