When constructing a multi-factor model, it is difficult to decide how many and which factors to include. Popular Courses. Tools for Fundamental Analysis. Although originally developed for the US equity market, the multifactor Xfactor models model was rapidly extended to other equity markets and to other types of securities such as bonds and equity options. Note that three different dimensions are involved here two periods, three factors, and four assets. We consider several cases in turn, Xfactor models on decomposition of returns, be they over time or over scenarios. This means that the only sources of correlations among asset total returns are those that arise from their exposures to the factors and the covariances among the factors.

IF you want to see how the reality circuit pays off, look no further than model and Celebrity Big Brother star, Chloe Khan. The brunette has in fact got an incredible rags to riches story — complete with a jaw-dropping transformation. Before searching for stardom, Chloe was a young lass from Wakefield, Yorkshire with a very colourful past and interesting fake tanning skills. By the time she appeared on The X Factor she had been arrested on numerous occasions some reports suggest over times — including when she was just 13 and crashed a car with boyfriend, Ian Hough.
Chloe got through to the bootcamp stage of the competition, but was kicked off after pulling an all-nighter to party and turning up "smelling like vodka". After her very public fall from grace thanks to X Factor, Chloe disappeared from the public eye for some time before re-emerging with a completely new look and successful business.
Gone was her bad fake tan and dodgy hair extensions - and in their place was a pair of brand new boobs, glamorous make-up and a millionaire lifestyle. We moved around a lot, and could barely afford to pay the bills. One Christmas we had beans on toast for dinner. During her time in the house, she was seen getting hot and steamy with Stephen Bear on numerous occasions - despite him having a girlfriend at the time.

The factor model equation may appear to make a significant statement about the relationship between an asset's return and the values of the enumerated factors, but this is not so. Purists will note that it is unusual to place tildes after stochastic variables rather than over them. Torre made a number of improvements to this framework which importantly sharpened the risk control achievable by these means.

