I wish I knew how to help with timing for reentry. We'll gap up on market open for I would think (though I've been wrong on this for two weeks - we oversold yet???)
Some will sell right away on the bounce so that might be the time to get in. A lot of volatility should go away after 1st hour and I think bid/ask will stabilize.
1 - Buy in after first bounce?
2 - Buy after 1st hour?
3 - Wait and see?
I would like to think with positive catalyst on the way with being oversold should have us reverse direction and its a good rentry point. Wait and see might cost more but less risky as well if somehow this knife keeps falling.
The short term game is notoriously hard to play... my tentative plan is:
If we gap up tomorrow and buying pressure is strong, the 317.50s expiring tomorrow should be doing good... sell those and consider DITM LEAPs.
I would rather see a solid bottom form before getting serious about a large buy. I prefer slow predictable moves down followed by a clear bottom, but the market delivers other than what we prefer!
