negative and positive skew tendency

One of the most interesting things that I read on Systematic trading by Robert Carver is the tendency that a trader can have when doing his transactions.

The concept

Basically when you are completing a long-short action (completed transaction), ideally you will have positive outcomes and negative outcomes. If you accumulate all these results and you order it, you will have a Gaussian bell. This bell will not be perfect, it will have different shapes.

The trader with negative skew, will have:

  • high number of transactions are completed positively, with small amounts of profit.
  • Few amount of transactions are completed in a negative way, but with high loses.

The trader with positive skew, will have the opposite situation.

It’s important to understand the way you make decisions, the results they return and identify the pattern of behavior you have.

Once done, you can identify the weaknesses of your behavior and then include some habits on your trades to be able to improve your trading in a systematic way.

I generally act as negative skew trader

For a negative skewed trader, there are ways to minimize the negative skew. The main ones are:

  • Use stop loss to cut the loses.
  • Use stop loss to not directly sell a stock but protect the minimum margin while you let it grow and grow.
  • Divide the longs in 2 moves, to decrease the average cost.

Other times I act as positive skew trader

And these times is when I use to manage better the capital that is involved in the trade.




Chowder rule

I have just realized about this guy named Chowder. He has a guidance method to guide your investments and create habits that enable you to increase the value of your equity.

It starts with basic rules and they increase their complexity with respect you go in deep.

Portfolio diversification

Use the Morning Star classification based on economic sensitivity and divide the equity as follows:

  • Defensive = 50%
  • Cyclical = 25%
  • Sensitive = 25%

High Total return

Chowder defines the concept of “high total return” that is calculated as follows:

High Quality Stock + High Current Yield + High Growth of Yield = High Total Return.

This total return you take the current yield, the minimum value of 3 years, 5 years or 10 years dividend growth and ideally the total return should be at least over 10%

Current Yield + Min(3 / 5 / 10) Year Dividend Growth = Total Return.

The 10% threshold is an initial threshold that can be increased depending on the market situation.

Systematic trading by Robert Carver

I was looking for a trading book that goes beyond to the typical basic concepts and that send messages as “this is the book that will make you millionaire”.

Well, this is the first book I found with this characteristics. Very complete one, and complex enough that is going to force me to review many concepts again in detail.

Any other suggestion for next book?

Squeeze Momentum Indicator by LazyBear

Squeeze Momentum Indicator by LazyBear is a volatility indicator that I discovered in TradingView.

This is a derivative of John Carter’s “TTM Squeeze” volatility indicator, as discussed in his book “Mastering the Trade” (chapter 11).

Black crosses on the midline show that the market just entered a squeeze ( Bollinger Bands are with in Keltner Channel). This signifies low volatility , market preparing itself for an explosive move (up or down). Gray crosses signify “Squeeze release”.

Mr.Carter suggests waiting till the first gray after a black cross, and taking a position in the direction of the momentum (for ex., if momentum value is above zero, go long). Exit the position when the momentum changes (increase or decrease — signified by a color change). My (limited) experience with this shows, an additional indicator like ADX / WaveTrend, is needed to not miss good entry points. Also, Mr.Carter uses simple momentum indicator , while I have used a different method (linreg based) to plot the histogram.

Anticancer, a new way of life

I had this book in my list since a couple of years or so, finally I read it once a sibling was affected by the disease.

It’s a very valuable book independently of the circumstances. I was happy to discover that I was doing so many positive things to prepare the ground to avoid the disease.

The physiologic part of the book is very valuable, and put me on the perspective about what was happening to my family during these moments.
