Audio and video products maker Poly POLY.N soared 48.6% after HP Inc HPQ.N announced it would buy the company for $1.7 billion in cash. Apple Inc AAPL.O fell 1.6% after a report that the company was planning to cut iPhone and AirPod output as rising inflation starts to weigh on demand for consumer electronics. "Those two factors got priced into the market and there was some level of certainty produced, particularly by the Fed meeting, that resulted in a pretty significant rally," said Jay Hatfield, chief investment officer at Infrastructure Capital Management in New York.
