Putnam Large Cap Growth Fund seeks capital appreciation. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fees and expenses | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The following tables describe the fees and expenses you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Putnam funds. More information about these and other discounts is available from your financial professional and in How do I buy fund shares? beginning on page 15 of the fund’s prospectus, in the Appendix to the fund’s prospectus, and in How to buy shares beginning on page II-1 of the fund’s statement of additional information (SAI). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Shareholder fees (fees paid directly from your investment) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Annual fund operating expenses (expenses you pay each year as a percentage of the value of your investment) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Example | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other 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 and that the fund’s operating expenses remain the same. Your actual costs may be higher or lower. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Portfolio turnover | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The fund pays transaction-related costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or the above example, affect fund performance. The fund’s turnover rate in the most recent fiscal year was 32%. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 32.00% | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Investments, risks, and performance | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Investments We invest mainly in common stocks of large U.S. companies, with a focus on growth stocks. Growth stocks are stocks of companies whose earnings are expected to grow faster than those of similar firms, and whose business growth and other characteristics may lead to an increase in stock price. We may consider, among other factors, a company’s valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell investments. Under normal circumstances, we invest at least 80% of the fund’s net assets (plus the amount of any borrowings for investment purposes) in companies of a size similar to those in the Russell 1000 Growth Index. This policy may be changed only after 60 days’ notice to shareholders. The fund is “non-diversified,” which means it may invest a greater percentage of its assets in fewer issuers than a “diversified” fund. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risks | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
It is important to understand that you can lose money by investing in the fund.
The value of investments in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic, political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes, outbreaks of infectious illnesses or other widespread public health issues, and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and reduced liquidity in the fund’s portfolio holdings, may negatively impact the fund’s performance, and may exacerbate other risks to which the fund is subject. Companies whose stocks we believe are undervalued by the market may have experienced adverse business developments or may be subject to special risks that have caused their stocks to be out of favor. Growth stocks may be more susceptible to earnings disappointments, and the market may not favor growth-style investing. From time to time, the fund may invest a significant portion of its assets in companies in one or more related industries or sectors, which would make the fund more vulnerable to adverse developments affecting those companies, industries or sectors. For example, the fund may invest a significant portion of its assets in companies in the information technology sector that may be significantly affected by technological obsolescence or innovation, short product cycles, falling prices and profits, competitive pressures and general market conditions. As a non-diversified fund, the fund may invest in fewer issuers and is more vulnerable than a more broadly diversified fund to fluctuations in the values of the securities it holds. There is no guarantee that the investment techniques, analyses, or judgments that we apply in making investment decisions for the fund will produce the intended outcome or that the investments we select for the fund will perform as well as other securities that were not selected for the fund. We, or the fund’s other service providers, may experience disruptions or operating errors that could negatively impact the fund. The fund may be an investment option for mutual funds that are managed by Franklin Resources, Inc. (“Franklin Templeton”) and its affiliates as “funds of funds” and other investors from time to time may make substantial investments in the fund. Such shareholders may at times be considered to control the fund. Dispositions of a large number of shares by these shareholders may adversely affect the fund’s liquidity and net assets. These redemptions may also force the fund to sell securities, which may increase the fund’s brokerage costs. The fund may not achieve its goal, and it is not intended to be a complete investment program. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Performance | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The performance information below gives some indication of the risks associated with an investment in the fund by showing the fund’s performance year to year and over time. The bar chart does not reflect the impact of sales charges. If it did, performance would be lower. Please remember that past performance is not necessarily an indication of future results.

Investments We invest mainly in common stocks (growth or value stocks or both) of large U.S. companies that we believe have favorable investment potential.
