The HTML file below deals with the perception of trading decisions within the context of building a long-term stock portfolio. It is the continuation of a series of articles dealing with the underlying math behind a stock trading strategy.
Instead of looking for a trading strategy that tries to shift its portfolio weighs from period to period as in a Markowitz or Sharpe rebalancing scenario, the search is for long-term repeatable procedures that can affect a portfolio's payoff matrix over its entire multi-period multi-asset trading interval. The main interest is not in a trade here and there but on the possible thousands and thousands of trades over a portfolio's lifespan. All influenced by the trading functions put on the table.
The HTML file below highlights the output of a trading strategy, and what should be done to improve upon it. It can be resumed in two charts:
#1 Average Win Distribution

#2 Average Loss Distribution

A trading strategy should have for objective to shift to the right the average profit per trade. Doing so will improve overall performance.
These articles are a lot more for my benefit than anything else. They serve as preparation for my game plan, to gain a better understanding of what I need to do. I don't want to just convert some of my existing trading strategies from one language to another. I want to do more, produce better overall programs and trading strategies. To go beyond what I have done before. Hope it can help others design their own better strategies based on these observations.
This document is being offered in HTML due to the many formulas.
