Prediction: Flat to down (no chart).
Confidence: Medium
On Friday I noticed Yahoo Finance provided 2 different stock charts for the same URL for the same day, possibly by browser. The Y axis of the chart served to my Google Chrome showed a higher range of numbers, which compressed the vertical change, yielding a chart that appeared flat:
The chart served to my Safari browser had a Y axis with a smaller range, yielding a more exaggerated chart:
This highlights a problem with trying to predict how a chart will appear visually, since I may see two wildly different charts to represent the same data. Today I will only view the chart served to Safari. I predict will a chart that will be very similar, containing ups and downs, but ultimately ending near the same place it started, not up, perhaps down slightly.
The past 2 weeks I have had walking pneumonia.  Between that and the cold medicine I’ve been taking, I wonder if these matters negatively impact my results. If I get a negative result today, I may postpone further predictions until I’m feeling better.
