An FYI,
I got the following warning from my broker today about trading Amazon options that expire on Apr 29th. On expiration day, be aware that expiring out of the money options may have a lot of premium, at the close of trading, due to earnings after the close. There is also a risk of assignment on short out of the money options due to after hours moves.
*We’d like to alert you to a potentially high-risk situation regarding a new expiration listing in* ***AMZN****. A new expiration date of April 29 has been listed, and AMZN also has expected earnings on this date. Generally, the Options Exchanges and OCC intend to avoid this situation because of the risk of increased volatility and after hours moves.*
*We encourage you to consider limiting the exposure of your accounts, especially on short contracts*
