Algorithmic ETF strategies,
run in your own Alpaca account.
Our strategies use 2x–3x leveraged and volatility ETFs, rebalance daily, and carry a backtested beta of about 1.2 to the S&P 500. They can lose most of their value in a sharp decline.
Our investment philosophy
Philosophy
We believe markets are inefficient in the short term, creating predictable patterns that can be systematically exploited through disciplined quantitative methods.
- Remove emotional decision-making from investment process
- Focus on risk-adjusted returns over pure performance
- Accept leveraged, directional risk: the strategies can lose most of their value in a sharp decline
- Expect results to move with the market: backtested beta is about 1.2 to the S&P 500
Process
Our strategies are built on rigorous backtesting, continuous monitoring, and adaptive algorithms that respond to changing market conditions.
- Backtesting over each strategy's available price history
- Once-daily evaluation and rebalancing near the market close
- Multi-timeframe analysis and signal confirmation
- Continuous strategy refinement and optimization
