ProShares Launches First ETF Targeting Buyback Aristocrats

ProShares launched the ProShares S&P 500 Buyback Aristocrats ETF (BUYB) today, the first ETF focused exclusively on companies with a long track record of buying back their stock.

The fund charges 0.39% and steps into the ring with the $1.7 billion Invesco BuyBack Achievers ETF (PKW). 

The two funds take very different approaches to the same theme. BUYB holds companies that have reduced shares outstanding for at least 10 consecutive years and equal weights them, which produces a concentrated portfolio of just 64 names, or about 13% of the S&P 500. 

PKW, by contrast, holds stocks that have cut shares outstanding by 5% or more in the trailing 12 months and uses float-adjusted modified market cap weighting, which yields a much broader 227-stock portfolio. PKW charges 0.62%, considerably more than BUYB.

The Case For BUYB

The case for BUYB over PKW is that consistency matters more than the size of any single year's buyback. The S&P 500 Buyback Aristocrats Index it tracks only launched in December 2025, but back-tested data shows the index returning 1,023% since PKW's December 2006 inception, versus 583% for PKW and 633% for the S&P 500. 

Of course, back-tested performance is no guarantee of what comes next, but one can certainly make a case for why such a strategy might continue to outperform over the long term.

Companies that can sustain buybacks for a decade or longer may be the kind of high-quality, cash-generative businesses that generate strong returns for investors. BUYB's current holdings include Qualcomm, Apple, eBay, Applied Materials, and DaVita.

The Dividend Aristocrats Parallel

While the buyback version is new, the broader idea of investing in companies that have stuck with a shareholder-friendly policy year after year already has a long, well-established analog on the dividend side.

The Vanguard Dividend Appreciation ETF (VIG), which requires 10 years of dividend growth, has $106 billion in assets. The ProShares S&P 500 Dividend Aristocrats ETF (NOBL), which holds the bar at 25 years, has $11 billion. 

ProShares is clearly hoping for similar success with BUYB. But dividend funds have one advantage buyback funds don't, which is the automatic cash payment investors see in their accounts. 

Total returns are what ultimately matter—and buybacks are often more tax-efficient than dividends since the gains are deferred until investors sell—but plenty of investors don't think that way.

Another thing to keep in mind is that any 64-stock equal-weighted portfolio is going to look very different from the broader market. 
The sector tilts for BUYB are significant. The ETF is overweight industrials at 28% (vs. 9% for the S&P 500), consumer discretionary at 20% (vs. 10%), and financials at 19% (vs. 12%). 

On the other hand, it's underweight tech at 11% (vs. 36%) and communication services at 2% (vs. 11%). 

To the extent tech and communications keep leading the market, BUYB will lag.
