Not investment advice

Everything on halfonadouble.com, including the chart, the published price levels, the blog posts and any commentary, is provided for informational and educational purposes only. It is not investment, financial, legal or tax advice, and it is not a recommendation or solicitation to buy, sell or hold any security, option or other instrument. Half on a Double is not registered as an investment adviser, broker or dealer in the United States or any other jurisdiction.

Options are risky

Options trading involves substantial risk and is not suitable for every investor. You can lose the entire amount you commit to a position, and some strategies can lose more than that. Before trading options, read the Characteristics and Risks of Standardized Options published by the Options Clearing Corporation, and consult a licensed professional who knows your circumstances.

Positions

You should assume that the person who runs this site may hold positions in any security or option discussed on it, and may open, close or change those positions at any time without notice.

Accuracy of the data

The levels published here are derived from third-party end-of-day options data using a simplified model. They are calculated after the close, from the previous session’s open interest, and can be stale by the time you read them. The model assumes European-style exercise, a fixed risk-free rate and no dividends, none of which is exactly true. Data vendors make mistakes, software has bugs, and thinly traded contracts have no real price discovery. Nothing on this site is warranted to be accurate, complete or current, and it is presented “as is”.

No liability

To the fullest extent permitted by law, Half on a Double and anyone associated with it will not be liable for any loss or damage, direct or indirect, arising from the use of, or reliance on, anything published on this site.

Historical blog posts

Posts in the blog archive from 2023 and 2024 describe specific trades and entry prices that were relevant on the day they were written. They are kept as a historical record only. Nothing in them is a current recommendation.
