longbridge-hedging

Design and evaluate hedging strategies for a portfolio or single position using Longbridge market data — from simple Beta hedges to options-based protection and cross-asset tail-risk hedges.

Workflow

Step 1 — Identify hedge objective

Clarify with the user:

What is being hedged: single position, portfolio, or sector exposure?
Risk to hedge: market Beta, tail event, currency, or volatility?
Hedge horizon: days, weeks, or months?
Cost tolerance: zero-cost (collar) or willing to pay premium?

Step 2 — Fetch data

bash

longbridge kline --help
longbridge option --help

# Beta calculation (60-day daily returns)
longbridge kline <SYMBOL> --period day --count 60 --format json

# Option chain for hedge instruments
longbridge option chain <SYMBOL> --format json

# Current portfolio positions (requires login with trade scope)
longbridge positions --format json

Step 3 — Beta hedge

Portfolio Beta:

β_portfolio = Σ(w_i × β_i)

Compute individual Beta for each holding from 60-day returns vs benchmark (SPX / HSI / CSI300). Fetch benchmark kline with

longbridge kline <BENCHMARK> --period day --count 60 --format json

.

Hedge ratio (index futures or inverse ETF):

Contracts needed = (Portfolio Value × β_portfolio) / (Futures Price × Contract Multiplier)

Present: number of contracts, hedge cost, and residual Beta after hedge.

Step 4 — Options-based protection

Protective Put:

Buy ATM or slightly OTM put on the underlying or index.
Cost = put premium; protection kicks in below strike.
Effective floor = Strike − Premium paid.

Fetch available strikes:

longbridge option chain <SYMBOL> --format json

.

Collar Strategy (zero-cost or near-zero):

Buy OTM put (downside protection) + sell OTM call (cap upside).
Net premium ≈ 0 if call premium offsets put premium.
Present: put strike, call strike, net cost, max gain, max loss.

Selection criteria:

Criterion	Protective Put	Collar
Upside retention	Full	Capped at call strike
Cost	Premium paid	Near zero
Best for	Bullish with hedge need	Neutral/mild bearish

Step 5 — Tail risk hedges

Tool	Instrument	Mechanism
VIX calls	UVXY.US / VIX options	Profit from volatility spike
Gold	GLD.US / 518880.SH	Safe-haven in risk-off
Long-dated US Treasuries	TLT.US	Negative correlation with equities
Put on index	SPY puts / HSI puts	Direct market hedge

Note: fetch current price and recent kline for any hedge instrument before recommending.

Step 6 — Currency hedge

For HK/US cross-currency portfolios:

USD/HKD is pegged — minimal FX risk.
CNY exposure: use offshore RMB (CNH) forwards or futures.
Non-HKD Asian exposure: fetch FX rate via
```
longbridge fx --format json
```
(verify flag with
```
--help
```
).

Present notional hedge amount, instrument, tenor, and estimated cost.

Step 7 — Hedge cost assessment

Cost efficiency = Protection value / Premium paid

Present: premium as % of protected notional, breakeven move, and expected cost per 1% of downside protection.

CLI

bash

longbridge kline --help
longbridge option --help
longbridge positions --help

longbridge kline <SYMBOL> --period day --count 60 --format json
longbridge option chain <SYMBOL> --format json
longbridge positions --format json

Output

Present:

Hedge objective summary.
Recommended strategy with rationale.
Implementation details (strikes, contracts, premium).
Cost vs protection table.
Scenarios: portfolio value if market falls 10% / 20% with and without hedge.
Caveats (basis risk, early exercise for American options, liquidity).

Always note: hedging reduces risk but also limits upside. This is not financial advice.
