| Risk [Text Block] | Concentration. The Fund’s strategy of concentrating in technology and related companies means that its performance will be closely tied to the performance of a particular market segment. The Fund’s concentration in these companies may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in these companies would have a larger impact on the Fund than on a mutual fund that does not concentrate in such companies. At times, the performance of these companies will lag the performance of other industries or the broader market as a whole

| Risk [Text Block] | Growth Investing. Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks. In response, from time to time, growth investing as an investment style may go out of favor with investors.

| General Stock Market [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | General Stock Market. Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). In addition, turbulence has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non‑performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market‑wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund’s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia’s invasion of Ukraine in February 2022 and the world‑wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non‑U.S. issuers that rely on the United States for trade. A fund’s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi‑governmental actions, among others. The active and expanding conflict in the Middle East between Israel and Hamas presents considerable market risks. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere.

| Non U S Securities [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | Non‑U.S. Securities. Investing in non‑U.S. securities may involve additional risks to those inherent in investing in U.S. securities, including exchange rate fluctuations, political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets.

| Developing Countries [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | Developing Countries. The Fund invests in developing countries, which include countries in the MSCI Emerging Markets (EM) index and other countries determined by the Adviser to be developing countries based on classifications made by the International Monetary Fund or on country characteristics similar to those of the countries in the EM index. Investments in developing countries are subject to all of the risks of non‑U.S. investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

| Small and Mid Sized Companies [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | Small‑ and Mid‑Sized Companies. The Adviser believes there is more potential for capital appreciation in small‑ and mid‑sized companies, but there also may be more risk. Securities of small‑ and mid‑sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small‑ and mid‑sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small‑ and mid‑sized companies rely more on the skills of management and on their continued tenure. Investing in small‑ and mid‑sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies.

| Large Shareholder Risk [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | Large Shareholder Risk. Certain shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund’s Shares. In addition, a third party investor, the Adviser or an affiliate of the Adviser, an authorized participant, a lead market maker, or another entity (i.e., a seed investor) may invest in the Fund and hold its investment solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. Any such investment may be held for a limited period of time. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund, including on the Fund’s liquidity. In addition, transactions by large shareholders may account for a large percentage of the trading volume on The NASDAQ Stock Market LLC (“NASDAQ”) and may, therefore, have a material upward or downward effect on the market price of the Shares.

| Technology [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | Technology. Technology companies, including internet‑related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.

| Risk [Text Block] | Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. | ||||||||||||||
| Risk Nondiversified Status [Member] | |||||||||||||||
| Prospectus [Line Items] | |||||||||||||||
| Risk [Text Block] | Non‑Diversified Portfolio. The Fund is non‑diversified, which means it may have a greater percentage of its assets in a single issuer than a diversified fund. Because of this, a non‑ diversified fund may invest a greater percentage of its assets in fewer issuers, and the performance of those issuers may have a greater effect on the performance of a non‑diversified fund versus a diversified fund. Thus, a non‑diversified fund is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period than a diversified fund.
