We explore the effective gain or loss in alpha from the point of view of the investor due to the volatility of a fund and its correlations to other asset classes. Fund managers and investors can be guided by this to increase the utility that is ultimately delivered to the investor. In this analysis of investor utility the Sharpe ratio is shown to be misleading and the tracking error has no role...

Using a stochastic sequential game in ergodic equilibrium, this paper models limit order book trading dynamics. It deduces investor surplus and some agents’ strategies from depth’s stationarity, while bypassing altogether agents’ intricate forecasting problems. Market inefficiency adjusts to induce equal supply and demand for liquidity over time. Consequently, at a given bid-ask spread surplus ...

All HARA-utility investors with the same exponent invest in a single risky fund and the risk-free asset. In a continuous time-model stock proportions are proportional to the inverse local relative risk aversion of the investor (1/γ-rule). This paper analyses the conditions under which the optimal buy and hold-portfolio of a HARA-investor can be approximated by the optimal portfolio of an invest...

We present the optimal consumption and investment strategy for an investor, endowed with labor income, searching to maximize utility from consumption and terminal wealth when he is restricted to fulfill a binding capital constraint of a European (constraint on terminal wealth) or an American (constraint on the wealth process) type. In both cases the optimal strategy is proven to be of the optio...

In this paper, optimal consumption and investment decisions are studied for an investor who can invest in a fixed interest rate bank account and a stock whose price is a log normal diffusion. We present the method of the HJB equation in order to explicitly solve problems of this type with modifications such as a fixed percentage transaction cost and a mandatory bequest function. It is shown tha...

The crowdfunding industry is growing rapidly worldwide and poses new challenges on how to understand investment behavior. Indeed, a key challenge in this area is how to measure the similarity of an investor and a company, or the interest of an investor in a company. Tremendous effort has been made in previous research regarding the single effective factor or homogeneous network model based on l...

Prevailing models of capital markets capture a limited form of social influence and information transmission, in which the beliefs and behavior of an investor affect others only through market price, information transmission and processing is simple (without thoughts and feelings), and there is no localization in the influence of an investor on others. In reality, individuals often process verb...

We design an experiment to examine behavior and welfare in a multi-level trust game representing a pass through investment in an intermediated market. In a repeated game, an investor invests via an intermediary who lends to a borrower. A pre-experiment one-shot version of the game serves as a baseline and to type each subject. We alter the transparency of exchanges between non-adjacent parties....

Selections of stocks that are suitable for investment are always a complex task. The main aim of every investor is to identify a stock that has potential to go up so that the investor can maximize possible returns on investment. After identification of stock the second important point of decision making is the time to make entry in that particular stock so that investor can get returns on inves...
