In case you missed my segment tonight on CNN, here are 5 things you should know about market conditions before Wall Street opens back up:

1. The Dow and S&P 500 had their worst week since 2008 last week, but are basically at the same levels as one year ago.

2. Most data fundamentals and corporate numbers are strong, but fear about the Eurozone crisis is the likely X factor bringing down markets. 

3. IMF and World Bank leaders warn that this solvency crisis in Europe could make the 2008 liquidity crisis look like a piece of cake.

4. Gas under $3 could be a short-term good stimulus for US consumer spending. 

5. Gas under $3 could also mean slowing energy demand which is a negative to long-term US consumer confidence and spending.
