Answer 1: An investment fund that is based on the current trends is known as a momentum fund. The trends that are usually observed include trends of price movements and earnings. Thus, the managers invest in the companies that have positive momentum, and they may also sell the stock of the companies that have negative momentum. Further, individuals must invest in such type of fund as these funds contain high probability of fetching high return investments. However, there is an important point to understand that these funds require a high level of monitoring because the directional changes might occur during the period and also the momentum factors can be of short-term.They consider different characteristics of a stock, thus end up with an informed investing decision. The most common factors which are considered while analysing either to invest in the momentum fund or not include earnings, price movement, and revenue. The investors must utilise the benefits offered by the momentum investing by investing in these funds. There are various other companies which offer such type of investing. However, AQR is the most suitable option available to the investors at the moment. AQR was established in 1998 and has grown rapidly over the years. After the company entered into the mutual fund market, it focused on financial advisor channel. It developed three separate long-only momentum indexes over the years and operated through them. These indices are known as a small-cap momentum index, a large-cap momentum index and a large-cap international momentum index. The company possesses a “back-test” to demonstrate its investors that the momentum strategies offer strong performance potential.However, there are also certain risks which such momentum funds contain that must be in the knowledge of the investors. They must understand those factors which are being considered while constructing a portfolio. For instance, there are funds that only focus on the past performance of the company and others that not only follow the performance momentum but also consider the expectations for the future as well.Answer 2: Yes. The ties work in both cases. Research studies suggest that social networks provide easy accessibility to the resources, information and allow sharing and coordination. Thus, those who have strong connections and are socially active they are in a better position relative to those investors who do not have such connections. It is because the social connections regulate the behaviour of the society. They influence the behaviour by affirming or negating them. Further, it is easier to verify the information in the social networks. These social relations thus can help an organisation to get the benefits by seeking an adequate level of financing. This notion can be well explained by the embeddedness approach; this concept explains that why economic transactions become embedded in social relations and thus affect differentially the valuation and allocation of the resources. Further, there has been a debate that due to efficient market hypothesis stock returns cannot be predicted (Hong, 1999). However recent studies show that information is a major factor that has a potential to influence stock returns (Qian, 2007). Also, that the information contained through social media reaches to a broad audience (Risius et al., 2015).However, there are negative implications of such social connections as well. For instance, these social connections also contain the probability of restricting the actions by imposing the normative behaviour. Moreover, a gradual Information flow model highlights that the contemporary world differs in two different ways as assumed by the EMH. Firstly, some information is restricted as private and is not available to the public. Secondly, even if the information is disclosed to the investors, their cognitive biases tend to limit their ability to perceive the information (Sul & Yuan 2017).Research studies on momentum trading have shown the consensus on the point that in the intermediate horizon where the period remains between three to 12 months the stock returns show persistence in generating returns. However, the reasons for such persistence may differ. It depends on the factors which are at the core of the momentum funds and which are kept under consideration while formulating such funds. There are also considerations regarding a view that associate abnormal returns with the momentum strategies and suggest that these momentum strategies fetch abnormal returns as a compensation for the unidentified source of non-diversifiable risk (Carhart, 1997). Further, studies also suggest that the earning related new also play a significant role in the price momentum trading (Burch, 2002). This study also strengthens the notion of social connectedness as well. Social connectedness also affirms the theory of efficient market hypothesis. Thus when the information is available to all the investors than the tendency, inclination and the probability to buy such funds increases. It is very important to know that what type of information that is being rotated in these social networks as it works vice versa as well.Research studies suggest that the naïve investors may also cause the momentum with biased expectations (Hvidkjaer, 2009). It has also be studied that individuals may use heuristics or cognitive biases cause them to suffer. That is the reason these individuals rely on particular models of risk and expected return. Thus by these models, investors tend to buy or sell the same securities at the same time. To conclude, the cognitive biases of the individuals and prices tend to formulate the behaviours of the individuals. This is linked to the social connected as well. In an environment of increased networking and social connected such factors contain the probability of creating negative ties. Thus, It is very important to understand about the behavioural disposition of the abnormal returns that either they are due to the proposed explanation of the behaviour or they are caused by the rational motivations. Thus the social connectedness works at both ends.Social impacts of the fund relate the effect caused by trading in these funds over the society. Literature review exhibits that social impact investment brings bring positive changes in the lives of the beneficiaries in multiple spectrum of life. Such as social, political, health and wealth (Vanclay, 2003). Further, such social impact investments are made with an intention to cause a visible and measurable social impact which can also provide the financial upside. In the case of momentum funds, there are studies which assert that reliance on