Alphagbm Hedge Advisor

Scenario-driven hedge recommendations for an existing stock position. Takes ticker + cost basis + purpose, auto-classifies the holding situation (falling knife / bottom-fishing / gain-protection / normal) and returns concrete Long Put, Collar, or Tier-down recommendations with live strikes and premiums from the current option chain. Triggers: "hedge my AAPL", "protect my NVDA gains", "collar strategy MSFT", "long put for TSLA", "how to hedge falling knife COIN", "reduce risk BABA", "lock in gains META", "downside protection", "portfolio hedge", "insurance for position"

"I own AAPL at $140 and it's now $180 — how do I protect the gains?"

Takes that question literally. Given a ticker + cost basis + position purpose, the skill classifies the holding into one of four scenarios and returns ready-to-trade hedge specs with strikes and costs already resolved from the live option chain.

Scenarios

Scenario	Trigger	Recommended Hedge
Falling Knife	Recent drawdown ≥ 15% from 30-day high AND PnL ≤ +5%	Long Put 5% OTM, 75 DTE, 100% cover, budget ~5%
Bottom Fishing	PnL within ±8% of cost AND purpose = just_bought or long_term	Long Put 5% OTM, 90 DTE, 50-75% cover, budget ~3%
Gain Protection	PnL ≥ 15%	Collar 95/110 (zero-cost or net-credit) + Tier-down as alternative
Normal Hold	Fallback when no scenario fires	Position rules only, no urgent hedge

What's Returned

For each recommendation spec, the skill resolves actual strikes and prices from the live option chain:

• Long Put: strike, DTE, cost_per_share, cost_per_contract, cost_pct_of_spot, delta, IV
• Collar: long_put_strike, short_call_strike, put_cost, call_credit, net_cost_per_share (negative = you receive a credit), breakeven analysis
• Tier-down / Position rules: static rules copy only

Also returns a position_rules[] array (single-name ≤20%, sector ≤30-35%, cash reserve 10-15%, etc.) for the normal-hold case.

How to Use

Input:

• ticker (required)
• cost_basis (required, float — your average entry price)
• purpose (optional, default long_term) — one of long_term / short_term / pre_earnings / just_bought

Output:

• Scenario label + reason (zh/en)
• Current price, cost basis, unrealized P&L %, recent drawdown %
• recommendations[] — each with type, priority, title, rationale, and resolved block containing the actual priced hedge
• position_rules[] — always-applicable sizing rules

Example Queries:

• hedge my AAPL at $140, now it's $180 → Gain Protection → Collar 95/110 quote
• I just bought NVDA at $110 on the dip, should I hedge? → Falling Knife or Bottom Fishing → Long Put 5% OTM 60-90 DTE
• how to protect my TSLA position → Gain Protection or Bottom Fishing based on PnL
• collar MSFT at cost 340 current 410 → Full collar pricing
