Active vs Passive in Bull Markets
When markets climb broadly, the active manager's edge tends to evaporate. Cash drag, missed leaders, and a few mega-caps doing the heavy lifting all favor the index.
Don't have time? Here's what you need to know:
- 1Broad bull markets reward staying fully invested, which structurally favors index funds over active ones.
- 2Cash drag, underweighting mega-cap leaders, and a 0.5-1.0% fee all pull active funds behind in rallies.
- 3When a few giant companies drive the index's gain, being underweight them is nearly fatal for a stock-picker.
- 4Active has slightly more room in small-caps and emerging markets, but most still lag over a full cycle.
The Comforting Myth About Bull Markets
A familiar pitch holds that active managers earn their keep in rising markets by spotting the winners early and overweighting them. It sounds plausible, and in any given year a handful of managers will indeed do exactly that. But across the full field and across full cycles, broad bull markets have tended to be where active management struggles most, not least, because a rising tide that lifts almost everything rewards the investor who simply owns everything.
The intuition that picking should pay off in a bull market overlooks how those bulls are usually built. When the gains are broad and led by the largest companies, the index already owns those leaders at full weight. A stock-picker has to be both right and concentrated to beat a benchmark that is effortlessly capturing the same rally.
Why Active Tends to Lag in Rallies
Three forces work against active funds when markets climb. First, cash drag: active funds typically hold a slice of cash for redemptions and flexibility, and in a strong up year that uninvested cash is a direct anchor on returns, while an index fund stays essentially fully invested. Second, concentration: many recent bull markets have been driven by a small group of mega-cap leaders, and a manager who is underweight those names, as risk rules often require, mechanically falls behind.
Third, the fee never sleeps. Even a manager who matches the index gross-of-fees hands back 0.5-1.0% a year, so in a good year they have to be better than the market just to tie it net of costs. Add it up and the rising-market scoreboard usually reads the same as every other period: the expense ratio plus cash plus underweighting the leaders, all subtracted from the manager's score.
| Factor in a bull market | Index fund | Typical active fund |
|---|---|---|
| Cash held | ~0% (fully invested) | Often 1-5% cash drag |
| Mega-cap leaders | Held at full index weight | Often underweight on risk limits |
| Annual fee | ~0.03% | ~0.5-1.0% |
| Net effect in a broad rally | Captures the rally | Tends to lag after costs |
Tip: In a year when a few giant companies drive most of the index's gain, being underweight them is nearly fatal for an active manager. The index just holds them and rides.
The Narrow Window Where Active Can Shine
There is a thin slice of bull markets where stock-picking has more room: broad-based rallies in less efficient corners such as small-caps or emerging markets, where the index is not dominated by a few mega-caps and mispricings are larger. In those segments a skilled manager occasionally adds value even while the broad market climbs. But even there, the majority of active funds still lag over a full cycle, and identifying the winners in advance remains the unsolved problem.
For the core large-cap U.S. exposure most investors hold, the honest conclusion is that bull markets are not the active manager's friend. Staying fully invested in a low-cost fund like VOO or VTI captures the upside without the cash drag, the underweighting, or the fee, which is why indexing tends to win the rally as decisively as it wins everything else.
Important: Don't assume your active fund will 'capture more upside' in the next bull run. Historically the average active fund captured less, after cash drag and fees, not more.

How to Position for the Next Bull Market
The lesson is not to time the cycle, which is its own losing game, but to own the market in a way that captures rallies cheaply and automatically. A broad fund held through both good years and bad lets you participate fully in every bull market without having to predict when one starts. Trying to switch into active funds 'for the upside' just before a rally assumes a forecasting skill that the data says almost no one reliably has.
Pair full market exposure with steady contributions through dollar-cost averaging and you remove the temptation to sit in cash waiting for a clearer signal that never comes. The investors who benefit most from bull markets are usually the ones who were already fully invested and simply stayed the course, not the ones who tried to outguess the turn.
Tip: You can't know when a bull market will begin, but you can guarantee you're invested for it by staying fully invested through the dull stretches in between.
Frequently Asked Questions
Do active managers do better in bull markets?
Usually not. Broad rising markets reward staying fully invested, which favors index funds. Active funds carry cash drag, are often underweight the mega-cap leaders that drive modern bull markets, and still charge 0.5-1.0% a year. After those headwinds, the average active fund tends to lag the index in rallies.
Why does cash drag hurt so much in a bull market?
Active funds typically keep a few percent in cash for redemptions and flexibility. In a strong up year that uninvested cash earns far less than stocks, dragging on returns, while an index fund stays essentially fully invested and captures the full rally. The stronger the market climbs, the bigger that drag becomes.
Is there any bull market where active wins?
Occasionally in less efficient segments like small-caps or emerging markets, where the index isn't dominated by a handful of giants and mispricings are larger, skilled managers can add value during a rally. But even there a majority still lag over a full cycle, and picking the winners ahead of time remains difficult.
