1. Green Christmas
Joy to the investor! While some market participants worried that the so-called Santa Claus rally wouldn't materialize this year, the major indexes all notched wins in last week's holiday-shortened trading period. The S&P 500 also gave traders the gift of new all-time highs. Here's what to know: The three major indexes climbed more than 1% a piece last week, marking each index's fourth positive week in the last five.
Despite ending Friday's session slightly lower, the benchmark S&P 500 still logged fresh intraday records and got within 1% of the 7,000 milestone.
It's another shortened trading week with the stock market closed Thursday for New Year's Day.
Plus, it's a light week for economic data and corporate earnings. However, investors will keep an eye on minutes from the Federal Reserve's December meeting due out New Year's Eve.
