Desirable attributes for financial portfolios include persistence, smoothness, long memory, and higher auto-correlation. We argue that these properties can be achieved by adjusting the composition weights of the portfolio. Considering the fractal nature of typical financial time series, the fractal dimension emerges as a natural metric to gauge the smoothness of the portfolio trajectory. Specifically, the Hurst exponent is designed for measuring the persistence of time series. In this paper, we introduce an optimization method inspired by the Hurst exponent and signal processing to mitigate the irregularities in the portfolio trajectory. We illustrate the effectiveness of this approach using real data from an S &P100 dataset.}, year = {2024}, eissn = {1573-2878}, orcid-numbers = {Zlatniczki, Ádám/0000-0003-3088-441X; Telcs, András/0000-0002-3205-3081} } @article{MTMT:34765018, title = {Analogies and Relations between Non-Additive Entropy Formulas and Gintropy}, url = {https://m2.mtmt.hu/api/publication/34765018}, author = {Biró, Tamás Sándor and Telcs, András and Jakovác, Antal}, doi = {10.3390/e26030185}, journal-iso = {ENTROPY-SWITZ}, journal = {ENTROPY}, volume = {26}, unique-id = {34765018}, year = {2024}, eissn = {1099-4300}, orcid-numbers = {Biró, Tamás Sándor/0000-0001-6188-8478;
