Security Analysis and Portfolio Management Assignment Help & Online Tutoring

Security analysis estimates what individual shares and bonds are worth, through fundamental or technical analysis. Portfolio management combines securities so the overall risk and return suit the investor's objectives. The subject links them, since a security's contribution to portfolio risk matters more than its own volatility.

Fundamental analysis estimates intrinsic value from economic, industry and company information, expecting price to converge on it. Technical analysis studies price and volume patterns, assuming past behaviour carries information about future moves. The two rest on different and largely incompatible assumptions about markets.

Intrinsic value is what a security is worth based on the cash flows it is expected to generate, discounted at a required rate of return. It is compared with market price to judge whether a security is overvalued or undervalued, and it depends heavily on the inputs assumed.

The dividend discount model values a share as the present value of expected future dividends. In its constant growth form, value equals next year's dividend divided by the required return minus the growth rate. It requires growth below the required return to give a meaningful answer.

The capital asset pricing model gives the required return on an asset as the risk-free rate plus beta multiplied by the market risk premium. It prices only systematic risk, on the reasoning that diversifiable risk can be removed at no cost by holding a spread of assets.

Beta measures how much an asset's return moves with the market. A beta of one moves with the market, above one amplifies market moves, and below one dampens them. It is estimated from historical data by regression, so it is an estimate rather than a fixed property.

Systematic risk affects the whole market, from interest rates, inflation or economic cycles, and cannot be diversified away. Unsystematic risk is specific to a company or industry and can be largely removed by diversification, which is why only systematic risk is priced in CAPM.

Combining assets whose returns do not move together means poor outcomes in one are often offset by better outcomes in another. Portfolio standard deviation then falls below the weighted average of the individual ones, and the lower the correlation, the larger that reduction.

The efficient frontier is the set of portfolios giving the highest expected return for each level of risk. Portfolios below it are inefficient, because a better return is available at the same risk. Investors choose a point on it according to their risk tolerance.

The efficient market hypothesis holds that prices already reflect available information. The weak form covers past prices, the semi-strong form all public information, and the strong form private information too. Each form, if true, undermines a different approach to beating the market.

The Sharpe ratio divides a portfolio's return in excess of the risk-free rate by its standard deviation, giving return per unit of total risk. It is appropriate when the portfolio represents the investor's entire holding, so that total risk rather than market risk is what matters.

Both divide excess return by a risk measure. Sharpe uses standard deviation, so it captures total risk, while Treynor uses beta, so it captures only market risk. Treynor suits a portfolio held alongside others, where specific risk is already diversified away.

Jensen's alpha is the difference between a portfolio's actual return and the return CAPM would require for its beta. A positive alpha suggests performance beyond what the risk taken would justify, though it may also reflect luck, a missing risk factor, or a poorly chosen benchmark.

Asset allocation is the division of a portfolio between asset classes such as equities, bonds and cash. Strategic allocation sets long-term proportions from objectives and risk tolerance; tactical allocation varies them to exploit shorter-term views. Research suggests it drives most of the variation in returns.
