TSX recap: Index basks in Nvidia's 'halo effect'

Canada's main stock index gained almost 100 points Friday, while U.S. markets mostly held on to their gains after soaring the day before.

This was a strong week for earnings, with a focus on chipmaker Nvidia and its "halo effect" on markets, said Tamsin Wilding, principal and portfolio manager for fixed income at Leith Wheeler Investment Counsel Ltd.

Nvidia reported earnings after the bell on Wednesday that prompted a strong rally across markets the next day. Both the S&P 500 and the Dow notched new records. 

Markets mostly held on to those gains Friday as earnings continued to roll in. The S&P 500 and the Dow both edged higher, again to new records, while the Nasdaq took a small step lower.
