Neither. Just a market fluctuation.

re Fluctuation:

Can trader algorithms sense a down turn and sell and then sense the bottom and buy back?

I spent much of my career about 40 feet down the hall from my firm's trading floor. This "fluctuation" looks like an emotional reaction to me (i.e. it's not based on any apparent fundamentals...just a reaction to the uncertainly created by Trump's negotiating style).
