The IBD Power Trend is one of the most precisely defined concepts in momentum trading — a named, rule-based market condition developed by Investor's Business Daily that signals when momentum traders should operate at maximum aggression. Triggered when three specific conditions around the 21-day and 50-day moving averages align simultaneously, it was developed by Mike Webster, Head of Market Strategy at IBD, through a systematic historical study of the Nasdaq going back to 1949. Fewer than 200 IBD Power Trends have been identified across the full history of the index. Each one has coincided with one of the great bull market phases of the modern era.
For ASX momentum traders, understanding what triggers a Power Trend — and what it historically implies for trend duration and position sizing — is one of the most practical applications of IBD methodology available in the Australian market context.
Traders who are new to the 50-day moving average as a momentum filter should first read The 50-Day Moving Average Trading System: How One Line Captures 70–80% of Major ASX Moves — it establishes the foundational mechanics this article builds on. For the broader Minervini and IBD methodology context, What is Mark Minervini's Trading Strategy? The Complete SEPA & VCP Guide covers the full framework.
What Is the IBD Power Trend and Who Created It?
The IBD Power Trend was developed by Mike Webster, Head of Market Strategy at Investor's Business Daily, in collaboration with Charles Harris and Justin Nielsen. It emerged from a project called Market School — IBD's attempt to translate the intuitive market-reading of founder Bill O'Neil into a set of black-and-white, mechanical rules that could be applied consistently by any trader.
Webster has described the methodology in detail. The team printed off the full history of the Nasdaq on daily charts, colour-coded each period by market condition — periods when a trader would want to be fully invested versus periods when the trader should be in cash — and worked backwards to identify what characteristics all the great bull trends had in common at their very beginning. The Power Trend was the result: a consistent set of moving average conditions that appeared at the outset of every major sustained advance in the Nasdaq's recorded history.
According to Webster, fewer than 200 Power Trends have been identified across the full history of the Nasdaq. Some lasted only a few weeks. Others ran for close to two years. What they share is rarity — and the significance that rarity implies. Each confirmed Power Trend has occurred within one of the defining bull market phases of the past century, from the post-war expansion of the late 1940s and 1950s through to the recovery from the 2008 financial crisis.
The Power Trend is not a buy signal for individual stocks. It is a market condition diagnostic — a reading of the broader environment that tells momentum traders whether the institutional tailwind behind their individual setups is operating at its maximum historical strength.
For a comparison of how IBD's systematic approach relates to other momentum methodologies, Mark Minervini vs William O'Neil vs Warren Buffett: Trading Style Comparison covers each practitioner's framework in full.
What Are the Three Conditions That Trigger the IBD Power Trend?
The Power Trend is defined by three sequential conditions. All three must be present simultaneously, and the signal is confirmed only on an up day — IBD's principle being that market exposure is never increased during a down session.
Condition One — Daily low above the 21-day exponential moving average for at least 10 consecutive days
The daily low of the market — not the close, the low — must trade above the 21-day exponential moving average for a minimum of ten consecutive sessions. The use of the daily low rather than the daily close is deliberate: it is a stricter test. A market that closes above the 21-day but trades below it intraday has shown weakness at the line, even if it recovers by the close. Ten consecutive sessions with the daily low above the 21-day confirms that the 21-day is functioning as genuine institutional support — not merely a line the market oscillates around.
Condition Two — The 21-day exponential moving average above the 50-day moving average for at least 5 days
The 21-day exponential moving average must have crossed above the 50-day moving average and held above it for a minimum of five days. This confirms that shorter-term momentum has rotated above the medium-term trend — a structural shift rather than a temporary spike. The 21-day crossing above the 50-day is one of the most consistent early signals that a new institutional uptrend has established itself with sufficient force to be sustained.
Condition Three — The 50-day moving average must be in a rising uptrend
This is the most demanding condition and the one that requires the most patience to confirm. The 50-day moving average must itself be pointing upward — not flat, not declining. Webster noted that including this condition reduced the headline performance of the Power Trend indicator in backtesting, because there are periods where the first two conditions are met but the 50-day is still turning from a decline. Those periods would have shown reasonable returns. But including the rising 50-day as a requirement also reduced the failure rate significantly — because when momentum breaks out through a declining 50-day, the odds of that breakout holding are materially lower than when it breaks through a rising one. As Webster put it, the declining 50-day means "the odds are stacked against you."
