WSTBX Investment Objective and Strategy
Nomura Science and Technology Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Ivy Funds.
Investment objective
To seek to provide growth of capital.
Principal investment strategy
Ivy Science and Technology Fund invests primarily in the equity securities of science and technology companies around the globe. Under normal circumstances, the Fund invests at least 80% of its net assets in securities of science or technology companies. Such companies may include companies that, in the opinion of IICO, derive a competitive advantage by the application of scientific or technological developments or discoveries to grow their business or increase their competitive advantage. Science and technology companies are companies whose products, processes or services, in the opinion of IICO, are being, or are expected to be, significantly benefited by the use or commercial application of scientific or technological developments or discoveries. The Fund also may invest in companies that utilize science and/or technology as an agent of change to significantly enhance their business opportunities.
The Fund may invest in securities issued by companies of any size, and may invest without limitation in foreign securities, including securities of issuers within emerging markets. The Fund is non-diversified, meaning that it may invest a significant portion of its total assets in a limited number of issuers. IICO typically emphasizes growth potential in selecting stocks; that is, IICO seeks companies in which earnings are likely to grow faster than the economy. IICO aims to identify strong secular trends within industries and then applies a largely bottom-up (researching individual issuers) stock selection process by considering a number of factors in selecting securities for the Funds portfolio. These may include but are not limited to a companys growth potential, earnings potential, quality of management, valuation, financial statements, industry position/market size potential and applicable economic and market conditions, as well as whether a companys products and services have high barriers to entry.
The Fund typically holds a limited number of stocks (generally 40 to 60). Many of the companies in which the Fund may invest have diverse operations, with products or services in foreign markets. Therefore, the Fund may have indirect exposure to various foreign markets through investments in these companies, even if the Fund is not invested directly in such markets. Generally, in determining whether to sell a security, IICO uses the same type of analysis that it uses in buying securities in order to determine whether the security has ceased to offer significant growth potential, has become overvalued and/or whether the company prospects of the issuer have deteriorated due to a change in management, change in strategy and/or a change in its financial characteristics. IICO also may sell a security to reduce the Funds holding in that security, to take advantage of what it believes are more attractive investment opportunities or to raise cash.
