In the case of Red Lion Hotels, I notice it's up 11% and the conference call hasn't even taken place.
Last week, Square (ticker SQ) went up first, then way down, and then slowly back up - there was a lot of volatility - incredible volatility before and after, but perhaps it took a long time to digest the news which was complicated.
One of my brokers has a tool that I am starting to use that I can enter up to 25 ticker symbols all on the same chart. And I can create multiple charts. So I think this feature will help me.
I'll see how it goes on Monday - I'll create the charts now. It should work.
What I'm not always sure is why the charts sometimes don't start showing information in the pre-market, and sometimes do. I guess if there are no transactions on bid/ask, the chart doesn't initialize itself yet. I might need to ask about why the chart is days in the past sometimes early in the morning. It can take all the way until 9:30AM for the chart to start updating - this is a huge problem.
