AlphaGBM Duan Yongping Analysis

Instant Duan-style framing for a single ticker. Three scoped outputs:

1. Sell Put — if you're "willing to buy at $X", what does selling a Put at $X actually pay, and how does the cost basis work out if assigned?
2. Covered Call — if you hold 100 shares, what yield can you pick up by selling a ~5% OTM Call 25-50 DTE? If called away, what's the total return?
3. Panic Buy Context — what's VIX telling us right now? Are we at Duan's "extreme fear = extreme opportunity" tier (VIX ≥ 35), or is this a wait?

Each panel is tailored to the Duan framework: seller-only, rent-collection, holding quality companies indefinitely, and treating extreme VIX spikes as opportunity rather than threat.

Why This Is a Separate Skill

The generic alphagbm-options-strategy can compute any spread. But Duan Yongping's style has three very specific moves and a very specific philosophy. This skill packages that philosophy into a single call with Chinese-native copy that fits how Chinese retail investors actually talk about these trades.

How to Use

Input:

• ticker (required)
• buy_price (optional) — your "I'd happily buy at this price" level; defaults to spot × 0.95 if omitted

Output (each panel may be null if no suitable contract exists):

• sell_put: {strike, premium, annualized_yield_pct, if_assigned_cost_basis, delta, dte}
• covered_call: {strike, premium, annualized_yield_pct, upside_cap_pct, total_return_if_called_pct, dte}
• panic_buy: {vix, level, signal (bool), action_zh, action_en}
  • level ∈ normal / caution / extreme_fear
  • signal = true when VIX ≥ 35 (Duan-buy tier)

Plus meta: ticker, stock_price, expiry_date, dte, timestamp.
