News that Goldman Sachs Group Inc. was part of a $500 million investment in social networking site Facebook helped lift the stocks Monday of other big companies that recently put money into hot technologies.
Goldman shares rose $4.65, or 2.8 percent, to $172.81 in afternoon trading.
The New York investment bank and a Russian investor together took a stake in the ubiquitous social site, according to a report by The New York Times over the weekend. The stake implies that the Palo Alto, Calif.-company is worth about $50 billion.
Also gaining in Monday's session were shares of Morgan Stanley and T. Rowe Price.
The two publicly traded companies were among a group of large investors, also including Fidelity Investments, who put $500 million in Groupon, the 2-year-old social buying site that sends daily localized coupons for restaurants and attractions to more than 50 million subscribers worldwide, the Times reported Thursday.
Morgan Stanley shares added $1.21, or 4.5 percent, to $28.42.
T. Rowe Price stock hit a 52-week high of $66.15 during the session, and remained up $1.57, or 2.4 percent, at 466.11 in afternoon trading.
Also hitting an intraday high was Amazon.com Inc., which topped out at $186 per share. The stock remained up $5.61, or 3.1 percent, at $185.51 in afternoon trading. The online shopping site last month invested $175 million in Groupon competitor LivingSocial.
