Pairs Trading and Buy-and-Hold Trading Algorithms

Post category:Finance Software and IT
Post published:2022-04-23

Pairs trading is an established trading strategy for hedge funds and alike. It is a relatively simple trading strategy that presents two distinctive phases. First, it identifies pairs of securities that are related using one year of historical data. Second, it trades for six months the underlaying securities of the pairs whenever the spread of the pairs exceeds certain value, usually two times the historical standard deviation. In my latest manuscript I conduct an empirical research of pairs trading algorithm to study its behaviour and fundamental characteristics. Likewise, I compare the results with the standard benchmarking Buy-and-hold strategy using SPY contact. I find particularly interesting the conclusions for retail and institutional investors

Algorithmic trading – the first year of Doctorate in Business Administration

I have successfully passed my first year of doctorate in business administration (DBA), so three more years to go. Looking backward, the experience has been rewarding, demanding, mentally stimulating but not absent of fears and existentialist crisis. My naive and candid view of algorithmic trading has grown tremendously, now I am aware of the academic research techniques that help me to understand the existing literature; I have defined and exercised the foundation of algorithmic trading, academically and practically; and I have started my first formal literature reviewing of my research interest. Curious about algorithmic trading?

The study of algorithmic trading is of high importance given its predominance and forecasted growth. In 2019 the majority of the equity traded in US was executed by algorithms, equivalent to 35.1% of $31 trillion and the global estimated compounded annual growth rate over the period 2020-2027 is 8.7%. This article evaluates three algorithmic trading strategies: buy and hold, volatility risk premium and sentiment momentum. Which one might be the best for an investor with an investment horizon of five years?

Moving from HostGator to Amazon Web Services

I've been user of "low cost" shared web hosting for many years. I started with blueHost and I ended with HostGator. The experience has not been fully satisfactory, the control panel is bulky and the work is not really smooth, however my cost analysis concluded that they were the most cost effective.

Cisium, Inc., Website Closing

It has been a very long journey for Cisium, Inc. website. It started in 2007 and this year finally I shut it down. I created the site using Joomla!, it overcome one major update in 2010. To use Joomla! as content management system has not been a pleasant job. In my experience Joomla! is slow and the administration is heavy. After many years using Joomla! in many websites, I don’t think it will use it anymore.

Bluehost, Subversion and TortoiseSVN

Subversion is a widely distributed open source version control. Almost all the information is susceptible to being controlled with versions, I will not now make a dissertation on this concept .... Subversion not only efficiently manages the version, but allows a quick and secure sharing of information between people located in different countries. I have decided to install Subversion on my commercial Bluehost server, I have it wasted: unlimited hard disk, and monumental bandwidth and I only host a few web pages.

I’m so excited, that I have decided to write a post. I was so frustrated with my contacts in my Android Phone, they don’t stop to duplicate every time I was sync using Samsung Kies and Microsoft Outlook 2010.I’m not sure who was the guilty in the duplication; I guess it was related to Samsung Kies but I’m not sure, it could be Microsoft Outlook as well, I don’t have clear evidences.

Mourning C and Unix

No doubt today I have to make a post, unfortunately because Dennis Ritchie, a person based on the gestation and development of the Unix operating system and the C programming language, has died at 70. Anyway, thank you very much Dennis for your contribution to the history of mankind, I have not used any other language like C in such a passionate and fervent way. Well lately I have to say that Microsoft's uncles have done a masterful job with C#.

The Post-PC Era?

There are numerous news that I have been hearing that we are in the post-PC era, since Steve Jobs prophesied. Mmmmh ... well among some of my qualities I am dedicated to the complete design of electronic systems based on microcontrollers, in my case lately I am designing systems based on implementations of ARM cores by NXP. These processors are called SoC, System on Chip, which means they have a lot of integrated peripherals.

Generic Embedded Platform

Obviously the heart of the system is the MCU/CPU. My approach was to find out a balance between the cheapest, most powerful, and higher trend MCU in the market. Without any doubt the winner is the AMR, many manufacturers have adopted these cores: TI, Samsung, nVidia, Intel, Atmel, NXP, Freescale, a never ending list. For a system designer like Cisium this provides a big advantage, this allows to switch between manufacturers with similar cores with a great reutilization of the knowhow.
