One little bit of event risk that could present itself into March opex is the Fed decision.
The Fed meeting date is on Wednesday March 16.
Now there tends to be a lot of noise surrounding the Fed and whether they will raise or not.
But we have a market to show us the implied odds:

Currently we’re seeing the probability of a rate hike around 2%. So odds are we won’t see any movement from the Fed.
Now that doesn’t mean we won’t see people start to get scared. In about a week you’ll start seeing headlines of “will they/won’t they” that will pop up in financial media. It may not be a good reason to sell stocks, but some investors just may need *a* reason to sell stocks.
