Equity Risk and Return across Hidden Market Regimes

The key to understanding the dynamics of stock markets, particularly the mechanisms of their changes, is in the concept of the market regime. It is regarded as a regular transition from one state to another. Although the market agenda is never the same, its functioning regime allows us to reveal the logic of its development. The article employs the concept of financial turbulence to identify hidden market regimes. These are revealed through the ratio of the components, which describe single changes of correlated risks and volatility. The combinations of typical and atypical variates of correlational and magnitude components of financial turbulence allowed four hidden regimes to be revealed. These were arranged by the degree of financial turbulence, conceptually analyzed and assessed from the perspective of their duration. The empirical data demonstrated ETF day trading profits for S&P 500 sectors, covering the period of January 1998–August 2020, as well as day trade profits of the Russian blue chips within the period of October 2006–February 2021. The results show a significant difference in regard to the market performance and volatility, which depend on hidden regimes. Both sample data groups demonstrated similar contemporaneous and lagged effects, which allows the prediction of volatility jumps in the periods following atypical correlations.

Banks as Regulated Traders

Banks use trading as a vehicle to take risk. Using unique high-frequency regulatory data, we estimate the sensitivity of weekly bank trading profits to aggregate equity, fixed-income, credit, currency and commodity risk factors. Our estimates imply that U.S. banks had large trading exposures to equity market risk before the Volcker Rule, which they curtailed afterwards. They also have exposures to credit and currency risk. The results hold up in a quasi-natural experimental design that exploits the phased-in introduction of reporting requirements to address identification. Heterogeneity and placebo tests further corroborate the results. Counterfactual stress-test analyses quantify the financial stability implications.

Profits to opportunistic insider trading before and after the Dodd-Frank act of 2010

Purpose The authors examine if opportunistic insider trading profits decrease after the enactment of the Dodd-Frank Act (DFA) in 2010. The DFA expands legal prohibitions on insider trading in the USA. Design/methodology/approach The authors identify opportunistic insider trades following a method that is outlined in Cohen et al. (2012). The authors examine univariate statistics and perform multivariate regression tests to examine opportunistic trading profits before and after the DFA. Similar multivariate regression tests have been used widely in the literature to examine the profitability of insider trades. Findings The authors find that opportunistic insider purchases were highly profitable before the DFA. Profits after opportunistic purchases were significantly lower after the DFA. Opportunistic insider sales were contrarian trades both before and after the DFA. However, share prices kept increasing after insiders sold their shares. Originality/value To the best of the authors’ knowledge, the paper is the first study that compares the profitability of opportunistic insider trades, as identified by Cohen et al., before and after the DFA. The study contributes to the literature that finds that insiders change their strategic trading behavior when the potential costs of the illegal trading increase due to regulatory action.

Do algorithm traders mitigate insider trading profits?: Evidence from the Thai stock market

This paper asks whether algorithm traders (AT) mitigate insider trading profits in the Thai stock market over the period of 2010–2016. We find that in general it does but not in the case of buy side, big trades nor the executive trades. Our findings suggest that, to some extent, AT can take important role to increase an efficiency in stock market by processing the public information and incorporating it into price at ultra-fast speed. Additional robustness checks based on the instrumental variable approach confirm our findings.

10. Taxation of sole proprietors and partnerships

Sole traders and partners are liable to pay income tax on their income in accordance with the Income Tax (Trading and Other Income) Act 2005 (ITTOIA). This chapter discusses income tax liability of sole traders and partners; calculating the trading profits; capital gains and capital losses; trading losses; basis of assessment; capital allowances; and changes in a partnership.

21. Capital allowances

This chapter discusses the capital allowances system. Most businesses will need to acquire fixed assets for their operations, nearly all of which will depreciate in value over time due to wear and tear. While this depreciation may not be deducted from the business’s trading profits, certain limited types of fixed asset entitle a business to claim relief in the form of a capital allowance, which can be deducted when calculating taxable profits. The purpose of this allowance is to give tax relief for the depreciation in value of specific assets bought and owned for business use, by allowing the owner to write off their cost against the taxable income of the business. The amount to be written off is calculated using a fixed formula. Relief is only available if the capital expenditure has been incurred in respect of the items of expenditure prescribed by the Capital Allowances Act 2001.
