Reader ‘G’ and I have exchanged notes today on some incorrect price quotes on a list.
After double checking it appears that Google had a bad price or two on Tsakos Energy Navigation preferreds. Of course with a bad price for today it makes the ‘change’ column incorrect–a compounding of issues so to speak. The volumes on the issues were correct.
In this case the prices are incorrect by about 20 cents–so not terrible–and many times we find prices differ from exchange to exchange by 2-3 cents.
We have double checked our formulas etc and they are correct. We have used Google quotes for years and find them generally correct–but they do go off the rails on occasion.
So as we have said before we believe the data in all the lists should be around 98% correct-but the lists are just a starting point for you and your brokerage quotes are the gospel for your trades.
