Informed Trading, Order Flow Shocks and the Cross Section of Expected Returns in Borsa Istanbul
(Routledge Journals, 2020) Tiniç, Murat; Salih, Aslihan
This paper examines the relationship between information asymmetry and stock returns in Borsa Istanbul. For all stocks that are traded in Borsa Istanbul between March 2005 and April 2017, we estimate the probability of informed trading (PIN) to proxy for information asymmetry.? Firm-level cross-sectional regressions indicate a statistically insignificant relationship between PIN estimates and future returns. Moreover, univariate and multivariate portfolio analyses assert that investors that hold stocks that have high information asymmetry do not obtain significant future returns. Consequently, our results suggest that information asymmetry proxied by PIN is a firm-specific risk and can be eliminated with portfolio diversification. Findings are robust to different factorizations in estimating PIN and free of any bias due to trade classification algorithms, boundary solutions, floating-point exceptions and symmetric?order flow shocks.

Who To Trust? Reactions To Analyst Recommendations of Domestic Versus Foreign Brokerage Houses in a Developing Stock Market
(Elsevier Ltd, 2021) Tanyeri, Başak; Bodur, Mehmet; Tiniç, Murat
Announcement day abnormal returns around analyst recommendations of upgrades average 35 and downgrades average -45 basis points in Borsa Istanbul. The nationality of the investment bank issuing the recommendation affects the magnitude of the stock market reaction. The absolute magnitude of abnormal returns upon upgrade and downgrade recommendations of foreign investment banks is larger than that of local investment banks. The differential reaction indicates that in a developing market country, Turkey, investors pay closer attention when the source of information is foreign rather than local.

Political Turmoil and the Impact of Foreign Orders on Equity Prices
(Elsevier, 2020) Tiniç, Murat; Savaşer, Tanseli
This paper examines whether foreign investors possess an information advantage over local investors in the Turkish stock market between 2007 and 2015. We find that foreign investors have an information advantage in 24 stocks, corresponding to seven percent of the sample firms. Foreign investors' information advantage tends to prevail primarily during a period of political instability, which started with the Gezi Park protests in June 2013. The adverse selection component of the foreign trade spreads, which reflects a permanent change in stock prices, rises significantly after June 2013, by 66 bps. Our results suggest that domestic investors' funding constraints, which limit their ability to impart their information on stock prices, may give foreign investors a relative information advantage during periods of political turmoil.

Information Cascades, Short-Selling Constraints, and Herding in Equity Markets
(Borsa İstanbul Anonim Şirketi, 2020) Tiniç, Murat; Iqbal, Muhammad Sabeeh; Mahmud, Syed F.
This paper examines the relationship between informed trading and herding in Borsa İstanbul. Our firm-level cross-sectional analysis asserts that informed trading can significantly increase future herding levels. Furthermore, we show that the relationship between informed trading and herding intensifies under short-selling restrictions. Our results confirm the predictions of the informational cascades framework where the individuals disregard their private information to follow others. We show that information cascades are relevant both for buy-side herding and sell-side herding. Short-selling restrictions may reinforce the herding behaviour since informed investors may not be able to clear out potential price misalignments.
