TAA Strategy – Volatility Harvest ML Long/Short

This strategy implements a Tactical Asset Allocation (TAA) approach that dynamically adjusts portfolio exposure between equities, gold, and short positions based on market conditions, volatility, and machine learning signals.

? Core Idea

The strategy reacts to market regime changes using:

• Volatility signals (VIX)

• Trend and momentum (SPY)

• Machine learning predictions

• Cross-sectional stock selection

It combines long exposure to strong assets, defensive allocation (gold), and short positions in weak stocks.

? Universe Selection

The algorithm selects stocks in two stages:

1. Coarse filter

   • Price > $5

   • High liquidity (Dollar Volume > $20M)

   • Top ~2000 stocks

2. Fine filter

   • Market cap > $1B

   • IPO older than 1 year

   • Select top ~150 most liquid

Additionally, it keeps a Top 4 largest companies (by market cap) for long allocation.

? Long Allocation (Equity + Gold)

Long exposure is dynamically allocated between:

• Top large-cap stocks

• Gold (GLD) as a defensive asset

Regime logic (based on VIX & SPY):

• ? High fear (VIX high + market drop)
  → Aggressive equity allocation
  → ML can increase exposure further

• ? Low volatility / overbought market
  → Reduce equities
  → Increase gold

• ⚖️ Normal conditions
  → Balanced allocation

• ? Extreme volatility spike
  → Exit equities
  → Move to gold

? Machine Learning Overlay

A Random Forest model is trained monthly using:

• VIX features (z-score, percentile, ratios)

• SPY returns (5d, 10d, 20d)

• Trend indicators (SMA50, SMA200)

• Volatility

Target:

• Predict whether SPY will rise >2% in next 21 days

? If bullish:

• Increase equity allocation

• Overweight strongest large-cap stock

? Short Strategy (Alpha Generation)

The strategy also runs a short-selling component:

• Weekly rebalancing

• Select worst candidates using:

  • Hurst-like trend measure

  • Momentum exhaustion

  • Distance from moving average

Only stocks that are:

• Overextended

• Losing momentum

• High score (weakness signal)

? These are shorted with equal weight.

? Risk Management

Multiple layers of protection:

Long side:

• Trailing stop system (multi-stage):

  • Reduce position at drawdowns

  • Fully exit if trend breaks

Short side:

• ATR-based stop loss

  • Exit if price moves against position

Portfolio level:

• 5% trailing stop risk model

• Margin-aware position sizing

? Portfolio Structure

• Long gross exposure ≈ 90%

• Short gross exposure ≈ 60%

• Dynamic allocation based on regime

Result:

• Market participation in bull phases

• Protection in volatile markets

• Additional alpha from short side

? Summary

This TAA strategy combines:

• ? Macro signals (VIX + SPY)

• ? Machine learning predictions

• ? Trend + momentum logic

• ? Short-selling alpha

• ?️ Advanced risk management
