| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The tables below describe the sales charges, fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and an eligible group of investors purchase, or agree to purchase in the future, $25,000 or more in shares of the Fund or other funds in the Prudential Investments family of funds. More information about these discounts is available from your financial professional and is explained in Reducing or Waiving Class A's Initial Sales Charge on page 23 of the Fund's Prospectus and in the Fund's Statement of Additional Information (SAI), in Rights of Accumulation on page 53. | |||||||||

| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 37% of the average value of its portfolio. | |||||||||

The decision on whether to renew, modify or terminate the waiver is subject to review by the Distributor and the Fund's Board of Directors. | |||||||||
| Strategy [Heading] | rr_StrategyHeading | INVESTMENTS, RISKS AND PERFORMANCE Principal Investment Strategies. |
|||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund seeks investments whose prices will increase as well as pay the Fund dividends and other income. We normally invest at least 80% of the Fund's investable assets in equity and equity-related and investment-grade debt securities of utility companies. The term “investable assets” refers to the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund will provide 60 days' prior written notice to shareholders of a change in its non-fundamental policy of investing at least 80% of its investable assets in the type of investment suggested by its name. Utility companies, based on the Global Industry Classification Standard (GICS) industry classifications, as they may be amended from time to time, include electric utilities, gas utilities, water utilities, multi-utilities, independent power producers, diversified telecommunication services, wireless telecommunication services, transportation infrastructure, energy equipment and services and oil, gas and consumable fuels. Some of these securities are issued by foreign companies. We may invest more than 5% of the Fund's assets in any one issuer. The Fund participates in the initial public offering (IPO) market. Securities purchased in IPOs may be very volatile, rising and falling rapidly, often based, among other reasons, on investor perceptions rather than on economic factors. Additionally, investments in IPOs may disproportionately affect (positively or negatively) the Fund’s performance if the fund has a small asset base. In deciding which stocks to buy, we use what is known as a value investment style. That is, we invest in stocks that we believe are undervalued, given the company's earnings, cash flow or asset values. We look for catalysts that will help unlock inherent value. A number of conditions can warrant the sale of an existing position, including (1) the stock has reached its price target; (2) subsequent events invalidate our investment thesis; (3) the catalysts we expected to narrow the gap between the stock price and what we believe to be the true worth of the company have passed or no longer exist; or (4) the stock price declines to below what we had thought to be the reasonable worst-case scenario. While we make every effort to achieve our objective, we can't guarantee success. |

| Strategy Portfolio Concentration [Text] | rr_StrategyPortfolioConcentration | We normally invest at least 80% of the Fund's investable assets in equity and equity-related and investment-grade debt securities of utility companies. | |||||||||
| Risk [Heading] | rr_RiskHeading | Principal Risks of Investing in the Fund. | |||||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment. Recent Market Events. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the crisis, the U.S. and other governments and U.S. and foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. Risk of Increase in Expenses. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Utility Sector Risk. Utility sector risk is the risk that the Fund's concentration in the securities of companies in the utility sector or industry may cause the Fund to be more exposed to the price movements of such companies than a more broadly diversified fund. The Fund will perform poorly during a downturn in the utility sector. The Fund's also is subject to risks of the utility industry, such as inflation and regulatory changes, due to its concentration in utility securities. When interest rates go up, the value of securities issued by utility companies historically has gone down. Although the average dividend yield of utility industry stocks has been higher than those of other companies, the total return of utility securities has historically underperformed those of industrial companies. In most countries and localities, the utility industry is regulated by governmental entities, which can increase costs and delays for new projects and make it difficult to pass increased costs on to consumers. In certain areas, deregulation of utilities has resulted in increased competition and reduced profitability for certain companies, and increased the risk that a particular company will become bankrupt or fail completely. Reduced profitability, as well as new uses for or additional need of funds (such as for expansion, operations or stock buybacks), could result in reduced dividend payout rates for utility companies. In addition, utility companies face the risk of increases in the cost and reduced availability of fuel (such as oil, coal, natural gas or nuclear energy) and potentially high interest costs for borrowing to finance new projects. As a sector fund, the Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance indexes. Equity and Equity-Related Securities Risks. There is the risk that the value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. The Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments. The Fund may invest in companies that reinvest their earnings rather than distribute them to shareholders. To the extent the Fund does invest in such companies, the Fund is not likely to receive significant dividend income on its portfolio securities. Market Risk. The securities markets are volatile and the market prices of the Fund’s securities may decline generally. Securities fluctuate in price based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline. Value Style Risk. Since the Fund follows a value investment style, there is the risk that the value style may be out of favor for a period of time, that the market will not recognize a security's intrinsic value for a long time or that a stock judged to be undervalued may actually be appropriately priced. Historically, value stocks have performed best during periods of economic recovery. Foreign Securities Risk. The Fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the Fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the Fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability. Lack of information may also affect the value of these securities. We do not consider American Depositary Receipts (“ADRs”), American Depositary Shares (“ADSs”) and other similar receipts or shares traded in U.S. markets in which the Fund may invest to be foreign securities. Currency Risk. The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. Credit Risk. This is the risk that the issuer, the guarantor or the insurer of a fixed-income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, the securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The longer the maturity and the lower the credit quality of a bond, the more sensitive it is to credit risk. Nondiversification Risk. The Fund is nondiversified. This means that the Fund may invest a greater percentage of its assets in the securities of a single company or other issuer than a diversified fund. Investing in a nondiversified fund involves greater risk than investing in a diversified fund because a loss resulting from the decline in value of any one security may represent a greater portion of the total assets of a nondiversified fund. Management Risk. The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect. Initial Public Offerings Risk. The Fund may participate in the initial public offering (IPO) market. The volume of IPOs and the levels at which the newly issued stocks trade in the secondary market are affected by the performance of the stock market overall. If IPOs are brought to the market, availability may be limited and if the Fund desires to acquire shares in such an offering, it may not be able to buy any shares at the offering price, or if it is able to buy shares, it may not be able to buy as many shares at the offering price as it would like. The prices of securities involved in IPOs are often subject to greater and more unpredictable price changes than more established stocks. Such unpredictability can have a dramatic impact on the Fund's performance (higher or lower) and any assumptions by investors based on the affected performance may be unwarranted. In addition, as Fund assets grow, the impact of IPO investments on performance will decline, which could reduce total returns.