momentum funds may make people feel uncomfortable. The reason behind this is that the momentum effect refers to the propensity with which the relative winning stocks kept on winning, and the losing stock kept on losing. However, this tendency can be curbed by the investors by adopting the mechanistic momentum strategies. Further, momentum trading does not put much emphasis on the fundamentals of the company thus is saved from redeeming the social merit as well. It puts more emphasis on the value of the company.Moreover, the social impact contains different dimensions thus it is difficult to measure the social impact by single metrics universally. However, there are two approaches which can assist in the measurement of social impact. One method through which the social impact can be measured it it is the comparison of anticipate social benefits which are incurred against the costs. The other method is the theory of change. This method cause to explain the process through which the positive social impact has been created.To sum, the social connections play and important role in increasing importance and potential of a fund among the public so that individual investors may look forward to investing in it. The impact of such an impact can be measured by looking at the trends, and the behaviours of the people towards the fund of that are being offered. Research studies suggest that social ties and networks play a significant role in the financial contexts and a broader sense they also influence the decisions and outcomes of the managers and directors (Bertrand and Schoar, 2003; Xuan, 2009).Answer 3:The strategy of AQR and the tradition index funds differ in the following areas. Firstly, the traditional strategies may sell the stocks which might produce losses to maximize returns however the stock under the momentum strategy only are those that bring profitability and are termed as winner stocks. Secondly, AQR being an open-ended mutual fund requires maintaining liquidity so that it shall be in a position to return the funds to the investors when they demand in the future while the other funds can require a lock-up period and also may require a notice period to repay the amount back to the investors. Finally, the strategy required by the regulators by AQR tends to be well diversified. The company estimates the risk and return dynamics on a regular basis.Moreover, the company offered the hedged funds to the mutual investors and the mutual funds to all the investors. Thus, these funds, where on hand can outperform the other indexes, they also contain the probability that in case of wrong decisions they might cause increased costs and eliminate their appeal to the investors which is not the case with the other indexed funds.Lastly, there are costs associated with the implementation of actual momentum strategies. Research studies suggest that there is information available on the stock returns and the observable variables. Also, the information regarding the known variables such as ration to price/book and the changes in the prior prices is also available. However, the findings regarding the distinction between the realisable returns and the returns to the simulated strategies are often not available. The evidence related to size and value is available, but this is not the case of momentum trading.Answer 4: Momentum fund theory as defined by AQR suggests that it is a phenomenon which says that the stocks shall perform well in the future as well as it has performed in the past as compared to the other winner stocks and vice versa. Further, the relative performance is the key factor in the study of momentum theory as it suggests that a strategy shall be implemented without considering the ups or downs of the market. This keeping this view in mind along with the fact that there is a neglected firm effect as well plays important role in the application of momentum stocks. As per the concept of neglected firms, it states that those firms which are lesser publically known firms bring more abnormal risk-adjusted returns on their stocks. The concept is affirmed by the literature where many investors believe that the strategies that are easily explained for instance like momentum strategies lost their efficacy by the time they became known by the majority of the people. Moreover, the impact of social connections cannot be ignored in this regard. That plays an important role in disseminating the information whether good or bad and ratifying the validity of the momentum fund by any company. Thus, It can be concluded that if such factors remain constant the things shall work smoothly, however, on the other hand, the theory contains the probability of negating itself.Research studies argue that the momentum in the prices of the stock reflect the manifestation of the behaviour in a trade by the market participants. These participants condition the trade on the basis of prior price movements. For instance, positive feedback strategies help them to fetch the results they aspire. The behaviour manifested by such trading violates the usual norms of rationality narrated by the Efficient Market Hypothesis. A number of studies have also attempted to fit this model in the frame of behaviours offered by the psychological paradigms. They attributed the patterns of investor trading either as an under-reaction or as an over-reaction while matching them to the perceived information obtained prior to the price movements.To illustrate the effect caused by the momentum trading to the stock returns Jegadeesh and Titman (1993) formed an equal-weighted portfolios and based these on the deciles of ranking by all NYSE and AMEX stocks. These stocks were based on the prior-j-month return. By j-month, that means 3, 6,9 and 12. The period of analysis was taken as 1965 to 1989. According to this scenario, the strategy bought 10 stocks (winners) and sold 1 stock (loser). The profit was the net return manifested in the long short-position as measured over the holding period mentioned above. The portfolio holdings began after 1 month of the portfolio creation. The purpose of this was to avoid any sort of micro-structure effects caused in the returns. The trading showed inconsistent results and the profits ranged from 0.69% to 1.49%. This reflects the inconsistency which may be caused by such funds negating their theory on which they are based. Further, in this illustration, one important point of consideration was that the stocks that the portfolio contained were not changed during the period of portfolio holding, also that the portfolios were rebalanced to the equal weights every month.ReferencesBertrand, M., Schoar, A., 2003.