In Gary Glover's anecdotal observation across his trading career, the patience required for the third condition to be met is often the defining test for momentum traders. His observation from the 21 April 2026 session: "the average power trend's about 77 days" — and the wait for the 50-day to turn from flat or declining to rising can take weeks after the first two conditions have been satisfied.
When all three conditions are met and confirmed on an up day, Webster puts the implication directly: "once that power trend turns on you say I'm in something special." The historical record supports that characterisation — each confirmed Power Trend has been followed by trend strength that extended considerably longer than most market participants expected at the time it was triggered.
Gary Glover's observation from the 21 April 2026 session reinforces this: that real strength out of the gate in these conditions tends to lead to the trend remaining strong for an extended period — not a brief burst followed by reversal, but a sustained advance that rewards traders who stay engaged rather than reducing exposure as the market rises.
The rule-based structure of the Power Trend sits naturally alongside the B-wave trade checklist that FMP uses as a companion entry tool — both rely on the 50-day moving average as the primary structural integrity filter. The process-over-opinion discipline that underpins how Gary applies these rules systematically is covered in Why Gary Glover's Trading Philosophy Emphasises Process Over Market Opinions.
What Does the Historical Record Show About IBD Power Trend Duration and Strength?
The historical Power Trend examples documented by Webster span more than six decades of Nasdaq history. Each one aligns with a period most momentum traders will recognise as exceptional — and in each case, the strength of the initial move proved to be a feature of the trend, not a warning that it was overextended.
The earliest documented example began on 26 July 1949 and ran until 29 June 1950 — almost a full year, coinciding with the early stages of the great post-war bull market. The following example ran from October 1953 through to August 1955 — close to two years, covering the heart of the secular bull that IBD has studied extensively as a precedent model for identifying the kind of long-cycle market environment where momentum strategies produce their strongest results.
The 1958–1959 Power Trend coincided with the period Nicolas Darvas made his famous moves in the market, documented in How I Made $2,000,000 in the Stock Market — a period where a small number of leading stocks advanced hundreds of percent in compressed timeframes. The 1982–1983 example captured the opening phase of the great bull market that ran from 1982 to 2000 — the period during which IBD was founded and O'Neil's methodology was first publicly documented and tested in live markets.
More recently, the April 2003 Power Trend ran through to February 2004, covering the early phase of the recovery from the dot-com bear market — a period characterised by extreme scepticism about whether the recovery was real, and where traders who trusted the technical conditions were rewarded for holding through the noise. The April 2009 Power Trend ran from the follow-through day that ended the financial crisis bear market through to February 2010.
In each case, the common thread is that the majority of market participants expected the advance to stall earlier than it did. The traders who reduced exposure on the grounds that "it has already gone up too much" repeatedly gave up the majority of the available gains. The Power Trend, as a defined condition, provides the framework for overriding that intuition and staying engaged until the conditions that triggered the signal are actually reversed.
For the broader market cycle context within which Power Trends occur, Midterm Election Year Stock Market Cycles: The Complete Guide for ASX Traders in 2026 provides the cyclical framework. The sector rotation patterns that typically emerge during these high-conviction market phases are explored in From Energy to Growth: The 3-Signal Framework Gary Glover Uses to Identify the Next ASX Market Leaders.
How Do ASX Momentum Traders Apply the IBD Power Trend?
The practical implication of a confirmed Power Trend is a shift in default position sizing and market engagement. In normal market conditions, momentum traders calibrate exposure carefully — fewer positions, smaller sizes, tighter management of open profits. When a Power Trend is confirmed, the historical evidence supports a deliberate shift toward maximum engagement: fuller position sizing, a higher number of concurrent positions, and greater tolerance for holding through normal volatility without reducing exposure.
