Unpredictability spooks markets: The VIX—Wall Street's go to measure of future volatility—jumped 12% on Monday, the largest one-day increase since early November. Low volatility was one of the more dubious features of the 2017 stock market. The Trump administration may have business-friendly intentions, but yesterday's declines show the downside of unpredictability.

Aetna report earnings before the bell this morning: The health insurer's outlook may provide a hint of the sector's strategy going forward as the Trump administration pulls efforts to sign up Obamacare enrollees.

Signs of rising inflation? Released at 8:30, the Employment Cost Index is the most comprehensive gauge of rising compensation available. If we see a big spike in the Q4 2016 reading, the market will take that as evidence that the Fed will raise rates more aggressively this year.

The incoming administration is planning extraordinary steps to protect its most prized commodity, Joe Biden, including requiring daily employee COVID tests and N95 masks at all times, according to new guidance sent to some incoming employees Tuesday.

Why it matters: The president-elect is 78 years old and therefore a high risk for the virus and its worst effects, despite having received the vaccine. While President Trump's team was nonchalant about COVID protocols — leading to several super-spreader episodes — the new rules will apply to all White House aides in "high proximity to principals."

The Department of Justice told Sen. Richard Burr (R-N.C.) on Tuesday that it will not move forward with insider trading charges against him.

Why it matters: The decision, first reported by the New York Times, effectively ends the DOJ's investigation into the senator's stock sell-off that occurred after multiple lawmakers were briefed about the coronavirus' potential economic toll. Burr subsequently stepped down as chair of the Senate Intelligence Committee.
