(Reuters) - Global equity funds led investment inflows in the week to Feb. 17, as fund investors favoured riskier assets on optimism over the coronavirus vaccine roll-outs and expectations of a massive U.S. stimulus package. Investors purchased $26.5 billion in equity funds last week, marking a tenth straight month of net buying in equity funds, Refinitiv Lipper data showed.

Investors poured some $5.7 billion into funds that invest in U.S. short-term and medium-term bonds, or bonds maturing between 1-5 years, the data showed. Funds investing in inflation-linked bonds, which are structured to provide protection against rising inflation, lured about $1.1 billion.

Funds investing in the technology and healthcare sectors led equity inflows. Investors poured $6.98 billion into tech funds, followed by $1.12 billion into healthcare funds during the week, data for 1,170 tech funds and 861 healthcare funds, based on Lipper’s sector classification, showed.
