US market and fake WH bomb report?

[Dog Daze]

Why did the US stock market react to the fake AP tweet yesterday of a WH bombing? I thought the market these days was primarily computer programs trading with other computer programs. Is one of he inputs to those programs twitter feeds? Did enough individual investors make kneejerk sales to move the market? Did some hedge fund manager make a big move?

Nervous markets. News affects the markets. Especially if it concerns the POTUS. That would cause a lot of uncertainty.as to what happened and what would happen next. That affects security prices. Investors will dump stocks and move to safety like treasuries. Look what happened to the 10-year treasury. Yield crashed and prices spiked.
