. Harry Markowitz established the foundation of modern portfolio theory in 1952.
One of the most valuable concepts in the strategic management of multi-divisional companies was portfolio theory in New York. In the previous decade Harry Markowitz and other financial theorists developed modern portfolio theory. They concluded that a broad portfolio of financial assets could reduce specific risk. In the 1970s marketers extended the theory to product portfolio decisions and managerial strategists extended it to operating division portfolios. Each of a company's operating divisions were seen as an element in the firm's portfolio. Each operating division was treated as a semi-independent profit center with its own revenues, costs, objectives and strategies.
The modern portfolio theory was developed by Harry Markowitz in 1952. His work revolutionized the field of finance by introducing the concept of diversification and the importance of balancing risk and return in investment portfolios.
Investment theory is a framework that seeks to understand the principles and factors that influence how individuals and institutions make decisions about allocating financial resources in order to achieve certain financial goals. It includes concepts like risk and return, diversification, and asset allocation.

Accounting theory examines practical and theoretical issues in accounting practices such as historical costs, decision usefulness, portfolio risk, fair-value-oriented standards and executive management compensation and earnings. In addition, it also discusses economic and political issues and criteria related to accounting practices required by accounting governing bodies such as Canadian Institute of Chartered Accountant (CICA), Financial Accounting Standards Board (FASB) and International Accounting Standards Board (IASB). The first goal of accounting theory is to describe and explore various theories that underlie financial accounting and reporting. The second goal is to explain and illustrate the relevance of these theories in order to understand the practice of accounting and reporting. Some of the main theories are based on economics and finance. For instance, by discounting future cash flows to present time, the present value model enables a theoretically correct basis of asset and liability valuation and income measurement of a firm. Thus, the present value model provides a benchmark to guide accounting practice. From a finance stand point, portfolio and efficient market theory are used in accounting practices in understanding how investors make rational investment decisions and how they use financial accounting information to make their decisions. Accountants can then prepare financial statements that are of greatest use to investors. To put in a nutshell, accounting theory helps to understand the impact of complex ideas and regulations on financial reporting and the interpretation of information generated by financial reporting at the conceptual level.
The contagion theory suggests that financial crises spread rapidly across markets or countries due to panic and herding behavior among investors. On the other hand, the convergence theory posits that countries or financial markets become more similar over time as they adopt similar policies, regulations, or market practices.
