Financial Theories and Strategies Introduction Financial theories are the building blocks of today's corporate world. "The basic building blocks of finance theory lay the foundation for many modern tools used in areas such asset pricing and investment. Many of these theoretical concepts such as general equilibrium analysis, information economics and theory of contracts are firmly rooted in classical Microeconomics" (Oaktree, 2005) This paper will define and discuss five financial theories and how they impact business decisions made by financial managers. The theories will be the Modern Portfolio Theory, Tobin Separation Theorem, Equilibrium Theory, Arbitrage Pricing Theory (APT), and the Efficient Markets Hypothesis. Modern Portfolio Theory (MPT) The Modern portfolio theory {MPT}, "proposes how rational investors will use diversification to optimize their portfolios, and how an asset should be priced given its risk relative to the market as a whole. The basic concepts of the theory are the efficient frontier, Capital Asset Pricing Model and beta coefficient, the Capital Market Line and the Securities Market Line. MPT models the return of an asset as a random variable and a portfolio as a weighted combination of assets; the return of a portfolio is thus also a random variable and consequently has an expected value and a variance. Risk in this model is identified with the standard deviation of portfolio return. Rationality is modeled by supposing that an investor choosing between several portfolios with identical expected returns will prefer that portfolio which minimizes risk." (Wikipedia, 2005) Figure 1 and Figure 2 are examples on how this theory can be illustrated on a graph. Using the Modern Portfolio Theory, overtime risk assets will provide a higher expected rate of return, as compensation to the investors for accepting a high risk. The high risk will eventually lower collecting asset classes to the portfolio, thus reducing the volatile risk, and increasing the expected rates of return. Furthermore the purpose of this theory is to develop the most optimal investments portfolio which would yield the highest rate of return while ascertaining the risk for the individual or corporate investor. This theory impacts global and domestic financial managers by basing their portfolio using capital market line, capital asset pricing, and securities as a foundation for investments. When used, the MPT establishes investment portfolios, which are used by companies such as Fidelity or Scott Trade for both long-term and short-term strategies.

As stated earlier, managers are constantly faced with uncertainty, which is something many economic models do not account for. In microeconomics for instance, theory assumes that the competitive firm knows the price at which it will sell the product it produces. However, from the decision to produce, to the time of production and to the actual sale there might be a delay. Therefore the price of the product at the time of selling might differ substantially from what was expected (Markowitz. , 1991). According to Markowitz, this uncertainty cannot be dismissed, simply because if managers and investors could predict the future, they would place all their money on one investment – the one with the highest return. With this in mind, Markowitz developed portfolio theory, in which he proves the value of diversification as it reduces uncertainty.
The CAPM first began in 1952 by Harry Markowitz and his paper rigorously described the aspect of portfolio risks. A portfolio risk is when a stockholder or an investor invests in so many assets so that the rate of a risky turnover is spread amongst the assets to reduce the percentage of loss returned on the assets. For example, Mr. A buys 10 different assets from different companies so that if asset A from Alek corporations fail, Mr. A can still get returns from the 9 other assets, hence his risk and loss has been shared amongst his invested assets.
...al portfolio based on risk preferences, personal constraints and investment objectives following the Mean-Variance Theory. We have applied a CPPI strategy to allocate assets dynamically over-time and highlighted its superiority compared to the Market and Benchmark Portfolios. We have used both classical (e.g. Sharpe Ratio) and advanced performance measures (e.g. T2, Omega Ratio). We have identified that much of the portfolio’s performance can be attributed to the Selection Effect. The significant MoM indicates the presence of Momentum Effect in the portfolio’s returns. We have highlighted the contribution of Omega Ratio in modern portfolio management because of its ability to capture Higher Moments. Overall, we conclude that insurance strategies, such as CPPI, can be quite useful when investors seek insurance against rapid falls in the market and crash in equities.
In the following essay I will be comparing and contrasting the effectives of capital asset pricing model (CAPM), Arbitrage Pricing Theory, and the Fama-French three factor model when estimating the cost of capital and explaining performance of investment portfolios.
Portfolio Theory is not only used for budgeting, but is also used in investment strategies. Financial advisors create portfolios optimized to provide a certain rate of return at a certain level of risk. These portfolios can be comprised of a variety of financial instruments, like stocks, bonds, or mutual funds. In essence, the theory allows a client to build something to their specifications depending on how ag...
Considering the importance of this, Yale’s investment Committee reviewed its portfolio at least once a year. In order to decide the target allocation, the organization performed a mean-variance analysis of the expected returns and risks and compared them with those of past Yale allocations and the current mean allocation of other universities. Moreover, the organization also examined the long-run implications of its allocation for the downside risk to the

The economic rationality assumption has given an important connation for the market efficiency, as it has been the base to carry out the construction of the modern knowledge in standard finance. Resulting in the development of the most important insights in finance, such as arbitrage pricing theory of Miller and Modigliani, the Markowitz portfolio optimization, the capital asset pricing theory of Sharp, Lintner and Sharp and the option-pricing model of Black, Scholes and Merton (Pompian, 2006 and Lo, 2005). At this stage, these advances provide a sophisticated mathematical approach to explain what happen in real life. As a result, of these advances, individuals who trade stocks and bonds use these theories under the assumption that the assets they are investing in have similar value to the prices they are paying. This way, according to the market efficiency, current prices reflect all relevant information so trading stocks in an attempt to exceed the benchmark or to produce returns above average will not be possible without taking risk above the average since with arbitrage would make go back prices to their real or fundamental value (Malkiel, 2003).
Capital Asset Pricing Model (CAPM) is an ex ante concept, which is built on the portfolio theory established by Markowitz (Bhatnagar and Ramlogan 2012). It enhances the understanding of elements of asset prices, specifically the linear relationship between risk and expected return (Perold 2004). The direct correlation between risk and return is well defined by the security market line (SML), where market risk of an asset is associated with the return and risk of the market along with the risk free rate to estimate expected return on an asset (Watson and Head 1998 cited in Laubscher 2002).
In conclusion, Modern Portfolio Theory and Financial Engineering have been great financial models that helped investors all around the world. However, they have been associated with some crisis because of their assumptions. Generally, financial models assume in order to simplify the reality, so most of the time the assumptions should work. The article described each models and the roles they played in financial crises as well as some best practice of them in the future.
According to Investopedia (Asset Allocation Definition, 2013), asset allocation is an investment strategy that aims to balance risk and reward by distributing a portfolio’s assets according to an individual’s goals, risk tolerance and investment horizon. There are three main asset classes: equities, fixed-income, cash and cash equivalents; but they all have different levels of risk and return. A prudent investor should be careful in allocating each asset class to his portfolio. Proper asset allocation is a highly debatable subject and is not designed equally for everybody, but is rather based on the desires and needs of the individual investor. This paper discusses the importance of asset allocation, the differences and the proper diversification within the portfolio.

Our understanding and the concept of investment in behavioural finance combines economics and psychology to analyse how and why investors make final decision. As an investor one’s decision to invest is fully influence by different type of attitudes of behavioural and psychological ( Ricciardi & Simon, 2000). Yet, in order to maximize their financial goal, investors must have a good investment planning. Furthermore , to gain a good investment planning , there must be a good decision making among investors. They have to choose the right investment plan I order to manage the resources for different type of investments not only to gain profit wise but also to avoid the risk that occur from investment.
