Love Yourself Like Your Life Depends On It

Ravikant, Kamal has written this short book where there is not a extra adjective or word so you can concentrate in the goal of the book.

For my memories some of the topics described in the book:

  • Darkness is the absence of light, any negative though is darkness.
  • How do you remove it?, do you fight, fear or worry?Do you push or drown away sadness and pain?  Doesn’t work.
  • Look for the window, pull out a rag, and start cleaning. Just clean.
  • See the light of positive things that there is outside of the window.
  • Mental loop:
    • Repeat and repeat it, like a groove in rock created by water.
  • Meditation:
    • Music, 7 – 10 minutes, “I love myself”
    • Mirrow, 5 minutes.
  • Memory: reinforce the pathways.
  • Do the exercise about the thoughts that affects to you, differenciate if they are real or not real. Identify when something is real or when the mind is hijacked.
  • Surrender: “I used the fear as energy, driving me forward, pushing to achieve, pushing to succeed, paying no attention to my body, to the present, and I paid the price“. “Often, the price for not being present is pain“.
  • Real growth comes through intense, difficult, and challenging situations.

 

 

Quantitative trading, Ernie Chang

This book contains basic concepts and approach (step by step) for does that want to initiate themselves on Quantitative trading. The focus is on statistical arbitrage trading, that deals with the simplest financial instruments: stocks, futures, and sometimes currencies.

The chapters cover the steps a trader should take:

  1. The Whats, Whos, and Whys of Quantitative Trading,
  2. Fishing for Ideas,
  3. Backtesting,
  4. Setting Up Your Business,
  5. Execution Systems,
  6. Money and Risk Management,
  7. Special Topics in Quantitative Trading, (reading it now)
  8. Conclusions.

You can follow the author blog that contains further valuable information and some nice examples.

A short list of common pitfalls related to how the back-test program is written:

  1. Survivor-ship bias: data does not contain companies that have fallen bankruptcy.
  2. Look-Ahead Bias: this phenomenon happens when you are using information that was available only at a time ahead of the instant the trade was made. For instance, “Buy when the stock is within 1 percent of the day’s low”.
  3. Data-Snooping Bias: the use too much parameters that make you build an over-optimized model. A rule of thumb: 5 parameters.
  4. Sample size: you need enough data to back test, how much? As a rule of thumb, let’s assume that the number of data points needed for optimizing your parameters is equal to 252 times the number of free parameters your model has. For instance, you define a daily trading model with three parameters, then you should have at least three years’ worth of back-test data with daily prices.
  5. Out-of-Sample Testing: divide your historical data into 2 parts. Use the first part for training, and keep the second part to test the resulting model.

PMP Certification

I passed my PMP exam this month.

I read the PMBoK, I did the virtual led training courses offered by the company I work and I did a lot of exams, reviewing concepts and learning the details of the exam reviewing answers and explanations.

There is a good bunch of exams on the internet, and the more similar ones I found to the exam I did were:

PMP Exam Prep Questions, Answers, & Explanations: 1000+ PMP Practice Questions with Detailed Solutions by Christopher Scordo (4-Nov-2009)– 1600 questions by Christopher Scordo.

Now thinking about the next certification or training course to take. Any suggestion?

Thinking, Fast and Slow

After have read The Undoing Project I was investigating about some of the books published by Amos Tversky and Daniel Kahneman. Finally I found this essay named “Thinking, Fast and Slow”.thinking-fast-slow

This psychology essay goes chapter by chapter decomposing the different ways the mind works, doing it in plain English. Chapters are short and concentrated on an specific aspect and contains very good experiments that helps you to understand the human behavior.

I can see myself reflected on this analysis

I see so many of the things on myself and I see so many of these behaviors reflected on people when I see TV advertisement, when I see people on a supermarket, when I read newspaper, etc.

Nobel Prize in Economics

In 2002 Daniel Kahneman received the Nobel prize in Economics for having integrated insights from psychological research into economic science, especially concerning human judgment and decision-making under uncertainty

Update on October 2017

Now,in 2017 Richard Thaler was awarded with the same prize thanks to his contributions done on behavioural economics.

The undoing project

This book is making me to think about some habits and false concepts we use to fall in a daily basis. There are some interesting parts of the book for re-read from time to time.

People regretted what they have done, and what they wished they hadn’t done, far more than what they had not done and perhaps should have. The pain that is experienced when the loss is caused by an act that modified the status quo is significantly greater than the pain that is experienced when the decision led to the retention of the status quo.

 

When choosing between sure things and gambles, people’s desire to avoid loss exceeded their desire to secure pain.

 

People did not chose between things. They chose between descriptions of things. Economists, and anyone else who wanted to believe that human beings were rational, could rationalize, or try to rationalize, loss aversion.

 

The endowment effect was a psychological idea with economic consequences. People attached some strange extra value to what ever they happened to own, simply because they owned it, and so proved surprisingly reluctant to part with their possessions, or endowments, even when trading them made economic sense.

 

The emotions of unrealized possibility: these emotions could be described using simple math. Their intensity was a product of two variables: the desirability of the alternative and the possibility of the alternative.

 

Man Boobs

Daryl Morey joined the Rockets as General Manager in 2006 with the idea of launching data-driven decision-making on the team. This included the draft elections.
In 2007 they already had their first model. His first choice was a 22-year-old boy who surpassed the rest in that model.
A picture of this guy was found with a baby face and a , fluffy body … and someone from the scout team nicknamed him Man Boobs.

Man Boobs here, Man Boobs there … At the end, Morey doubted and was not brave enough to push his model in front of the traditional scouting methods, his team of scouters influenced enough.

Grizzlies choose him later in the 48th position. Man Boobs was Marc Gasol.

Morey banned the motes in the selections of players and the following year relied on his model.

Collected from the book “The Undoing Project”, by Michael Lewis.

El plan revolucionario

Este libro de nutrición rompe con muchos dogmas adquiridos por la sociedad occidental de nuestros tiempos. Habla sobre como mirar la alimentación como una parte más de nuestra vida, recordarnos de donde venimos y como el marketing nos ha cambiado los hábitos, revisar cada cosa buena y mala que una acción tiene sobre tu cuerpo, volver a los conceptos básicos…

No sé si el autor es consciente de conceptos de medicina china, pero hay mucho de ello en el libro. Habla de energía, de las relaciones del cerebro, las hormonas y el estómago, de estrés, de ejercicio…

El libro va de lo teórico a lo práctico, estando esto último muy bien ajustado a la vida media de un español medio. La aportación de un plan básico y otro más detallado creo que es muy acertada. Las reglas nemotécnicas que ofrece son muy acertadas y de tanto repetirlas en el libro no se te olvidan.

Coincido con la mayoría de los principios que aconseja, pero hay algunos hábitos, como la ingesta tan alta de carne con la que no estoy deacuerdo.

Comer es algo que hacemos de por vida, aprender de nutrición es siempre algo que nunca está de más. A todo el que me ha preguntado si lo recomiendo leer, le he dicho que ojee el blog, que lea sobre los aspectos básicos allí y que si le gusta que lo compre, que se lea el libro y que descubra todo lo que hay detrás (es más que un libro).

Diario de invierno

Con Javier en casa y el resto del jaleo, es complicado sacar tiempo para leer. Dormir es una necesidad básica de la que me cuesta prescindir. Eso si, en esta semana de diciembre con viajes a Madrid y Barcelona, me dio tiempo a leer este diario lleno de reflexiones y anécdotas.
