Our Investment Philosophy
Data first. Discipline always.
Since 2014, SixEight SAS has been dedicated to performance-driven investing, combining rigorous analysis, technology, and simplicity to help investors outperform over time.
We spent years testing thousands of market indicators to identify those that truly work, and eliminating those that don’t.
This process gave birth to our proprietary ETF models, optimized to make portfolio management both smarter and simpler.
The Two Pillars of Our Strategy
1️⃣ Momentum - What goes up tends to stay up.
The momentum effect, or performance persistence, is one of the most studied and proven market phenomena.
Assets that have performed well recently often continue to outperform in the short and medium term.
Our models analyze global ETFs every month, ranking them by relative strength.
We then reallocate toward the current leaders, the “winners”, while avoiding underperforming areas.
This helps capture returns efficiently while reducing behavioral biases and unnecessary trading.
Long-term performance of the momentum strategy consistently shows higher risk-adjusted returns.
2️⃣ Market Timing - Protect when risks rise.
Markets are inherently volatile.
To reduce drawdowns, we use a trend signal based on the S&P 500 Index, a global benchmark that often leads other markets.
When the signal turns negative, the model shifts from equities to Aggregate Bond ETFs or cash equivalents until conditions improve.
This helps protect capital during major downturns while keeping the strategy active and responsive.
Why We Trade Once a Month
Markets generate constant “noise”, small fluctuations that don’t reflect meaningful trends.
By limiting trades to one monthly reallocation, our models:
✅ Filter out false signals,
✅ Reduce execution costs,
✅ Focus on genuine long-term trends.
This disciplined pace has proven to deliver stronger and more stable performance over time.

consistent outperformance with less volatility.
