In this article I show that very basic quantitative trading strategies that generate returns from different market behaviours, when combined, can provide a more desirable and stable returns stream, as reflected in a Sharpe ratio higher than any individual strategy. We show how absolute returns can be some-what ‘sacrificed’ for an improved risk adjusted return stream, which then can be later leveraged as per the investors risk appetite. Read more
Documentation on the portfolio optimization and diversification for the open source hedge fund project
To try and maximise return the correct recipe of ingredients must be brought together. Not only do we have to look at the quality of stock selection, but the weights and quantity of stocks required for maximising returns and minimising risk. Momentum investing looks to invest in top performing stocks and combining this technique with good diversification skills and portfolio optimisation should result top performing portfolios. An added benefit is that transaction costs will be minimised if the correct stocks are picked right from the beginning as less buying and selling will have to be done in the future.
This article will aim to answer the following three questions:
- How to pick the right amount of stocks to optimize a portfolio?
- How to pick the best stocks to include in the portfolio?
- How to get the weight for each stock in the portfolio right?
It is nearly impossible to get the right mix of stocks to achieve maximum returns. A lot of time and effort has been spent trying to renovate and build upon old theories in order for investors to gain maximum returns. Wouldn’t it be ideal to be able to invest in stocks that are increasing in price and will continue to increase into the future? How much more would it benefit investors to know the right moment in which to shift stock weights i.e. buy or sell a stock in order to gain higher returns? These are just some of the questions that I will aim to answer.
This will be the first article in a 4 part series of articles. I will attempt to come up with a portfolio that will provide the best returns for momentum investing whilst actively managing the portfolio. In this first article I will be discussing the combination of momentum investing, portfolio optimisation and diversification and despite some researchers disagreeing with these two theories working together, most researchers agree that combination of strategies work well together and I will discuss how and why these specific strategies can work jointly. The second article will discuss the diversification method and give you an insight on how to pick the correct stocks and correct number of stocks followed by a third article that will discuss the portfolio optimisation area i.e. the risk-return tradeoff that should give the best stock selection by using normal distribution formula and other methods. The fourth article will combine all the topics previously discussed in order to formulate the ultimate model and discuss why the model should work. Read more
