TEDPIX, TSE's Price and Dividend Index, became the world’s second-best performing equity index in 2010.

2007: The market bottomed in June 2007 mainly because of the renewed privatization drive in the Iranian economy.

2008: The TSE was not directly affected by the international financial turmoil in 2008, but following the global reduction in prices of copper and steel, the bourse index dropped by 12.5 percent, as most of the companies listed on the exchange are producers of such commodities. TSE experienced an 11% growth at the end of 2008 and ranked second in the world in terms of increase in the volume of trade after Luxembourg’s Bourse.

2009: The TSE sank about 40% in value between August 2008 and March 2009, influenced by falling oil prices and declining markets in other parts of the world. As of August 1, 2009 it has recovered by more than 10%. During Iranian year 2009/10, the value of capital market was around $20 billion. Some 3 million trade exchanges were made, pushing up the index to 12,500 units from the previous 8,000 units.

2005-2006: In December, 2005, 419 companies with a market capitalization of IRR 32,741.7 million were listed in TSE. The TSE has had an exceptional performance over the past 5 years. In general, the stock market in 2005/06 shed value as it is manifested by the decline of its major stock price indices. The TSE price index (TSPIX) at the end of 2005/06, declined by 21.9%, while the Financial Sector Index, and the Industrial Index, declined by, 38.8%, 19.4% respectively, and the Dividend Index gained 11.8%, mostly due to a reported 100 billion USD capital flight from the country because of the international dispute surrounding the Iranian nuclear programme.

2000-2004: The performance of the TSE has had no correlation with major exchanges or emerging stock markets over the past few years and not even with the oil price. While the overall indices of the world’s five major exchanges – New York, London, Paris, Frankfurt and Tokyo plunged by 40 to 70% between March 2001 and April 2003, the TSE index (Tepix) bucked the trend by going up nearly 80%.

2010: In the first month of this Iranian year (March 20-April 21, 2010), the index hit the 14,000 unit mark from the previous 12,500 units, showing a 12-percent growth. The value of last month trading transactions exceeded $1 billion against last year's corresponding period of $95 million. Tehran Stock Exchange bourse index from June 2009 to 2010 grew 55 percent and the current value of TSE's total market capitalization went up to about 33 percent and hit over $71 billion.

On August 2, 2010, TSE main index (TEPIX) hit the highest-ever historical record of 16,056 points, despite US-sponsored sanctions against Iran. Thus, TEDPIX became the world’s second-best performing equity index. Factors such as the global spike in oil and metal prices, government support for industries and oil sectors as well as the growth of stock market liquidity flow have contributed to the recent boom. Experts say the growth is also partly due to a government decision to sell off 20 percent of its equity in two major automakers. Given the relative low market valuation of TSE stocks at present, the upward trend is expected to continue over the long run and it is not a bubble.

TEPIX reached a new record on September 18, 2010, when it hit 18,658, up from 11,295 at the start of the year.
