[BRIEFING.COM] The S&P 500 trades just above its 200-day moving average (5,730). The index reached 5,731 at its low.
Marvell Technology (MRVL 73.56, -16.61, -18.4%) and MongoDB (MDB 203.30, -60.91, -23.0%) are notable laggards today after neither managed to meet investors' high expectations with their guidance after reporting their quarterly results.
The weakness in MRVL has contributed to weakness in chipmakers, leading the PHLX Semiconductor Index to trade 4.0% lower.
