The 80/20 in Trading
If you review your past 100 trades, you will almost certainly find that a small minority of trades produced the vast majority of your profits. Maybe 15 trades generated 85% of your total gains. The other 85 trades, collectively, contributed very little or even lost money net. This is the Pareto principle in action.
Identifying the Vital Few
The analytical question is: what do the top 20% of trades have in common? Look at the setup type, the market conditions at the time, the timeframe, the asset class, the day of week, your confidence level at entry, and the time you spent analyzing the trade. Often, patterns emerge. Maybe your best trades all came from one specific entry system. Maybe they all occurred during trending market regimes. Maybe they were all in a single asset class.
What to Do With the Insight
Once you identify the characteristics of your best trades, the implication is clear: do more of what works. If your momentum breakout trades in crypto produce 80% of your returns while your mean-reversion trades in prediction markets break even, the optimal allocation of your analytical time and capital is obvious. Focus on the setups where your edge is concentrated.
The harder part is stopping the activities that do not generate returns. The 80% of trades that produce 20% (or 0%) of returns are not just unproductive. They consume time, attention, and capital that could be allocated to the productive 20%. Cutting the unproductive trades is as important as expanding the productive ones.
The Continuous Review
The 80/20 distribution is not static. As markets evolve and your skills develop, the trades that fall in your top 20% may change. Quarterly review of your Pareto distribution keeps your focus calibrated to your current strengths rather than your historical ones.
