The strategy continued to do well with Autohome Inc., an online source for automotive information in China that receives most of its revenue through advertising and subscriptions from dealers, Mr. Thomas said. Autohome was up 188.2% for the year ended Dec. 31.
Zevenbergen Capital Investments LLC's Z/Tech strategy, a concentrated growth portfolio that looks for companies that are disrupting industries, ranked second on the one-year list, with a gross return of 52.5%.
Joseph Dennison, associate portfolio manager at Zevenbergen, attributed the success of the strategy to the continuation of its high-conviction, high-growth strategy.
"We focus on rapidly growing companies with strong technological advantages," Mr. Dennison explained. "Those companies were certainly rewarded in 2017 and in the fourth quarter."
He cited Mercadolibre Inc., an Argentina-based e-commerce company, as one of the strategy's top-performing stocks.
"As a dominant player in the infrastructure in Latin America, they saw growth accelerate in 2017 in the region and gained the lion's share of the benefit," Mr. Dennison said of Mercadolibre.
Z/Tech also ranked first on the five-year list, unchanged from last quarter, with an annualized gross return of 28.57% over the five years ended Dec. 31.
Morgan Stanley Investment Management had two of its large-cap growth strategies make the one-year list this quarter — its Multi-Cap Growth strategy, at No. 3, with a gross return of 49.85%; and its Growth strategy, at No. 7, with a gross return of 44.97%.
"It was a strong year in the market, and the funds did particularly well," said Dennis Lynch, head of growth investing at Morgan Stanley Investment Management. "Our strategy is to make good long-term decisions. And if you're doing that, you'll have pockets of strong outperformance."
Mr. Lynch said "there was a lot of market rotation and stock-specific volatility" after the election, which "hurt the funds for a short period of time."
And Mr. Lynch explained that although the company doesn't typically make tactical changes every year, MSIM took this volatility as an opportunity to get more concentrated in technology stocks, which wound up paying off, with many internet companies up more than 50%.
"We benefited from our positions in those areas and got aggressively positioned in those areas at the end of 2016," Mr. Lynch said. "We thought the risk-rewards were very compelling."
Mr. Lynch attributed the bounce back in these stocks "to good strong fundamental performance from those companies in addition to the strong market tailwind."

He is co-lead portfolio manager of the Technology Equity strategy.
"The growth rate is accelerating. It's attracted investors to both sectors quite a bit. Pricing and growth has been better than expected in the cloud computing sector," Mr. Price said, adding that the company "rotated a little bit from semiconductors and more into cloud computing, so we got that transition right."