The 50-day moving average is the structural foundation of this shift. Gary Glover's anecdotal observation across his trading career is that stocks purchased above the 50-day moving average carry approximately double the forward return probability of stocks purchased below it — a practitioner observation he has verified year after year by reviewing the historical behaviour of Australia's highest-performing growth names. The Power Trend is the market-level confirmation that this individual-stock edge is operating across the entire institutional landscape simultaneously.
William O'Neil's research across thousands of historical breakout events reinforces this at the statistical level: breakouts occurring on volume at least 40% above the 50-day average volume succeed at 73% compared to 48% for low-volume breakouts (How to Make Money in Stocks, 2009, McGraw-Hill). A Power Trend environment is precisely the condition under which those high-volume, high-conviction breakouts cluster.
For ASX momentum traders, the practical monitoring process involves tracking whether the three Power Trend conditions are being met across the major indices — particularly the Nasdaq, which is the index the indicator was calibrated against — and whether ASX growth stocks are confirming the same structural alignment domestically. When multiple ASX growth names break above their 50-day moving averages within a concentrated period, Gary Glover's anecdotal observation is that this clustering is a market-level confirmation signal. It is qualitatively different from a single isolated breakout — it reflects a broad shift in institutional positioning across the growth sector.
The FMP Momentum Profile Filter System provides the systematic tool for monitoring the percentage of ASX stocks above their 50-day moving averages — the breadth reading that captures whether ASX market conditions are generating the kind of broad participation that historically accompanies Power Trend environments. For the specific VCP patterns that tend to emerge most frequently when these conditions are in place, How to Identify VCP Patterns on ASX Stocks: The 3-Stage Australian Market Adaptation covers the identification process in full.
Gary Glover's 21 April 2026 session identified the then-current market environment as exhibiting the clustering of ASX growth stocks breaking above their 50-day moving averages — one of the early confirming signals that the structural conditions supporting a Power Trend were forming. The observations from that session are explored further in 7 Momentum Trading Lessons from Gary Glover's ASX Watchlist Review.
How Does Historical Range Squaring Help Identify Price Targets During a Power Trend?
Knowing that a Power Trend is active tells a momentum trader to be engaged and aggressive. The next practical question is how far the move may run — and where the most significant resistance zones are likely to appear along the way. Gary Glover's range squaring methodology, developed across his trading career, provides a structured and historically-grounded approach to answering that question.
The process involves taking a significant historical bear market — the GFC decline, the Covid selloff — and squaring the range of that decline using percentage and Fibonacci extensions projected forward from the low. Each extension level — 161%, 200%, 300%, 450%, 600%, 700% — has functioned as a resistance zone in the S&P 500's post-GFC recovery. Gary Glover's anecdotal observation is that each level has been tested, met resistance, and ultimately broken before the next level became the target. The pattern has repeated across six successive extension levels over more than fifteen years of the post-GFC recovery.
The practical application for a trader in a confirmed Power Trend: the Power Trend answers whether to be in the market. Range squaring answers how far to let the position run before the next structural test. A trader who knows both that the Power Trend is confirmed and that the next resistance zone lies at a specific extension level has two complementary pieces of information working in the same direction — one instructing engagement, one informing expectation management.
For the trend line analysis that complements range squaring in identifying when major moves are approaching exhaustion, From Gold Rush to Crash: Why 6–7 Ascending Trend Lines Signal 50% Corrections on ASX covers the pattern in detail. The companion piece on accelerating trend line breaks — How to Identify When Accelerating Trend Lines Break: The 98% Pattern That Signals 50% Corrections on ASX Stocks — addresses what happens at the end of extended Power Trend-style moves when the advance begins to accelerate beyond sustainable rates.
What Is Bullish Spacing and Why Does It Confirm a Breakout?
Bullish spacing is a specific price action condition where an index or stock closes not merely above a prior resistance level but leaves a visible gap above it — the close is sufficiently far above the prior high that the level has been cleared with force rather than marginal effort. Gary Glover's anecdotal observation is that this condition, when it appears on an index chart following a period of consolidation near a prior high, has historically been associated with sustained follow-through moves rather than false breakouts or near-term reversals.