For instance the model might be fit over the highest capitalization US common stocks. The primary application of the model is to estimate the asset by asset covariance matrix C of asset returns by the equation. The matrix C is then used for Markowitz portfolio construction which involves maximizing the quadratic utility function. Here a is a vector of expected returns and k is a scalar parameter termed the risk aversion. Nicolo G. Torre made a number of improvements to this framework which importantly sharpened the risk control achievable by these means.
Each asset would be given an exposure to one or more industries, e. These industry exposures would sum to 1 for each asset. Thus the model had no explicit market factor but rather the market return was projected on to the industry returns. Torre modified this scheme by introducing an explicit market factor with unit exposure for each asset. To keep the model identified by imposed the condition that the industry factor returns sum to zero in each time period. Thus the model is estimated as.
Here m t is the market return. This model provides a rapid update of market variance which is incorporated into the update of F, resulting in a more dynamic model of risk. In particular it accounts for the convergence of asset returns and consequent loss of diversification that occurs in portfolios during periods of market turbulence.
In the risk model industry factors carry about half the explanatory power after the market effect is accounted for. However, Rosenberg had left unsolved how the industry groupings should be defined — choosing to rely simply on a conventional set of industries. Defining industry sets is a problem in taxonomy. The basic difficulty is that the industry is defined by the members assigned to it, but which industry an individual equity should be assigned to is often unclear.
Difficulties can be reduced by introducing a large number of narrowly defined industries, but this approach is in tension with the demands of risk estimation. For robust risk estimates we favor a moderate number of industries with each industry representing a few percentage points of market capitalization and not exclusively dominated by the largest company in the industry. Torre resolved this problem by introducing several hundred narrowly defined mini-industries and then applying guided clustering techniques to combine the mini-industries into industry groupings suitable for risk estimation.
In the initial Rosenberg approach factor and specific returns are assumed to be normally distributed. However experience turns up a number of outlying observations that are both too large and too frequent to be fit by a normal distribution Although introduction of a GARCH market factor partly reduces this difficulty, it does not eliminate it.
Torre showed that return distributions can be modeled as a mixture of a normal distribution and a jump distribution. In the case of a single factor the mixing model is easily stated. Each time period t there is a binary mixing variable b t. Torre found that simultaneous jumps occur in factors. A transmission matrix T then maps w from the shock space into the factor space. Torre found that the market, factor and specific returns could all be described by a mixture of normal returns and power law distributed shocks occurring at a low frequency.
This modeling refinement substantially improves the performance of the model with regard to extreme events. As such it makes possible construction of portfolios which behave in more expected manners during periods of market turbulence.
One is relatively innocuous. The other is not. This is not as restrictive as it may seem. Consider, for example, a case in which the residual return is correlated with factor 1.
By adjusting the factor exposure b i1 appropriately, the correlation of the residual with the factor can be made to equal zero. Moreover, this can be done for every factor. In fact, in simple settings using historic data, multiple regression procedures can be used to find a set of factor exposures b ij 's that will give residual returns that are uncorrelated with each of the factors. Because standard linear multiple regression methods select slope coefficients here, the b ij 's that minimize the variance of the residual here e i.
But this will insure that the residual is uncorrelated with each of the independent variables here, the f j 's , since the removal of any such correlation by changing one or more b ij 's will reduce the variance of the residual.
Thus the assumption that the residual is uncorrelated with each of the factors is convenient, but does not give the linear factor model much power.
However, the second assumption does. The key assumption of a linear factor model is that the residual for one asset's return is uncorrelated with that of any other:. This means that the only sources of correlations among asset total returns are those that arise from their exposures to the factors and the covariances among the factors.
The residual component of an asset's return is assumed to be unrelated to that of any other asset, and hence totally specific to that asset. In other words, the risk associated with the residual return is idiosyncratic to the asset in question.
This assumption makes a linear factor model powerful in the sense that it rules out many possible combinations of outcomes. But greater power comes at a cost. The more restrictive a model, the greater the chance that it may be inconsistent with reality.
For this reason it is incumbent on the Analyst to try to capture the most important sources of correlations among asset returns by including a sufficient number of factors and attempting to focus on the most important ones. This being said, as in the construction of any model, parsimony is a virtue, since the goal is to include "signals" and avoid "noise". We have termed the standard factor model linear which, strictly speaking, it is. However this is far less restrictive than might first seem.
There are no restrictions on correlations among the enumerated factors, so it perfectly possible to include some that are correlated with others or are transforms of others. For example, assume that the desired relationship is a quadratic one in which r i is related to two factors, f a and f b as follows:.
In cases of this sort it may be difficult to estimate the values of the sensitivities b ij 's from historic data because the new factors are highly correlated with each other, but there is no reason why such a format cannot be employed if good estimates can be obtained.
Thus far we have imposed no restrictions on the expected returns of the factors or on the asset's residual returns e i 's. In general, we will not do so.
This allows the expected return of e i to be positive, negative, or zero for any asset. As typically written, the equation becomes:. As the choice of letter suggests, the equation is often written with the a i term first:. Factor models are used in many domains in the field of investments, so it should not be surprising that different factors are used and different terms employed to describe the key components. The b ij coefficients may be called: factor exposures, factor sensitivities, factor loadings, factor betas, asset exposures style or something else.
The e i term may be called: idiosyncratic return, security-specific return, non-factor return, residual return, selection return or something else. Different problems require different factors and emphasize different economic relationships. The job of the Analyst is to either construct and apply an appropriate factor model for the task at hand or to at least understand the underlying structures and economic meanings of models constructed by others.
A factor model is especially useful when analyzing historic asset returns, since such a model allows the Analyst to separate components of the overall return of the asset.
Models bring fashion X factor to Shrewsbury's shopping centres
A local landmark in Shrewsbury would like to hear your views. Click here. A stylish blend of fashion, music and dance brought glamour and glitz to Shrewsbury's busy Darwin and Pride Hill Shopping Centres on Saturday. The Centres played host to Pop Up Fashion with a team of four model-dancers regulars on top TV shows like X Factor and accompanied by presenter Mike Lockwood, staging a series of shows throughout the day. On a busy Shrewsbury Saturday it brought crowds flocking to be entertained by the models parading the latest High Street fashions from the centre retailers.
New Look manager Emma Bates said: ""The models were very good and the show went very well and crowds have been gathering in the centres through the day. Sam Bale, at River Island , was delighted with the event and she said: "It's been really good, very positive and it's been nice to see something different.
Tricia Grace, at Roman , said: "The models looked really good in our dresses and the show they did for us was great. It's brilliant to have events like this in the centres. Mikey Lockwood, of organisers Maynineteen, said: "It was my first time in Shrewsbury and it's a lovely town and the models were very energetic from first to last and the event went very well. Kevin Lockwood, Manager of the Darwin , Pride Hill and Riverside Shopping Centres, was also delighted with the way the day went and he said: "It was a brilliant day and it attracted a lot of attention with the centres very busy with shoppers.
The reaction from the shops has been very positive and there seemed to be plenty of smiling faces here. Skip to main content. Published on Tue, 5th May
