Galatasaray Sportif A.Ş.'s shares traded on the Borsa Istanbul stock exchange (BIST) brought a 56 percent profit to their investors at the beginning of the football season in September, marking the best performance on a monthly basis since January 2004.

Galatasaray's shares achieved the second highest monthly rise ever as a result of the football team's solid performance and expectations about its landed properties in Florya and Riva. The club's shares soared to TL 32.16 ($10) in September from TL 20.64 in August with a 55.8 percent rise, becoming the most profitable shares among others included in the BIST 100 index in September.

Galatasaray was followed by Beşiktaş Futbol Yatırımları A.Ş. in terms of profitability of shares at 7.6 percent in September. While Fenerbahçe Futbol A.Ş.'s shares increased by 3.4 percent, Trabzonspor Sportif A.Ş. was the only sports club bringing a loss to its investors at 3.6 percent down in the same month.

Galatasay's market capitalization surged to TL 696.1 million in September from TL 446.8 million in August. Analysts suggest that the successful performance of the football team supports its share prices, adding that expectations about revenue-generating projects on Galatasaray's landed properties in Florya and Riva had a part in the acceleration of the rise in shares.

As far as share revenues since the beginning of the year go, Trabzonspor comes to the fore as the fastest-rising football club. While the club's shares reached TL 2.93 with a 130.7 percent upsurge compared to the end of last year, though sales in September led to a 4 percent loss in shares for the month.