The distinction matters because not all closes above a prior high carry the same informational weight. A marginal close — where price just edges above the prior level — can be reversed in the following session without significant supply being absorbed. A close that leaves spacing above the prior level indicates that demand was sufficient to overwhelm supply at that level without hesitation. In the context of a confirmed Power Trend, bullish spacing on an index provides additional confirmation that the move is institutional in character. For traders monitoring Cup and Handle patterns on individual ASX stocks during these periods, bullish spacing on the breakout day applies the same principle at the stock level — it distinguishes a high-conviction institutional break from a tentative close above resistance.
Key Takeaways
The IBD Power Trend is a rare, rule-based market condition — fewer than 200 confirmed instances in the full history of the Nasdaq — that signals when the structural environment for momentum trading is operating at its historical maximum. Its three conditions are precise, sequential, and verifiable. Its historical record across six decades of documented examples is consistent: each Power Trend has coincided with one of the great bull market phases of the modern era, and the initial strength of each move has extended further than most participants anticipated at the time.
For ASX momentum traders, the Power Trend is not a standalone indicator. It functions as the market-level confirmation that the individual-stock edges — the 50-day moving average filter, the VCP pattern, the sector rotation signals — are all operating within the most favourable structural environment in the historical record. When those individual signals align during a confirmed Power Trend, the evidence supports maximum engagement over caution.

Frequently Asked Questions
What is the IBD Power Trend?
The IBD Power Trend is a named market condition indicator developed by Mike Webster, Head of Market Strategy at Investor's Business Daily, that identifies rare periods when momentum traders should operate at maximum aggression. It is triggered by three simultaneous conditions involving the 21-day exponential moving average and the 50-day moving average. Fewer than 200 Power Trends have been identified in the full history of the Nasdaq.
What are the three conditions for the IBD Power Trend?
The three conditions are: (1) the daily low of the market must hold above the 21-day exponential moving average for at least ten consecutive days; (2) the 21-day exponential moving average must have crossed above and held above the 50-day moving average for at least five days; (3) the 50-day moving average must itself be in a rising uptrend — not flat or declining. All three must be confirmed simultaneously, on an up day.
How many Power Trends have occurred in history?
According to Mike Webster's research at IBD, fewer than 200 Power Trends have occurred across the full recorded history of the Nasdaq. Some lasted only a few weeks. The longest ran for close to two years. The rarity of the condition is central to its significance — each confirmed Power Trend has coincided with one of the defining bull market phases of the past century.
How long does a Power Trend typically last?
Gary Glover's anecdotal observation across his trading career is that the average Power Trend runs approximately 77 days. Webster's historical research shows considerable variation — from a few weeks to close to two years for the longest examples in the 1940s and 1950s. The initial strength of the move has historically been a feature rather than a warning: the early aggressiveness of a Power Trend advance has tended to persist rather than revert.
How does the IBD Power Trend differ from a standard market uptrend?
A standard market uptrend is a general directional condition — price is making higher highs and higher lows. The Power Trend is a precisely defined institutional condition with three specific, simultaneously-met criteria. The distinction is between observing that the market is trending upward and confirming that the structural moving average alignment historically associated with the longest and strongest bull phases is in place. Not all uptrends are Power Trends — fewer than 200 periods in the Nasdaq's full history have qualified.
What is bullish spacing in technical analysis?
Bullish spacing is when an index or stock closes not merely above a prior resistance level but leaves a visible gap above it — the close is far enough above the prior high that the resistance level has been cleared with force. Gary Glover's anecdotal observation is that this condition is historically associated with sustained follow-through rather than false breakouts, and carries materially more informational weight than a marginal close above resistance.
How do ASX traders know when an IBD Power Trend has ended?
The Power Trend ends when the 21-day exponential moving average crosses back below the 50-day moving average — the same crossover that triggered the condition, now reversed. Webster's research identified this as the clean mechanical off-signal: when the 21-day rolls through the 50-day to the downside, the special condition is over. At that point, the default shifts from maximum aggression back to normal market conditions and standard exposure management.
