Analysis of the influence of fundamental and external factors on stock prices in mining sector companies listed on the Indonesia stock exchange

This study aimed to determine the effect of liquidity ratios (LR), solvency (DER), profitability (ROE), valuation ratios (PBV), inflation, and interest rates on stock prices of mining sector companies listed on the Indonesia Stock Exchange (IDX). The research sample is 41 mining sector companies with a research period from 2015-2019. The results show that the liquidity ratio (CR) and solvency (DER) have no significant effect on stock prices of mining sector companies in 2015-2019. The variable profitability (ROE), valuation ratio (PBV) was concluded to have a significant positive effect on stock prices of mining sector companies in 2015-2019. Meanwhile, inflation and interest rates have a significant adverse effect on stock prices of mining sector companies in 2015-2019.

Price extremes and asymmetric dependence structures in stock returns: the emerging market evidence

PurposeEquity research in experimental psychology reveals investors' overreactions to bad news events. This study of asymmetric price structures in equity markets investigates whether such behavior predicts stock returns in an emerging market of India.Design/methodology/approachThe research decomposes Bombay Stock Exchange (BSE) Sensex returns into Extremely Positive Returns (EPR) and Extremely Negative Returns (ENR) based on extreme values at first and then tests their lead–lag relations.FindingsThe empirical finding is consistent with the existing evidence of asymmetric news effects on stock returns in India. In precise, ENR robustly predicts one-month-ahead EPR for the sample period from January 1991 to March 2020. This predictive power persists even in the presence of popular valuation ratios and business cycle variables.Practical implicationsThe paper explains the rationale of extreme value modeling in price forecasting. Investors can find additional utility gains from market cycle information while predicting extreme returns in Indian stock market.Originality/valueThe paper is unique to understand business cycle effects in extreme return reversals in emerging markets.

Stock Returns and Valuation Ratios at Sector Level in South Africa: The Regime-switch Modelling Approach

There is mounting evidence of stock return predictability based on valuation ratios across various stock markets. Most studies in this regard assume that the link between stock returns and valuation ratios is constant and linear. Yet, return predictability may vary according to the prevailing market regime. Accordingly, this study investigated whether the dividend and price-earnings valuation ratios predict returns on six sector indices on the Johannesburg Stock Exchange and whether that predictability is dependent on the prevailing market regime. The study employed a Markov regime-switching model over a sample period spanning from 1996:01 to 2018:12. The results showed that in most sectors, predictability was present, and its significance was dependent on whether the market was in a bullish or bearish regime. These findings are useful to investors who use valuation ratios to predict returns and adjust portfolios in various sectors across different market regimes on the South African market.

Equilibrium Asset Pricing in Directed Networks

Directed links in cash flow networks affect the cross-section of risk premia through three channels. In a tractable consumption-based equilibrium asset pricing model, we obtain closed-form solutions that disentangle these channels for arbitrary directed networks. First, shocks that can propagate through the economy command a higher market price of risk. Second, shock-receiving assets earn an extra premium since their valuation ratios drop upon shocks in connected assets. Third, a hedge effect pushes risk premia down: when a shock propagates through the economy, an asset that is unconnected becomes relatively more attractive and its valuation ratio increases.

The Theory and Practice of Investor Relations: A Global Perspective

Using proprietary survey data of investor relations (IR) officers from 59 countries, we uncover new stylized facts on a wide variety of IR functions, such as the firm’s interactions with brokers and investors, the formulation of its disclosure policies, and its global outreach efforts. We find that IR activities vary widely across firms, industries, and countries. They have become increasingly important, as reflected by the more frequent involvement of IR officers with senior executives on a day-to-day basis. We also find that large and complex firms receiving greater media attention engage more in IR activities. In addition, firms domiciled in countries with weaker legal protections for investors and poorer disclosure standards, those cross-listed in the stock markets that are outperforming, and those with high global media visibility invest in greater global outreach efforts with IR activities. Firms’ IR efforts to investors worldwide are associated with higher Tobin’s q valuation ratios. We interpret our findings in the context of theories and existing evidence on the role of asymmetric information and governance problems in global markets.
