Evidence suggests that arbitragers exchange investment ideas. We analyze why and under what circumstances sharing occurs. Our model suggests that sharing ideas will lead to the following: more efficient asset prices, larger arbitrager profits, and correlated arbitrager returns. We predict that...

The following article considers the practical use of temporary connections that arise between different exchange assets. The concrete recommendations to build a trading strategy based on the theory of market focuses are proposed. The main idea in this case is that strong positive correlation...

Maximization of result from operations with securities is not always ultimate goal of participants. For example, result can be exchanged into different currencies. There can be different utility functions that transform result into some asset. Different risk-neutral probability densities could...

The notion of Net Present Value (NPV) is thought to formally translate the notion of economic profit, where the discount rate is the cost of capital. The latter is the expected rate of return of an equivalent-risk alternative that the investor might undertake and is often found by making...

This article is a supplement to previously published paper [1]. It represents a theoretical example that demonstrates a strategy based on exploiting of found market inefficiency. It is fundamental. Thus, what markets without this inefficiency should be is an open question. It is connected to...

This paper focuses on inconsistencies arising from the use of NPV and CAPM for capital budgeting. It shows that (i) CAPM capital budgeting decision-making based on disequilibrium NPV is deductively inferred by the Capital Asset Pricing Model, (ii) the use of the disequilibrium NPV is widespread...

New approach to determining no arbitrage conditions is presented in this paper. Determined by supply and demand prices are used instead of assumptions about price processes. Special attention was made to alternative numeraire change technique that was obtained using presented approach. Results...

This paper shows that (i) project valuation via disequilibrium NPV+CAPM contradicts valuation via arbitrage pricing, (ii) standard CAPM-minded decision makers may fail to profit from arbitrage opportunities, (iii) standard CAPM-based valuation violates value additivity. As a consequence, the...

This paper shows that a decision maker using the CAPM for valuing firms and making decisions may contradict Modigliani and Miller’s Proposition I, if he adopts the widely-accepted disequilibrium NPV. As a consequence, CAPM-minded agents employing this NPV are open to arbitrage losses and miss...

This paper deals with the CAPM-derived capital budgeting criterion, and in particular with Rubinstein’s (1973) criterion, according to which a project is profitable if the project rate of return is greater than the risk-adjusted cost of capital, where the latter depends on the project’s...
