Did Covid-19 Change how We Shop?

We study e-commerce across 47 economies and 26 industries during the COVID-19 pandemic using aggregated and anonymized transaction-level data from Mastercard, scaled to represent total consumer spending. The share of online transactions in total consumption increased more in economies with higher pre-pandemic e-commerce shares, exacerbating the digital divide across economies. Overall, the latest data suggest that these spikes in online spending shares are dissipating at the aggregate level, though there is variation across industries. In particular, the share of online spending in professional services and recreation has fallen below its pre-pandemic trend, but we observe a longer-lasting shift to digital in retail and restaurants.

The Implementation Costs of Indexed ETFs

A common mistake made by many passive investors is that they view all index funds in the same asset class as “commodities," often considering only the expense ratio when making their investment choices. However, not all index funds are alike, and not all passively managed funds (what I refer to as “systematically structured portfolios”) are index funds.

Can Market Maker Capital Constraints Result in Mispricing of ETFs?

Capital constraints of financial intermediaries can affect liquidity provision. We investigate whether these constraints spillover and consequently cause contagion in the degree of market efficiency across assets managed by a common intermediary. Specifically, we provide evidence of strong comovement in pricing gaps between ETFs and their constituents for ETFs served by the same lead market maker (LMM). The effects are stronger for ETFs that are more illiquid and volatile, when the underlying constituents of the ETFs are more costly to arbitrage, and for LMMs with more constrained capital. Using extreme disruptions in debt markets during COVID-19 as an experiment, we show that non-fixed income ETFs serviced by LMMs managing a larger fraction of fixed income ETFs experience greater pricing gaps. Overall, our results indicate that intermediaries’ constraints indeed influence comovements in pricing efficiencies.

Bond Investing in Inflationary Times

As the chief research officer of Buckingham Strategic Partners, the issue I am being asked to address most often is about fixed income strategies when yields are at historically low levels and inflation risk is heightened due to the unprecedented increase in money creation (through quantitative easing), the extraordinary expansionary fiscal spending around the globe, and the war in Ukraine driving prices higher (especially for food and energy). As always, to answer the question we turn first to the academic evidence on which investments in general provide the best hedges against inflation.

Shorting ETFs: A look into the ETF Loan Market

We find that exchange-traded fund (ETF) lending fees are significantly higher than stock lending fees. Two institutional features unique to ETFs play significant roles in explaining the high fees. First, regulations restrict investment companies, such as mutual funds and ETFs, from owning ETFs. As these institutions are key lenders, their absence reduces the lendable supply in the ETF loan market. Second, while the create-to-lend (CTL) mechanism alleviates supply constraints when borrowing demand increases, its efficacy is limited by the associated costs and frictions. Our results speak to the limits to arbitrage in the ETF markets.

Is Sector-neutrality in Factor Investing a Mistake?

Long-only factor performance is more likely to degrade from sector neutralizing—keeping the sector component produced better long-only factors in 78 percent of the trials. The largest negative from sector neutralizing occurred for the value-weighted long-only factors that trade large stocks, arguably the most investable portfolio.

Gaining an Edge via Textual Analysis of FOMC Meetings

How investors understand and use central bank communications, aka FEDSPEAK, is oftentimes cryptic and difficult to analyze. This study attempts to provide some clarity to this issue by applying textual analysis to both high-frequency price and communication data, to focus on episodes whereby stock price movements are identifiable and on investors’ reactions to specific sentences communicated by the Fed.

Are Stock Market Bubbles Identifiable?

Robin Greenwood, Andrei Shleifer, and Yang You authors of the study “Bubbles for Fama”, published in the January 2019 issue of the Journal of Financial Economics evaluated Fama's claim that stock prices do not exhibit price bubbles. Based on a fixed threshold for the industry price increases (e.g., a 100 percent price run-up during two consecutive years) to filter their events and to analyze what happens afterward, they examined U.S. industry returns over the period 1926‒2014 (covering 40 episodes) and international sector returns (1985‒2014).

