Backtested Performance Limitations
All performance results shown on SystemTrader are based on hypothetical backtested data. Backtested results have significant limitations:
- Hypothetical results: No actual money was invested or traded. Results represent what would have happened if the strategy had been followed historically.
- Hindsight bias: Backtests are designed with the benefit of hindsight and may not reflect real-world decision-making conditions.
- No execution costs: Results may not account for all real-world costs including commissions, slippage, bid-ask spreads, and market impact.
- Survivorship bias: The stock universe may not include companies that went bankrupt, were delisted, or otherwise ceased trading.
- Data quality: Historical data may contain errors, adjustments, or gaps that affect results.
- Market conditions change: Strategies that worked historically may not work in the future as market dynamics evolve.
- Overfitting risk: Strategies optimized on historical data may perform poorly on new, unseen data.
Past Performance Does Not Guarantee Future Results
This is perhaps the most important principle in investing. Historical returns, whether from actual trading or backtesting, provide no assurance of future performance. Market conditions, economic factors, and countless other variables make it impossible to predict future returns with certainty. A strategy that generated exceptional returns in the past may generate losses in the future.
Risks of Stock Trading
Trading stocks involves numerous risks, including but not limited to:
- Market risk: Stock prices can decline due to broad market movements regardless of individual company performance.
- Volatility risk: Stock prices can fluctuate significantly in short periods, leading to substantial gains or losses.
- Liquidity risk: Some stocks may be difficult to buy or sell quickly without affecting the price.
- Concentration risk: Holding a small number of stocks increases exposure to company-specific risks.
- Sector risk: Stocks in specific sectors may decline together due to industry-specific factors.
- Company-specific risk: Individual companies may face challenges that cause their stock prices to decline significantly or become worthless.
- Timing risk: Entering or exiting positions at unfavorable times can significantly impact returns.
Strategy-Specific Risks
SystemTrader offers multiple systematic strategies, each with its own risk profile. All momentum-based strategies share common risks, and each strategy has additional specific considerations.
Common Momentum Strategy Risks
- Momentum crashes: Momentum strategies can experience sudden, severe drawdowns when market trends reverse quickly.
- High turnover: Frequent trading increases transaction costs and may result in short-term capital gains taxes.
- Crowding: Popular momentum strategies may become crowded as more investors follow similar signals, reducing effectiveness.
- Regime dependence: Momentum strategies are designed for bull markets with clear directional trends. They can experience significant drawdowns (>30%) during bear markets or prolonged sideways conditions, and may take extended periods to recover.
7-factor momentum scoring system
- Multi-factor model risk: The 7-factor scoring system is based on specific assumptions that may not hold in all market conditions.
- Factor correlation: During market stress, factors that normally diversify may become correlated, amplifying losses.
- Complexity risk: More factors mean more potential points of failure and harder-to-diagnose underperformance.
- Growth stock concentration: The stock universe focuses on high-growth stocks which tend to be more volatile.
- Bull market strategy: Gemini's backtest period (2023–present) coincides with a strong bull market. Historical testing on 2021–2022 bear market data shows negative returns and drawdowns exceeding 20%.
Sector rotation momentum strategy
- Sector concentration: Investing in only 3 sectors at a time creates significant sector-specific risk exposure.
- Dynamic universe risk: The daily price/volume filtering may cause the stock universe to shift rapidly, increasing turnover.
- Small portfolio: Only 6 positions means high concentration and greater impact from individual stock moves.
- Rotation lag: Sector momentum may reverse before the strategy can rotate out, leading to drawdowns.
- Bull market strategy: Mars's backtest period (2023–present) coincides with a strong bull market. Historical testing on 2022 bear market data shows a –39% return with a 41% max drawdown.
Short weak momentum strategy
- Short selling risk: Short positions have theoretically unlimited loss potential if a stock price rises significantly.
- Short squeeze risk: Heavily shorted stocks can experience rapid price increases as shorts cover, amplifying losses.
- Borrow availability: Stocks may become hard to borrow or recall, forcing position closure at unfavorable prices.
- Margin requirements: Short selling requires margin, and margin calls can force liquidation during adverse moves.
Short bearish structure strategy
- Short selling risk: Short positions have theoretically unlimited loss potential if a stock price rises significantly.
- Pattern dependence: Bar-level pattern analysis may not capture fundamental changes that reverse bearish trends.
- High concentration: Only 3 positions means each stock has outsized impact on portfolio performance.
- No regime filter: The strategy is always in the market with no broad market filter, increasing risk during bull markets.
