Sept 25 (Reuters) - Wall Street's main indexes rose on Friday, led by technology-related stocks, but were still set for their longest weekly losing streak in a year as fears about the coronavirus' impact on the economy weighed on investor sentiment.
Shares of tech mega-caps including Facebook Inc, Alphabet Inc, Amazon.com Inc, Apple Inc and Netflix Inc, which are perceived as relatively safe assets at a time of economic uncertainty, climbed between 0.4% and 1.9%.
The information technology index jumped another 1.2% after outperforming for most of the week as investors ditched value-linked stocks in the face of deteriorating economic data.
