While Turkey has shown the best performance of the tourism sector in the period 2000 years, the lowest performing period is the 1970s. WASPAS method was used in the study. The findings obtained provide the effectiveness of the WASPAS method. Under the ceteris paribus assumption that foreign exchange rates in Turkey are the key factors affecting the tourism sector. In a period when the exchange rates are rising, tourism revenues increase. This situation is also consistent with the findings obtained. In addition, possible effects of COVID 19 on the tourism sector were discussed. In total, the 52year performance of the tourism sector was examined. WASPAS is one of the multi-criteria decision making methods. It can be used in performance ranking. The decision matrix used in the application of the WASPAS method is a 52x6 type matrix consisting of 52 alternatives and 6 criteria. CRITIC and ENTROPY approaches were used as the weighting criteria (significance) of the criteria in the study. Both approaches give close results. The importance of the criteria was calculated as 16.67% for each criterion. Performance is the lowest in years when it is in the initial stage of Turkey's outreach efforts for many years. It is a natural result that tourism income and expenditure is low in these years. A result in line with our general expectation has been achieved. The explanation for the period of both crisis and high tourism performance is as follows. Tourism revenues are very sensitive to exchange rates. If there is an increase in exchange rates, there is an increase in tourism revenues due to the competitive prices of export products. In other words, tourism activities will be cheaper with the increase in exchange rates. Demand for goods and services will increase in a market where cheap prices prevail. Therefore, the positive effect of high exchange rate on tourism revenues under the assumption of ceteris paribus is the basis of the best performance years in the 2000s.. This result is also consistent with the result we got from the implementation phase.

The emerging markets contain the second group: Brazil, Russia, India, China, Turkey (BRIC –T). Finally countries suffering financial crisis take place: Spain, Portugal, and Greece. On the other hand, Gold, Brent Oil, LIBOR and Euro/Dollar parity are the macroeconomic variables that taken into account. The analysis contains daily data between 2005 and 2010. Having mentioned introduction and literature review, data and analysis takes place in the third part which is followed by analysis of countries according to groups.

This paper investigates the macroeconomic factors over stock markets. In order to get better solution, the stock markets divided into three categories: The first group is contained by developed financial markets: the USA, Japan, UK, Germany and France. The emerging markets contain the second group: Brazil, Russia, India, China, Turkey (BRIC -T). Finally countries suffering financial crisis take place: Spain, Portugal, and Greece. On the other hand, Gold, Brent Oil, LIBOR and Euro/Dollar parity are the macroeconomic variables that taken into account. The analysis contains daily data between 2005 and 2010. Having mentioned introduction and literature review, data and analysis takes place in the third part which is followed by analysis of countries according to groups. The results reflect a wide range of coefficients and signs of macroeconomic variables over stock exchanges. Therefore the coefficients and signs are depended on special cases for each country. Generalized Least Squares is the method that used for investigation.
