Further reading: Robinhood’s effect on stock market quality
The Investors Chronicle
Stock trading commissions have been in steady decline for many years, making investment more accessible and helping to lift the proportion of retail investors in the US stock market from 10 per cent in 2010 to 20 per cent last year. But it is the arrival of zero trading commission platforms with no account minimums which has ushered in a new era of stock market participation, particularly in the US. Robinhood, the pioneer of commission-free trading, reported 3 million new accounts in the first quarter of 2020 alone, as lockdowns put many other activities on hold.
Robinhood Traders Have a Troubled Track Record of Stock Picking
“Robinhood investors’ evident lack of skill in aggregate is consistent with commission-free investors behaving as uninformed noise traders,” wrote Gregory W. Eaton and Brian S. Roseman from Oklahoma State University and T. Clifton Green and Yanbin Wu from Emory University. The authors also found that stocks with buzz on WallStreetBets see a spike in activity on Robinhood a few days later, a sign there’s likely much overlap between the two communities.
The most frequently asked questions by Robinhood traders reveal ‘new type of uninformed equity-market participant’
When at least some of the Robinhood users could not trade because of platform problems, the stocks those Robinhood users commonly owned “all become more liquid, easier to trade and less costly to trade and less volatile,” said paper co-author Clifton Green of Emory University. The research comes on the heels of a warning from Owen Lamont, associate director of multiasset research for Wellington Management’s Quantitative Investment Group, that the GameStop saga illustrates rising “noise-trader risk” that could feed market volatility.

The “likability” and even the pronounceability of a ticker symbol (think: BRO, ACE, LOL) are positively related to a stock’s value.

Separating Alpha From Beta Is Best Done With CAPM
“Exotic beta is alpha,” the trio of researchers said when hedge fund allocators view capital deployment. Confusing the two, particularly in investments where measures of beta are hard to come by or often privately deployed, can be particularly challenging. “Although we find strong evidence of persistence for alpha, persistence in hedge fund returns attributable to traditional and exotic risk exposures is modest, which suggests investors would benefit from employing more sophisticated risk models when evaluating fund performance,” Vikas Agarwal and T. Clifton Green from Georgia State University and Honglin Ren from Emory University conclude...

Economic news and the impact of trading on bond pricesThe Journal of Finance
2004 This paper studies the impact of trading on government bond prices surrounding the release of macroeconomic news. The results show a significant increase in the informational role of trading following economic announcements, which suggests the release of public information increases the level of information asymmetry in the government bond market. The informational role of trading is greater after announcements with a larger initial price impact, and the relation is associated with the surprise component of the ...
Market efficiency in real timeJournal of Financial Economics
2002 The Morning Call and Midday Call segments on CNBC TV provide a unique opportunity to study the efficient market hypothesis. The segments report analysts' views about individual stocks and are broadcast when the market is open. We find that prices respond to reports within seconds of initial mention, with positive reports fully incorporated within one minute. Trading intensity doubles in the first minute, with a significant increase in buyer-(seller-) initiated trades after positive (negative) reports. Traders who execute within 15 seconds of ...
Economic news and bond prices: Evidence from the US Treasury marketJournal of Financial and Qualitative Analysis
2001 This Paper uses intraday data from the inter dealer government bond market to investigate the effects of scheduled macroeconomic announcements on prices, trading volume, and bid-ask spreads. We find that 17 public news releases, as measured by the surprise in the announced quantity, have a significant impact on the price of the following instruments: a three-month bill, a two-year note, a 10-year, and a 30-year bond. These effects vary significantly according to maturity. Public news can explain a substantial fraction of ...
Market risk and model risk for a financial institution writing optionsThe Journal of Finance
1999 Derivatives valuation and risk management involve heavy use of quantitative models. To develop a quantitative assessment of model risk as it affects the basic option writing strategy that might be followed by a financial institution, we conduct an empirical simulation, with and without hedging, using data from 1976 to 1996. Results indicate that imperfect models and inaccurate volatility forecasts create sizable risk exposure for option writers. We consider to what extent the damage due to model risk can be limited by pricing ...
Tax and liquidity effects in pricing government bondsThe Journal of Finance
1998 Daily data from interdealer government bond brokers are examined for tax and liquidity effects. We use two approaches to create cash flow matching portfolios of similar securities and look for pricing discrepancies associated with liquidity or tax effects. We also look for the presence of tax and liquidity effects by including a liquidity term when fitting a cubic spline to the after-tax yield curve. We find evidence of tax timing options and liquidity effects. However, the effects are much smaller than previously reported and the effects of ...
