<p>In this paper we analyse and show how price discovery process influence the volatility of stocks. Using a theoretical approach, our initial analysis revealed that stocks experience ‘normal’ volatility as the price move from one equilibrium price to another as part of the price discovery process. Our further analysis revealed that, due to the inefficiency of financial markets, stocks also experience transitionary volatility which occurs when the price transition from one equilibrium price to another. The implication of these analytical findings means that the price discovery volatility effects can only be reduced by improving the efficiency of financial markets. Thus, we recommended that the financial microstructure be designed in a manner that promotes the efficiency of financial markets.      </p>

I explore company characteristics which explain the difference in analysts’ recommendations for companies that were underwritten (affiliated) versus non-underwritten (unaffiliated) by analysts’ brokerage firms. Prior literature documents that analysts issue more optimistic recommendations to underwriting clients of analysts’ brokerage employers. Extant research uses regression models to find general associations between recommendations and financial qualities of companies, with or without underwriting relationship. However, regression models cannot identify the qualities that cause the most difference in recommendations between affiliated versus unaffiliated companies. I adopt uplift random forest model, a popular technique in recent marketing and healthcare research, to identify the type of companies that earn analysts’ favor. I find that companies of stable earnings in the past, higher book-to-market ratio, smaller sizes, worsened earnings, and lower forward PE ratio are likely to receive higher recommendations if  they are affiliated with analysts than if they are unaffiliated with analysts. With uplift random forest model, I show that analysts pay more attention on price-related than earnings-related matrices when they value affiliated versus unaffiliated companies. This paper contributes to the literature by introducing an effective predictive model to capital market research and shedding additional light on the usefulness of analysts’ reports.

Yat?r?m f?rsatlar?n?n de?erlendirilmesi süreci beklenen getiri ve riskin ölçümüne ba?l?d?r. Finansal Varl?klar? Fiyatlama Modeli (FVFM), çok uzun y?llard?r modern finans teorisinin temel ta?lar?ndan bir tanesini olu?turmaktad?r. Model, varl?klar?n beklenen getirisi ve sistematik riski aras?ndaki basit do?rusal ili?kiyi ortaya koymaktad?r. Model halen, sermaye maliyetinin hesaplanmas?, portföy yönetiminin performans?n?n ölçülmesi ve yat?r?mlar?n de?erlendirilmesi amac?yla kullan?lmaktad?r. FVFM’in çekicili?i, beklenen getiri ve risk aras?ndaki ili?kinin ölçümlenmesi konusundaki güçlü tahmin yetene?inden gelmektedir. Bununla birlikte modelin bu yetene?i 30 y?l? a?k?n bir süredir akademisyenler ve uygulamac?lar taraf?ndan sorgulanmaktad?r. Tart??malar büyük ölçüde ampirik düzeyde gerçekle?tirilmektedir. FVFM’in ampirik düzeydeki problemleri, çok say?da basitle?tirilmi? varsay?m? içermesi nedeniyle teorik hatalard?r. Çok say?daki gerçekçi olmayan varsay?m modeli pratik olarak kullan??s?z hale getirmektedir. Model ile ilgili temel ele?tiriler ise risksiz faiz oran?, pazar portföyü ve beta katsay? üzerinde yo?unla?maktad?r. Bu çal??mada, modelin varsay?mlar? ve temel bulgular?n?n yan? s?ra uygulamas?na yönelik yap?lan ele?tiriler ele al?nacakt?r.

Etkin Piyasalar Hipotezi ve Davran??sal Finans, finansal literatürün kar??t argümanlar? savunan iki temel modelini olu?turmaktad?r. Bunlardan ilki yat?r?mc?lar? rasyonel olarak kabul ederken di?eri ise yat?r?mc?lar? normal olarak ifade etmektedir. Etkin Piyasa Hipotezi’ne göre piyasalar bilgisel olarak daima etkindir. Hisseler en nihayetinde denge fiyat?na ula?acakt?r. Ya?anan finansal krizler ise k?sa dönemli düzeltme hareketleridir. Davran??sal finans, alternatif bir model olarak geli?tirilmi?tir. Buna göre yat?r?mc?lar farkl? bilgilere farkl? zamanlarda ula?maktad?r ve onlar? farkl? de?erlendirmektedir. Yat?r?m kararlar? psikolojik ve duygusal faktörlerden etkilenmektedir. Yat?r?mc?lar?n makine olarak görülmesi kabul edilemez. Davran??sal finans çok daha yeni bir konumdad?r ve çok say?da yeni çal??maya ihtiyaç duymaktad?r. Bununla birlikte iki teori aras?ndaki çat??ma yeni finansal krizlerin önlenmesi aç?s?ndan çok önemlidir. Yak?n gelecekte teorilerin kar??t olmaktan ziyade tamamlay?c? olarak kullan?lmas? beklenmektedir.   

Over the past fifty years, economic growth in emerging markets has been supported by investments in capital and technology from the developed world. The benefit of this development for the emerging markets, as measured by growth in income, employment, and wealth, is immediately apparent. There have also been significant advantages for the developed world through opportunities for higher risk adjusted returns from investments in emerging markets. This study explores the benefits of the diversification of global government bond portfolio, and provides complete performance evaluations of DMs with or without South Africa emerging market (SAEM) bonds. The study examines the benefits of inclusion of SAEM bonds in DMs, the degrees of financial integration among the research markets, the relative bond returns of dynamic factor models with time-varying coefficients and the robust tests of bond portfolio performance between DMs with SAEM and bond index. The results of this study provide important implications for global investors by identifying diversification gains in SAEM.

