A deep-ingrained doctrine in asset pricing says that if an empirical characteristic-return relation is consistent with investor “rationality,” the relation must be “explained” by a risk (factor) model. The investment approach questions the doctrine. Factors formed on characteristics are...

Financial basics and intuition stresses the importance of investment horizon for risk management and asset allocation. However, the beta parameter of the Capital Asset Pricing Model (CAPM) is invariant to the holding period. Such contradiction is due to the assumption of long-term independence...

The purpose of this research is revelation of mechanisms of emerging crisis, turbulent events in markets, with singling out the advantageous stable phase, turbulent phase and non-advantageous stable phase.The idea of this work was to research impact of change of assets market parameters in the...

This paper examines the determinants of cross-sectional variation in post-merger mutual fund performance. Mergers between funds with similar management objectives, as reflected by average portfolio book-to-market ratio, price-earnings ratio, beta and market capitalization values, outperform...

Using an hourly dataset on retail investor security positions from Robinhood Markets, we find that ESG disclosures are irrelevant to retail investors' portfolio allocation decisions. The response to ESG press releases by retail investors is no different than the routine portfolio adjustments...

Disagreement about stock valuation, combined with short-sales constraints, can increase asset prices. We build a model showing that, so long as investor beliefs are not perfectly correlated, investors will disagree less about the value of a conglomerate than about each of its individual...

We find that leverage-initiating stocks experience an increase in return comovement with existing leveraged stocks and a decrease in return comovement with existing zero-leverage stocks in the year after the leverage initiation event. In contrast, stocks that fully deleverage comove more with...

We study firm-level characteristics that a manager would employ as signalling tools in order to time the market (i.e. repurchases and issues). Following the market timing framework, we develop a two-factor asset pricing model comprising a “market” and a “mispricing” factor, which is able...

Several prominent studies use mutual fund fire sales as exogenous price shocks. They find clear feedback effects, wherein stock prices affect firm policies. I show that selection bias invalidates fire sales. Large mutual fund outflows affect small and micro-cap mutual funds disproportionately,...

This study uses stock lending data from Data Explorers to assess the impact of short-selling constraints on the profitability of eight investment strategies. Returns from unconstrained long-short portfolios are compared with those from ‘feasible' portfolios, constrained to short-selling only...
