Six months of P&L on an MU 1000 straddle
Recorded in cvforge on July 8, 2026 by ConvexValue · Published July 25, 2026
How a single MU strike-1000 straddle performed over six months, tracked from end-of-day option history through a period of large moves in the name.
Exact prompt
Show me the PnL for a strike 1000 straddle on $MU for the past 6 months.
Data cadence
Live U.S. option snapshots, refreshed through the session. Open interest is an end-of-previous-day figure and updates once daily.
Plan requirements
Needs the Research data plan, which adds end-of-day historical options aggregates. The rest of the build runs on the free tier.
Fields used
fair_market_value, strike_price, expiration_date, contract_type, break_even_price, implied_volatility, delta
How to read it
A straddle is long volatility, so the path is the interesting part rather than the endpoint. Six months is long enough for the two forces to fight: realised movement adding value, and time decay taking it back every day regardless.
Read where the line turns. A straddle that ends flat may have been far ahead in the middle, which is a statement about when the move arrived rather than whether it did. Daily marks again, so the curve is a valuation path, not a set of achievable exits.
Change it
The prompt is the interface. Ask for a different ticker, a different expiration window, or an extra column in the same sentence style and the agent edits the app in place — you do not start over, and you do not wait for anyone to build it.
Limitations
- Snapshot data, not a transaction tape: the build reads the chain as it stands, so it cannot attribute a trade to a buyer or a seller.
- Open interest updates once a day, so an intraday volume/OI comparison is always this session’s volume against yesterday’s open interest.
- Contract coverage is U.S. listed equities, ETFs and indices. Indices use the I: prefix, for example I:SPX.
- Current per-contract valuation is Massive fair market value (FMV), a proprietary estimate. cvforge does not provide option bids, asks, midpoint, quote sizes, NBBO or last trades, and FMV is not an executable quote.
- Payoffs use Massive fair market value estimates. FMV is not an executable price, so premiums, P&L and break-evens are theoretical.
- Curves before expiration depend on an implied-volatility assumption held constant; in practice volatility moves with price.
