Can we spot a Ponzi scheme earlier than it collapses? That query haunts regulators, buyers, and journalists alike. However what if some fashionable funding funds function on dynamics that, whereas not technically unlawful, intently resemble Ponzi-like habits? A brand new paper by Philippe van der Beck, Jean-Philippe Bouchaud, and Dario Villamaina examines whether or not sure actively managed funds inflate their very own efficiency — and in doing so, unwittingly mislead buyers chasing previous returns.
The examine reveals a hanging phenomenon: many funds generate a part of their returns by way of “value stress” — shopping for into the identical illiquid shares they already maintain, which drives up costs and boosts portfolio efficiency. Traders, unable to differentiate between real ability and self-inflated returns, pour more cash into these funds. That cash will get reinvested in the identical shares, pushing costs even larger. The authors name this suggestions loop “Ponzi-like” — not as a result of it’s fraudulent, however as a result of it mimics the wealth redistribution seen in precise Ponzi schemes: new buyers successfully reward early ones by way of rising costs that later collapse when flows dry up or markets right.
The implications are sobering. The paper finds that for essentially the most illiquid ETFs, as a lot as 10% of every day flows are pushed by these self-inflated returns — translating to an estimated $500 million in every day wealth reallocation throughout U.S. ETFs alone. Worse, funds with the very best ranges of this habits are sometimes those who undergo the steepest future drawdowns. To assist mitigate the danger, the authors suggest a easy metric — “fund illiquidity” — that captures a fund’s potential to generate self-inflated returns. In a time of booming thematic and area of interest ETFs, it’s a well timed warning: not all efficiency is created equal, and a few success tales could also be constructed on sand.

Title: Ponzi Funds
Hyperlink: https://arxiv.org/abs/2405.12768
Summary:
Many energetic funds maintain concentrated portfolios. Move-driven buying and selling in these securities causes value stress, which pushes up the funds’ present positions leading to realized returns. We decompose fund returns right into a value stress (self-inflated) and a elementary part and present that when allocating capital throughout funds, buyers are unable to determine whether or not realized returns are self-inflated or elementary. As a result of buyers chase self-inflated fund returns at a excessive frequency, even short-lived impression meaningfully impacts fund flows at longer time scales. The mixture of value impression and return chasing causes an endogenous suggestions loop and a reallocation of wealth to early fund buyers, which unravels as soon as the value stress reverts. We discover that flows chasing self-inflated returns predict bubbles in ETFs and their subsequent crashes, and result in a every day wealth reallocation of 500 Million from ETFs alone. We offer a easy regulatory reporting measure — fund illiquidity — which captures a fund’s potential for self-inflated returns.
As at all times, we current a number of attention-grabbing figures and tables:
Notable quotations from the educational analysis paper:
“[…] emphasize that the title of this paper doesn’t counsel that concentrated funding funds are literal Ponzi schemes as outlined by the SEC: “A Ponzi scheme is an funding fraud that includes the fee of purported returns to present buyers from funds contributed by new buyers.”4 As an alternative, the time period ‘Ponzi funds’ merely conveys the notion of self-inflated returns. The reallocation of capital occurs not directly through observable market costs as a substitute of direct capital transfers as in true Ponzi schemes. The SEC additionally states that “Ponzi schemes inevitably collapse, most frequently when it turns into troublesome to recruit new buyers or when numerous buyers ask for his or her funds to be returned.” That is nearer to our proposed mechanism, because the wealth reallocation from self-inflated returns unravels as soon as the value impression within the underlying securities reverts and buyers cease misinterpreting self-inflated returns as managerial ability.
Final, we mix the self-inflated returns with return chasing to quantify the financial significance endogenous value spirals brought on by impression chasing: Funds with concentrated portfolios in illiquid basket securities have a excessive potential impression on the underlying. Flows into these funds pushes up the value of the underlying, resulting in excessive realized fund returns. Following this value impression return, buyers allocate extra flows to those funds, which we label ‘Ponzi flows’. The financial magnitude of Ponzi flows and their value impression are significant. Round 2% of all every day flows and 8-12% of flows within the high decile of illiquid funds may be attributed to Ponzi flows. We estimate that daily round $500 Million of investor wealth is reallocated due to the value impression of Ponzi flows. We moreover discover that funds with excessive Ponzi flows expertise subsequent drawdowns of over 200%.
Determine 7 plots the relative Ponzi quantity over time.Among the many most illiquid funds (high decile ℐ), round 10% of the every day move quantity may be attributed to Ponzi flows, i.e. flows chasing previous value impression. Amongst all different funds, Ponzi flows are nonetheless sizeable and account for 2-3% of whole move quantity.
Determine 8(d) plots the cumulative returns over the occasion window for the run-up ETFs and the bubble ETFs.The black line studies the typical cumulative return over the occasion window throughout all run-up ETFs. As in Greenwood et al. (2019), extreme outperformance is on common not adopted by a subsequent crash. Cumulative returns moderately converge again to the market return. The crimson line splits the pattern of run-up ETFs into the funds that acquired the very best cumulative Ponzi flows fi,t𝒫 throughout the interval. On common, these bubble funds skilled steep crashes, with cumulative returns exceeding -200% within the two years following the runup. Nonetheless, as in Greenwood et al. (2019), timing the crash is troublesome. On common, bubble ETFs don’t crash throughout the first yr of the run-up.”
