Liquidity Risk Measurement for Mutual Funds Investing in Less-Liquid Assets

Opis:
I apply two models from the existing academic literature to assess liquidity risk in groups of mutual funds as well as in individual high yield mutual funds. These models are a serial correlation model with an AR(1) process and a lagged effects model. These models were most recently applied in the field of hedge fund research to measure liquidity risk and to evaluate the performance of aggregated groups of hedge funds, organized by investment strategy. I apply these models in the recently developing area of liquid alternative mutual funds and at the level of the individual mutual fund. A perceived benefit to investors in the liquid alternative funds is the structural, daily-redemption liquidity of the fund shares. Yet, the liquidity of the underlying securities portfolios held by these funds is not apparent to the investors and may expose the investor to heightened liquidity risk. The models perform well and will be applied to identify liquidity risk in a further ongoing study of the performance and liquidity of individual mutual funds. Liquidity risk assessment should play a vital role in performance evaluation and fund selection

Advances in antithetic time series analysis: separating fact from artifact

Opis:
The problem of biased time series mathematical model parameter estimates is well known to be insurmountable. When used to predict future values by extrapolation, even a de minimis bias will eventually grow into a large bias, with misleading results. This paper elucidates how combining antithetic time series solves this baffling problem of bias in the fitted and forecast values by dynamic bias cancellation. Instead of growing to infinity, the average error can converge to a constant.

Implications of market frictions: serial correlations in indexes on the emerging stock markets in Central and Eastern Europe

Opis:
Implications of market frictions in the context of serial correlations in indexes on the Central and Eastern European (CEE) stock markets have been analysed. Market frictions, such as non-trading effects, bid/ask spreads, other transaction costs, etc., may be detected by direct measurement, or by indirect identification. Direct measurement of frictions is difficult as intraday trading data are unavailable in the case of most of the emerging CEE stock markets. Indirect identification may be conducted by detecting some empirical phenomena. One of them is evidence of serial correlations in indexes, the so-called the Fisher effect. We explore the problem of serial correlations in indexes on the eight CEE stock markets using data samples from each CEE market separately, as well as a “common trading window” approach, which is widely applied in the case of databases with multivariate time series. The evidence is that nonsynchronous trading effect II between markets may substantially disrupt the analysis of index returns on a domestic market. Using a synchronized database, one may erroneously conclude that the Fisher effect does not exist, although it is present.

Re-Evaluating Sharpe Ratio in Hedge Fund Performance in Light of Liquidity Risk

Tematy:
liquidity risk

Sharpe ratio

Opis:
This paper demonstrates how the Sharpe Ratio can be modified by altering the measure of “total risk” in the denominator of the Sharpe Ratio (i.e., the standard deviation) to include liquidity risk, a major risk for investors in hedge funds that is missing from the standard Sharpe Ratio formulation. We refer to our liquidity-risk-adjusted performance ratio as the LRAPR. The results of our analysis of 1186 hedge funds alive in 2012–2020 show that funds with higher liquidity risk exhibit higher Sharpe Ratios and higher Alphas (as estimated in a 7-factor model that does not incorporate liquidity risk). We posit that analysts and investors should not necessarily take these higher Sharpe Ratios and higher Alphas as indications of fund superiority; what appears to be superior manager skill may rather be a compensation for bearing liquidity risk. Our LRAPR is a tool that analysts or investors could use to compare funds on a more equal footing, adjusting for differential liquidity risk across funds.

Opis:
The article presents the characteristics of temperature changes of selected components of the machine tool and the temperature of the machining coolant in relation to the selected dimensions of finished parts, such as the AGB gear cover. The tests were carried out on the basis of serial production on the FMS line in a plant producing components for the aviation industry. As part of the research, the machine tool was modernized to the extent that it was possible to register temperatures in real-time. Temperature changes were compared with the dimensions of the machined part in search of dependencies. Correlation calculations between temperature and dimensional data were made with the use of a statistical process control program. Dimensional data were obtained from CMM machines used daily to measure parts from series production.