<p>The paper concentrates on value and size effects in country portfolios. It contributes to academic literature threefold. First, I provide fresh evidence that the value and size effects may be useful in explaining the cross-sectional variation in country returns. The computations are based on a broad sample of 66 countries in years 2000-2013. Second, I document that the country-level value and size effects are indifferent to currency conversions. Finally, I introduce an alternative macro-level Fama-French model, which, contrary to its prototype, employs country-based factors. I show that applying this modification makes the model more successful in evaluation of funds with global investment mandate than the standard CAPM and FF models.</p>

The competence of a financial system is entirely depending upon the stock market efficiency. The gradual growth of equity investor’s participation is inevitable to enrich the overall growth of emerging economies.Hence the necessity is felt to provide an empirical support to the investing community. For the purpose, this study attempts to examine the weak-form efficiency of Indian stock market – National Stock Exchange (NSE). The study has used the daily closing price of the Nifty fifty stocks from 3rdJanuary 2011 to 24thApril 2015. To test the weak form efficiency both parametric and non-parametric tests called Autocorrelation, Augmented Dicky Fuller test, and Runs Test were performed.  The study reveals that 39 stocks of NSE-Nifty Fifty are found to be weak form inefficient, so that the investors can formulate trading strategies to gain abnormal returns. The Index and 10 stocks are found to be weak form efficient during the study period since the price series found to be autocorrelation existence.

The Chinese stock market is an emerging market that has gained much importance over the past few decades. Because of this, it also serves as a great subject for studying market inefficiencies and anomalies. In this paper we provide a review of evidence regarding the development, efficiency and integration of the Chinese stock market. In particular, we review recent literature in the areas of market segmentation, cross-listings and calendar effects. This provides evidence of market inefficiency in China. We also pose questions that can be answered in future studies.

The study investigated the operational efficiency of the Nigerian stock market between 1986-2010. This was necessary given the degree of thinness of the market.  The objectives of the study were: to investigate the extent to which the operations of the market have contributed to the growth of the Nigerian economy and also to determine the functionality of the market. To achieve these objectives  data were gathered on some capital market indicators from the stock exchange factbook  of various years on market capitalization (MCAP), all share index (ASI) volume of transaction (VOLT) value of transaction (VALT) and number of listed companies (NLC) on the stock exchange.  The data were tabulated, analyzed and tested using the ordinary least square statistical technique. Findings resulting from the test of data showed that NLC, VOLT, VALT, ASI and MCAP were positive and that increase in any of the above parameters  would in turn cause an increase in the growth of the Nigerian economy at five and ten  percent levels of significance.  It further showed that  the market was operationally weak form efficient. It was therefore recommended that government should continue to provide better macro-economic environment for the private sector to lead the economy on the part of sustainable growth and development.

The paper concentrates on the value premium across countries and contributes to the investment and asset pricing literature in three ways. First, I provide fresh evidence that the high-value countries perform significantly better than the low-value countries. Additionally, this phenomenon is indifferent to the choice of the computational currency, representative index or value indicator. Second, I demonstrate that the value effect can be successfully amplified by combining with country-level size and momentum effects. Third, I show that returns to the high-value countries deteriorate in financial crisis conditions, because the country-level value premium is negatively correlated with the credit spreads, TED spread and expected volatility. I examine data from 66 markets between years 2000 and 2013.

The objective of this study is to assess the share price reactions to smoking ban fatwa on Indonesia tobacco’s company. We expect that the smoking ban fatwa in the world’s largest Muslim population will hit the tobaccos industry revenues, lower tobacco’s company profit and eventually affect the share price of those firms. We use event study methodology and standard market model to calculate abnormal returns of the tobacco’s firms related to the news of smoking ban fatwa. Our study failed to find a statistically significant effect of smoking ban fatwa on tobacco’s firm stock market return. It suggests that the investors do not see the fatwa as a factor that may control the tobacco consumption in Indonesia – thus it may not affect the tobacco’s firm revenues and profit in the future

The puzzling momentum strategies’ payoffs are defying the rational financial theory asserting the stocks returns’ unpredictability. Moreover, the momentum effect persist the main stocks returns’ anomaly escaping any risk-based explanation. The resilience of this phenomenon had favoured the development of behavioural financial field, which breaks with the investor’ full rationality hypothesis. This paper attempts to reconcile between the rational and behavioural financial theories, through the introduction of the progressive rationality concept. Especially, we argue that recognizing the temporary inappropriate investors’ reactions; can resolve the puzzling momentum anomaly.  To fulfil our objective, first we correct the monthly returns inherent to 56 stocks listed on the Tunisian stocks market from January 1998 to December 2011, from the related serial autocorrelations involved by the investors’ over and under reactions. Then, we examine the 6/6 momentum strategy’ excess returns before and after the monthly returns serial autocorrelations’ corrections. The result show that the momentum strategy is still profitable but no longer puzzling, since the related excess return is henceforth fully captured by a ? and a size effect..
