About SPX Weekly Put Spread
SPX Weekly Put Spread collects option premium on the S&P 500 index. Each Monday it sells a put spread around 10 delta with the following Friday’s expiry, buys protection 50 points lower, and closes early at 50% of the credit or when a volatility-based stop is hit. SPX options are cash-settled and European-style.
How it works
Black-box strategy. Harbour Quant has chosen to keep the trading logic confidential. Lantern has verified the backtest and tracks every live signal, so the performance, risk metrics and trade history above are independently checked even though the rules are not disclosed.
Risk notes
Premium selling wins often and loses rarely but in larger amounts, especially on sudden sell-offs. The bought put caps each week’s loss. Returns in rupees also move with the dollar.
Combine with other algos
Correlation of monthly returns between SPX Weekly Put Spread and other algos. Low or negative correlation means they tend not to draw down at the same time, which steadies a portfolio.
