Position Sizing Based on Seasonal Pattern Strength

Position Sizing Based on Seasonal Pattern Strength

How pattern strength metrics can inform allocation decisions.

The Framework

PCS Score Win Rate Pattern Strength
70+ 80%+ Very strong historical pattern
60-70 70-80% Strong historical pattern
50-60 60-70% Moderate historical pattern
Below 50 Below 60% Weak historical pattern

Past performance does not guarantee future results.

Kelly Criterion - A Statistical Concept

Theoretical optimal allocation = Win Rate - (Loss Rate / Reward:Risk)

Example:

  • Win rate: 75%
  • Average win: +4%
  • Average loss: -3%
  • Kelly: 0.75 - (0.25 / 1.33) = 56% of capital

Many practitioners use half-Kelly as a more conservative approach: 28% allocation

Scaling Approach

Some market participants spread entries over time:

  1. Day 1: 50% of planned position
  2. Day 3-5: 30% if direction aligns
  3. Day 7-10: Final 20% on any pullback

Portfolio-Level Considerations

Total Seasonal Positions Common Allocation Range
1-2 positions 30-40% each
3-5 positions 15-25% each
6-10 positions 8-12% each
10+ positions 5-8% each

Key Principle

Risk management is about understanding that even the strongest historical patterns can and do fail in individual years.

This is statistical analysis of historical data, not investment advice. Always do your own research.