The authors hypothesize that impression management consideration can also significantly determine investors’ conversations. This, in turn, can cause investors to inadvertently propagate noise with wide-ranging implications for the quality of investors’ investment decisions and asset prices.

2022 Democratize Quant Conference Recap and Materials

We recently hosted our Democratize Quant Conference (sign up here for updates).

This post is a recap of what we heard and some resources we can make available to the public.

Can Investment Flows Affect Prices? Yep.

Traditional finance theory suggests that stocks prices always reflect their fair market values based on publicly available information. Or in academic parlance, the "semi-strong" form efficient markets hypothesis serves as the null. What are the implications of this hypothesis? Well, the hypothesis suggests that the only reason a stock price will move is due to a shift in fundamentals (either through a change in expected cash flows or via the discount rate). But what about supply and demand shifts?

Employee Satisfaction and Stock Returns

“Employees are our greatest asset” is a phrase often heard from companies. However, due to accounting rules requiring that most expenditures related to employees be treated as costs and expensed as incurred, the value of employees is an intangible asset that does not appear on any balance sheet. That leaves the interesting question of whether employee satisfaction provides information on future returns.

What Percentage of Women Serve in Senior Investment Roles?

There is a “Pink” elephant in the room. The paucity of women in the key investment and decisión-making roles in finance is that “pink” elephant. While women are represented at 33%, 37%, and 63% in the law, medical, and accounting professions, respectively (Morningstar 2016), the percentage of female investment decision-makers in investment pales in comparison at less than 10%. And it gets worse if we look at sub-sectors. Take private equity, it’s 6% (Lietz, 2011), hedge funds at 3% (Soloway, 2011), or investment banking documented in this scorecard, at a global median of 0%.

Are Quant Approaches Best for Sustainable (ESG) Investing?

After 40 years or so, quantitative investing has evolved into a thriving practice. A major feature of the quantitative approach involves developing underlying numerical models and testing them on a historical (data) record and then forecasting where alpha may be embedded into the prices of a set of stocks. Whether you agree or disagree with this approach, it is difficult to deny that with the advanced state of data access and computational skill, “quants will win the day in ESG investing”. Such is the premise of this article and happily, it is accompanied by a compelling argument.

A Deep Dive into the Low Beta Premium

The superior performance of low-volatility stocks was first documented in the literature in the 1970s—by Fischer Black in 1972, among others —even before the size and value premiums were “discovered.” The low-volatility anomaly has been shown to exist in equity markets around the world. Interestingly, this finding is true not only for stocks but for bonds as well. In other words, it has been pervasive...but

Are Financial Crises Predictable?

Who among us wouldn't want to be the savior that predicts a market crisis and saves our clients from losses in capital -- or even better -- profits from them? A central topic of interest for academics is whether there are more precise tools to predict financial crises. Those who believe so dedicate their efforts to finding early warning indicators.

Factor Investing Premiums and the Economic Cycle

The main takeaway is that because factor timing is a strategy “fraught with opportunity,” investors should accept the fact that all risk strategies go through extended periods of poor (and unforecastable) periods of poor performance. As Blitz noted: “Even though investor sentiment may be more effective than the other metrics, its discriminatory power remains limited because expected factor premiums are still positive in all instances.” Thus, the prudent strategy is one of diversifying across many unique sources of risk so that not all of your risk eggs end up in the wrong basket at the wrong time.

An Introduction to Investing in Carbon Markets

Carbon markets are quickly making their way to the forefront of Environmental, Social, and Governance (ESG) investing, as well as the finance community as a whole. The Kraneshares Global Carbon ETF, (Ticker: KRBN) (whose holdings I’ll dive into shortly) was one of the top 5 performing ETFs in 2021 on a % return basis (Ferringer, Best performing ETFs of the Year - etf.com). However, it doesn’t appear that 2021 was a one-hit-wonder for Carbon Markets, but instead, the beginning of a new and very real trend.
