Invesco Dorsey Wright Momentum ETF (PDP)

PDP is an exchange-traded fund that invests in large-cap US stocks showing strong upward price momentum and improving earnings. It is managed by Invesco and uses a system designed by Dorsey Wright Money Management to identify and weight the stocks most likely to sustain that momentum through the next quarter.

The momentum selection process

The fund’s strategy rests on a specific observation: stocks that have been rising tend to keep rising for a time, especially when their earnings are also improving. This is not magic or market arbitrage; it is a documented pattern that professional traders and systematic investors have exploited for decades. PDP captures this pattern by holding roughly 50 to 100 large-cap US stocks selected and weighted according to Dorsey Wright’s momentum framework.

Dorsey Wright applies a technical-analysis lens to the selection process. The system scores stocks on measures including price strength, relative strength versus the broader market, and earnings revision trends. Stocks with the highest combined scores become the fund’s core holdings. The selections are refreshed quarterly, usually on Fridays that open a new quarter, so the fund transitions in and out of positions on a regular schedule.

What makes momentum investing distinct

Momentum is one of several documented stock-market patterns, alongside value (buying cheap stocks), quality (buying profitable, stable businesses), and size (the behaviour of large versus small companies). It is also one of the most emotionally counterintuitive: while many investors are trained to “buy low and sell high,” momentum investing explicitly buys stocks already up and sells those already down, making it feel like chasing performance. Yet the academic evidence and the long track record of momentum strategies suggest that this pattern persists. Invesco and Dorsey Wright are betting that it continues to do so.

That said, momentum is also cyclical. Momentum strategies tend to outperform during risk-on periods when investors are willing to reach for growth and push up the stocks that are already winning. In downturns and defensive markets, momentum often lags, because the stocks that have risen the most tend to fall the hardest when sentiment turns. Periods of rotation out of growth stocks into value stocks can be painful for momentum funds.

Holdings and sector composition

Because PDP selects from the largest US companies and uses a momentum lens, it typically tilts toward large-cap growth sectors like information technology and consumer discretionary. During periods when growth stocks are in favour, this overlap can amplify the fund’s returns. During periods when the market favours dividend-paying value stocks or more defensive sectors, PDP may lag. The fund’s sector weightings shift naturally as momentum carries different sectors in and out of favour over time.

The holdings are transparent. Invesco publishes the current list regularly, and investors can always see what they own. There is no hidden process; the system is systematic and repeatable. This transparency also means the fund’s quarterly rebalancing dates are known in advance, which has led to predictable flows in and out of the stocks being added and dropped.

Costs and liquidity

PDP charges an expense ratio that covers Invesco’s management, the Dorsey Wright licensing fee, and the costs of quarterly rebalancing. The ratio is reasonable but not the lowest among US large-cap equity ETFs, reflecting the active stock-picking embedded in the strategy. The fund trades on an exchange with solid liquidity, so buying and selling is usually straightforward.

Tracking and volatility

PDP does not track a published index in the way, say, a Standard & Poor’s 500 fund tracks the S&P 500. Instead, it follows the Dorsey Wright Large-Cap Relative Strength Index, which is proprietary to Dorsey Wright Money Management. That means the fund’s performance is tied to how well Dorsey Wright’s system works, not to a passive benchmark. Investors are betting on skill, not just passive exposure.

Like all momentum strategies, PDP will exhibit greater volatility than the broad market during risk-off periods, when momentum often breaks down most sharply. The fund rises faster on up days in growth-favoured environments and falls faster on down days when sentiment shifts. That higher volatility is the trade-off for the potential alpha that momentum offers.

Who should consider PDP

PDP suits investors who believe momentum is a real, persistent pattern in stock markets, who can tolerate the periods when momentum underperforms, and who want systematic exposure to that factor without picking individual stocks. It is useful as a satellite holding around a core US stock position, especially for investors who can psychologically handle owning the stocks that have already risen sharply, rather than the cheap ones that feel safer.

It is not suitable for passive, buy-and-hold investors who want stable, low-volatility exposure to large-cap US equities. Those investors would be better served by a broad market index fund. PDP is an active bet on a specific market factor, and it requires the belief that the factor will deliver over the holding period.

How to research PDP

Start with Invesco’s fund fact sheet and prospectus, which detail the selection criteria and rebalancing methodology. Look at PDP’s historical performance relative to broad market indices in different market environments: rising markets, falling markets, periods when growth is in favour, and periods when value outperforms. Understand that past performance in any market environment does not guarantee future results. Watch the fund’s turnover and tax efficiency in taxable accounts; quarterly rebalancing implies meaningful trading, which can trigger capital-gains distributions.

Finally, consider the broader momentum literature. Academic research on momentum is extensive, and reading summaries of that work will deepen your understanding of whether this is a factor you want to own, and when it is likely to help or hurt your returns.
