The Market's Biggest Investors Are Trading, Not Investing

02Round-tripping reveals a lack of understanding

Changing an investment thesis when the facts change is rational.

But businesses do not transform at the frequency required to explain this degree of reversal.

A scaled public company has customers, products, employees, competitors, distribution systems and demand patterns that develop over years. Breaks from trend occur, but nowhere near often enough to explain industry-wide round-tripping.

A portfolio manager bought the business, sold it and bought it again. Businesses did not break and heal at this frequency. The portfolio managers' interpretations moved.

Round-tripping is the manifestation of an underdeveloped point of view. It reveals that the original position was not supported by enough research or enough understanding to produce real conviction.

Deep research takes time. It requires understanding products, customers, competition, demand, unit economics and the forces shaping the business's trajectory. A portfolio manager who has done that work anchors decisions to business evidence.

Round-tripping shows that many of the market's largest participants are anchored to something else: the stock price and the prevailing narrative.

That is trading, not investing.

03Trading behavior drives market volatility

Mutual funds represent the dominant pool of capital operating in public markets. When many of them sell at the same time, their transactions drive the stock sharply lower.

The falling price does not merely reflect investor behavior. It changes investor behavior.

A sharp decline is treated as new information. It validates negative narratives, triggers momentum selling, causes risk models to cut exposure, prompts analysts to lower expectations and pressures other portfolio managers to sell.

In fact, our holdings analysis found that when a mutual fund exited or materially reduced a position, 42% of the other mutual funds holding that stock were also materially selling it within a two-quarter window. Among hedge funds, the figure was 64%.

The price decline creates more selling, and the additional selling drives the price lower still. This is a massive domino effect triggered by a capital bloc with shallow business views and little conviction. The feedback loop works in reverse when a rising price draws buyers back in.

This is a defining difference between public and private markets. Private companies are not assigned a new auction price every second, so their investors are not repeatedly confronted with a falling price that pressures them to act. Public-market investors are.

The business can remain on the same underlying trajectory while the stock price drives wave after wave of portfolio decisions. The volatility belongs to the trading system, not to the rate of change in the business.

Volatility and deterioration are not the same thing. The market routinely confuses them because its largest participants are reacting to price.

04Deep research creates conviction

Round-tripping amplifies the value of deep research.

Research builds an understanding of product adoption, customer reception, competition, structural demand, operating leverage and the power of the business model. That understanding creates a durable view of the business's trajectory.

Selloffs often begin with doubt, not concrete evidence that the trajectory has broken. A falling price gives that doubt force and turns it into the prevailing narrative.

The market movers do not have the same visibility. They do not know that a new product is setting up accelerating revenue growth. They do not see operating leverage poised to multiply earnings. They do not understand why a marketplace is benefiting from a structural trend with immense durability.

They react to the stock because they do not understand the business well enough to distinguish a falling quote from a broken trajectory.

As time passes, durability becomes undeniable. Customer behavior repeats, structural demand compounds and the power of the business model appears in revenue, margins and earnings. The evidence was present before; reported results make it obvious.

Many of the investors who sold in response to doubt will return. The round-trip begins again.

05Their trading creates the investor's opportunity

For institutions that own individual stocks, or may consider doing so over time, this is not an abstract critique of Wall Street. It changes how a selloff should be read.

A major selloff is not a reliable judgment on a business. It is the output of investors rushing out of a stock without a deeply researched view of what they own.

Discount the narrative surrounding the selloff. Use the price decline as an initial screen, then do the research required to separate the gems from the coal. Sometimes the market movers are selling businesses they should never have owned.

Other times they are abandoning powerful businesses with structural demand, strong business models and durable trajectories. Those are the opportunities.

Round-tripping gives an informed investor confidence that sentiment will reverse. When the strength of the business becomes visible in reported results, many of the same investors will return.

The market's largest investors have trillions of dollars to deploy and redeploy. Their scale drives the auction. It also creates a durable opportunity for investors willing to approach the market one business at a time.

A smaller institution does not have to match their speed or scale. It can wait, study one business deeply and act when the behemoths create an unusually attractive price in an unusually durable business.

The behavior also cuts both ways. Our analysis found that 96% of mutual fund portfolio managers bought up a stock and later reversed that decision 62% of the time. Among hedge funds, 94% did so and reversed 60% of the time. The same mechanical buyers who drive a stock higher can become sellers again.

We use a dynamic hedging strategy to manage these reverse round-trips. We will share that approach in a future note.
