Xero Combo Strategy

Single indicators give many false signals. By requiring multiple indicators to agree (confluence), you filter out low-quality signals and only trade when trend, momentum, volatility, and volume all confirm the same direction. This dramatically improves win rate, though you'll have fewer trades.

XRO is a high-beta SaaS stock - it moves more than steady industrials in both directions, driven by global tech sentiment, overnight US tech, currency, and its own results and acquisition news. That volatility creates more trading opportunities (and risk). It is also one of the most liquid ASX tech options names, which matters for an options-based combo strategy.

Minimum 2 signals should align for a half-position trade (moderate confluence). Ideally, 3-4 signals align for a full position (high confluence). If only 1 signal is positive or signals conflict, skip the trade. The combo strategy's edge comes from requiring multiple confirmations.

Conflicting signals mean no trade. For example, trend bullish (+1) but momentum bearish (-1) gives a net score of 0 or low. This indicates uncertainty - the market isn't clearly directional. Wait for signals to align before trading.

High confluence (3-4 signals aligned) occurs roughly 2-4 times per month on average, and can cluster around results and trending tech-sentiment phases. This is intentional - the strategy prioritizes quality over quantity. You'll have fewer trades but a higher win rate on those you take.

In trending markets (ADX > 25), weight trend and momentum higher (1.5x each). In ranging markets (ADX < 20), weight volatility/BB higher. For exceptional readings (RSI at extremes, volume > 2x), apply 1.5x weight to that signal. This adapts the combo to the current market regime.

For moderate confluence (+4 to +6), enter 50% initially and add 50% on confirmation (price moves 0.5 ATR in direction or confluence increases). For high confluence (+7 or higher), you can enter a full position immediately since confidence is high. Scaling reduces risk on uncertain setups.

Check the ASX All Tech (XTX) trend, XRO RS, NASDAQ overnight, and AUD/USD before any trade. If 3-4 filters are favorable, trade full combo signals. If 2 favorable, trade only high confluence. If 0-1 favorable, reduce all positions by 50% or skip. Environment context is crucial for XRO as a globally exposed tech stock.

For high confluence bullish, use ITM calls (delta 0.65-0.75) or tight bull call spreads capturing the measured-move target. ITM options maximize participation in the expected move. Spreads reduce cost while still capturing most of the move. Use monthly options (20+ DTE) for adequate time, and mind ASX single-stock option spreads.

Monitor daily. Score dropping from high to moderate = warning, consider reducing 33%. Two components flipping against position = reduce 50%. Three flipping = exit. Score increasing = can add to position on pullbacks. Active management based on evolving confluence beats fixed rules.

Use walk-forward optimization: train on 60% of data, validate on 20%, test on 20%. Roll the window forward and repeat. Parameters consistent across periods are robust. Significant out-of-sample degradation indicates overfitting. Target Sharpe > 1.0, profit factor > 1.5 consistently across periods, and re-validate around structural breaks like the Melio acquisition and capital raisings.

Use ML as an ensemble layer. If the traditional score and ML agree (both positive or both skeptical), trade with confidence. If they disagree significantly (score +7 but ML 45%), investigate - ML may detect patterns traditional scoring misses. Use the ML output for position-sizing refinement.

Identify the regime using ADX and volatility percentile. Trending (ADX > 25): weight trend/momentum higher. Ranging (ADX < 20): weight BB/volatility higher. High volatility: wider stops, larger targets. Low volatility: tighter stops, consider selling premium. Apply a regime-specific weight matrix to the combo scoring.

Maximum confluence (+10 to +12 weighted): delta 0.8-0.9. High (+7 to +9): delta 0.65-0.75. Moderate (+4 to +6): delta 0.4-0.5. This scales directional exposure to conviction. Achieve target delta through appropriate strike selection (ITM/ATM/OTM) or position sizing.

The XRO combo, as a single-stock high-beta tech strategy, should target 15-20% of the portfolio VaR budget. Calculate the strategy's VaR contribution: allocation x strategy VaR. Ensure total portfolio VaR stays within budget. XRO is correlated with the ASX tech sector - treat all ASX tech strategies as a single allocation bucket for diversification purposes.
