Today’s biggest winners and losers in the stock market, a look at the notable movers: 

On this episode of Stock Movers: 
A deepening sell-off in chip and memory stocks dragged all four major U.S. equity indexes lower by midday Tuesday. Samsung Electronics set the tone for the broader market overnight. The South Korean memory-chip maker forecast a huge surge in profit, but that wasn’t enough to stop investors from ditching shares. Micron Technology (MU) dropped 5.4%. Intel dropped (INTC) 9.2% and Advanced Micro Devices (AMD) was down 5.6%. 
Shares of Rivian Automotive (RIVN) tumble more than 15% after the electric vehicle firm said it will sell 75 million shares to fund equity contributions related to a US Department of Energy loan. The offering would raise about $1.5 billion at the closing price of $20.14 per share, with Goldman Sachs Group Inc. leading the share sale. Rivian intends to use the proceeds for purposes including making contributions under the amended loan agreement with the Department of Energy. 
Fiserv (FISV) shares rise as much as 6.9% after the Wall Street Journal reported that big Wall Street banks have held preliminary discussions about a deal to acquire a debit network owned by the financial-technology company. JPMorgan Chase, Bank of America, Wells Fargo and PNC Financial Services Group were the banks involved in the discussions, according to the WSJ.
