The present study aims to develop the concept of predictive applicability of the Frequency Analysis of the Volatility and Trend (FAVT) as well as practical testing of the modified model for forecasting stock exchange indexes with different characteristics. For greater objectivity in estimating the forecast outcomes, FAVT is placed in parallel with traditional statistical models and the most popular method in stock exchange traders - technical analysis. In the first part of the study we develop the methodology of the concept of predictive applicability of FAVT in its modified version with movable calculation (FAVT-MC) of the frequency coefficients. The methodology of the study includes investment analysis measures, traditional statistical forecasting models, quantitative indicators of technical analysis and a modified version of the FAVT-MC. The conclusions of the statistical analysis show low applicability of linear forecasting in determining changes in the trend, while the alternative approach – non-linear forecasting yields significantly better results but under conditions of high investment activity and large variation. The choice of technical analysis tools is deliberately placed on quantitative measures known as technical indicators and does not include Eliot's Wave Theory. The results found are of varying reliability for the over ten technical indicators applied. Exploration of the forecasting significance of the FAVT with movable calculation for the main (long-term) trends on stock exchange indexes achieved results with a reliable signal value for the end of the large growth before the general stock market collapse at the end of 2007. Clearly unambiguous results for all the periods surveyed in the performance of the different stock indices regarding the change of their major trends after the 2008 crisis were not established. A more significant importance of the modified frequency analysis, allowing the reading of forecast signals, is established for the short-term trends of the stock exchange indices.

  Analysis and Assessment of the Policy Towards Foreign Direct Investment in Bulgaria in the Period 1990-2018

Foreign direct investment (FDI) has been regarded as an important driver of economic development in Bulgaria since the very start of market transition, which determined the establishment of a liberal foreign investment regime. However, the impressively large FDI stock, which was accumulated during the period of growth before the global crisis, has quite unfavorable sectoral and regional structure. In combination with the substantial drop of FDI after the crisis and its very low levels in the following years, this suggests that there are certain weaknesses of the policy towards FDI. Given the importance of the topic, the paper tries to analyze and assess FDI policy in Bulgaria. For this purpose, first we discuss some key features of inward FDI, then we outline the changes in the legislation in this field and in the end, some critical arguments and recommendations are given.