| Expense [Heading] | rr_ExpenseHeading | FUND FEES AND EXPENSES | |||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The tables below describe the sales charges, fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and an eligible group of investors purchase, or agree to purchase in the future, $25,000 or more in shares of the Fund or other funds in the Prudential Investments family of funds. More information about these discounts is available from your financial professional and is explained in Reducing or Waiving Class A's Initial Sales Charge on page 24 of the Fund's Prospectus and in the Fund's Statement of Additional Information (SAI), in Rights of Accumulation on page 53. | |||||||||

| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 63% of the average value of its portfolio. | |||||||||

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same and that all dividends and distributions are reinvested. Your actual costs may be higher or lower. | |||||||||

This waiver may not be terminated prior to March 31, 2014. The decision on whether to renew, modify or terminate the waiver is subject to review by the Distributor and the Fund's Board of Directors. | |||||||||
| Strategy [Heading] | rr_StrategyHeading | INVESTMENTS, RISKS AND PERFORMANCE Principal Investment Strategies. |
|||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund seeks investments whose prices will increase over time. The Fund normally invests at least 80% of its investable assets in equity and equity-related securities of companies within the financial services sector, such as banks, savings and loan associations (and other thrifts), mortgage banking companies, finance companies, insurance companies, securities/brokerage firms, asset management companies, securities exchanges, leasing companies and consumer and industrial finance companies, and other companies that are primarily engaged in providing financial services. The term “investable assets” refers to the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. We refer to the group of industries in which the Fund concentrates as its “sector.” The Fund will invest in securities of issuers among a number of different countries throughout the world, one of which may be the United States. However, the Fund has no limit on the amount of assets that must be invested in each country. The Fund’ s investments in the securities of non-U.S. issuers, which we refer to as “foreign securities,” include stocks and other equity-related securities. The Fund may participate in the initial public offering (“IPO”) market. Securities purchased in initial public offerings may be very volatile, rising and falling rapidly, often based, among other reasons, on investor perceptions rather than on economic factors. Additionally, investments in IPOs may magnify the Fund’s performance if it has a small asset base. The Fund will provide 60 days' prior written notice to shareholders of a change in its non-fundamental policy of investing at least 80% of its investable assets in the type of investment suggested by its name. While we make every effort to achieve the Fund's investment objective, we can't guarantee success. |

| Strategy Portfolio Concentration [Text] | rr_StrategyPortfolioConcentration | The Fund normally invests at least 80% of its investable assets in equity and equity-related securities of companies within the financial services sector, such as banks, savings and loan associations (and other thrifts), mortgage banking companies, finance companies, insurance companies, securities/brokerage firms, asset management companies, securities exchanges, leasing companies and consumer and industrial finance companies, and other companies that are primarily engaged in providing financial services. | |||||||||
| Risk [Heading] | rr_RiskHeading | Principal Risks of Investing in the Fund. | |||||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment. Recent Market Events. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the crisis, the U.S. and other governments and U.S. and foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. Risk of Increase in Expenses. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Sector Risk. The Fund is subject to risks within its own sector because it concentrates its investments in securities of companies within that sector's industries. For example, the Fund can be most adversely affected by legislative changes, increased competition, general economic conditions and financial market disruptions. The prices of the securities in which the Fund invests can be volatile. Since the Fund is a sector fund, its holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of the indexes. Equity and Equity-Related Securities Risks. There is the risk that the value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. The Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments. The Fund may invest in companies that reinvest their earnings rather than distribute them to shareholders. To the extent the Fund does invest in such companies, the Fund is not likely to receive significant dividend income on its portfolio securities. Market Risk. The securities markets are volatile and the market prices of the Fund’s securities may decline generally. Securities fluctuate in price based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline. Foreign Securities Risk. The Fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the Fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the Fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability. Lack of information may also affect the value of these securities. We do not consider American Depositary Receipts (“ADRs”), American Depositary Shares (“ADSs”) and other similar receipts or shares traded in U.S. markets in which the Fund may invest to be foreign securities. Management Risk. The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect. Nondiversification Risk. The Fund is nondiversified. This means that the Fund may invest a greater percentage of its assets in the securities of a single company or other issuer than a diversified fund. Investing in a nondiversified fund involves greater risk than investing in a diversified fund because a loss resulting from the decline in value of any one security may represent a greater portion of the total assets of a nondiversified fund. Currency Risk. The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. For more information on the risks of investing in this Fund, including the risks of investing in foreign securities, please see How the Fund Invests—Investment Risks in the Prospectus and Investment Risks and Considerations in the SAI. |
