Here the four questions that Tim Reazor discussed at our Dec 14, 2011 meetup:

Four questions to ask yourself when you are considering selling.

1 - Did my stock slice below the 10 week sma / 40 week sma or 50 sma day 200 day sma?

2 - When my stock is coming down in price is it gapping down?

3 - When my stock is coming down in price is it coming down in high volume.

4 - Has the market's trend changed?
