It was reported that the investigation was initiated following evaluations Turhan made on his social media account. In his post regarding the decline in Borsa İstanbul exceeding 6 percent, Turhan had stated that he did not see a "fundamental and structural risk" in the capital market.

In his post, Turhan argued that the Turkish economy is strong, that there is no risk affecting all publicly traded companies, and that companies without profitability and free cash flow problems are in good condition.

Using the phrase "One must remain calm" in his post, Turhan stated that investors acting in panic could cause the greatest harm to themselves, and that this could also lead to market deterioration and make the problem appear larger than it is.

Turhan also wrote that current stock market developments could be evaluated within the framework of capital movements experienced in emerging markets following the 1997 Asian crisis and the 1998 Russian crisis.
