Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The consumer discretionary sector was driven by inflation expectations during the reporting period, beginning with persistent inflation, rapid rate hikes, and the potential for a U.S. recession then rallying on dovish remarks from the U.S. Federal Reserve Bank at the end of 2023.
However, the performance of consumer discretionary stocks lagged that of the broader market as inflation proved to be stickier than expected, and consumer confidence failed to recover in line with investor confidence.
Investors’ persistent enthusiasm for artificial intelligence (“AI”) was the primary driver of market returns. While the enthusiasm may have contributed to broad stock price increases, the largest increases were reserved for big technology companies that were best positioned to harness the new technology, leaving less exposed and smaller-capitalized companies to underperform.

What contributed to performance?

Within consumer discretionary stocks, a preference for experiences over goods led select fast-casual food chains to deliver strong performance. The influence of generative AI helped companies with a greater claim to benefit from the technology regardless of their main business. A large technology company with services ranging from e-commerce to cloud computing particularly gained due to its position as a leader in the AI space.

What detracted from performance?

An athletic gear company was the largest detractor from the Fund’s return during the reporting period. The company’s stock price has been challenged as investors preferred to spend their discretionary dollars on experiences over physical goods. Following similar trends, a budget retailer was the second largest detractor.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

Generative artificial intelligence (“AI”) was a significant driver of market returns during the reporting period, particularly among firms providing the hardware or software that empowers AI delivery and utilization. These firms have been led by large technology companies, Mega-cap companies accounted for a vast majority of the sector’s gains relative to mid- and smaller-capitalized companies.
Technology firms continued to receive fiscal support from legislation passed in 2022, empowering the United States to capitalize on the emergence of new technologies and deliver self-sufficiency in innovation and production.
The U.S. Federal Reserve Bank (“Fed”) kept interest rates steady throughout the reporting period. A global risk-on rally started when Chairman Powell signaled rates had peaked at the end of 2023, fueling hopes for a soft landing (an economic outcome in which inflation slows to the Fed’s 2% target while growth remains positive).

What contributed to performance?

The two largest individual contributors to the Fund’s return during the reporting period were U.S. companies offering semiconductor and infrastructure software solutions. Both companies benefited from the ongoing AI trend as developers of the chips and software used in emerging technology development.

What detracted from performance?

Two of the largest individual detractors from the Fund’s return during the reporting period were data storage and management solution providers. Like their peers supplying the tools to harness AI, their stocks traded at high multiples, but weakened earnings guidance provided by the firms during the period caused stock prices to fall.
