Every December MU strangle and straddle, year to date
Recorded in cvforge on June 30, 2026 by ConvexValue · Published July 25, 2026
Not one structure but all of them: the year-to-date performance of every December-expiration strangle and straddle on MU, so the whole strike surface is comparable.
Exact prompt
I want to visualize the performance of all december expiration strangles and straddles on $MU since the start of the year
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
Going from one structure to all of them changes the question. A single strangle’s P&L is an anecdote; the whole set shows which strike distances paid for themselves and which did not, across the same period and the same underlying move.
Read it as a surface rather than a ranking. The best-performing combination is partly luck of where the stock ended up, and picking the historical winner is the classic overfit. The useful signal is the pattern — whether wider or tighter structures did better, and how sharply it falls off.
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.
