Borsa Istanbul is in a cheaper position compared to other stock markets and its own averages in terms of technical and basic indicators while it has occupied the headlines with its recent records.In terms of price-earnings (P/E) ratio and market value comparison, which leads the way among the criteria used by analysts to decide on stock investments, Borsa Istanbul share markets display an image that can be considered as "cheap," while it is noteworthy that it points to a 95 percent yield potential in technical terms, according to the historical peak of the dollar-based BIST 100 index.The average P/E ratios of the stocks traded on Borsa Istanbul indicate a significant yield potential compared to the leading stock exchanges. Considering the stock markets that have a place in the world markets in terms of depth and liquidity, the only country with a /E ratio below the five-year average is Turkey, while Russia leads the way with the lowest P/E ratio.P/E, the ratio of a company's current share price relative to its per-share earnings, comes to the fore as one of the most influential indicators on investor decisions all over the world. The P/E ratio, which is one of the indicators used to compare companies and stocks with their counterparts and regard them as cheap or expensive, is being used by analysts as a guideline in terms of predicting the future price movements when calculating the expected per-share profit rather than the realized.According to analysis by data terminals and investment companies, Indian and U.S. stock markets with P/E ratios approaching 18 percent became the two "most expensive" stock exchanges.

On the basis of valuation, Turkey's share markets are trading at about 32 percent discount as P/E multiplier compared to the developing markets.It is noteworthy that in Russia, which has a cheaper stock market image than Turkey with 5.5 percent, this ratio is above the five-year average in-house unlike in Turkey.On the other hand, although the BIST 100 index reaches a record level with 94,880.68 points today in TL terms, the dollar-based course of the index needs to be followed to make accurate long-term assessments.Accordingly, the BIST 100 index, which was in peak form with 48,000 points in 2007, 51,000 in 2010 and 50,000 in 2013, in dollar terms, could only reach 26,400 points this year with the rally, staying far from its highest point.BIST 100 index reverses 4-year decline trend
