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.
| Share class | 1 year | 3 years | 5 years | 10 years |
| Class A | $671 | $875 | $1,096 | $1,729 |
| Class B | $678 | $851 | $1,149 | $1,864 |
| Class B (no redemption) | $178 | $551 | $949 | $1,864 |
| Class C | $278 | $551 | $949 | $2,062 |
| Class C (no redemption) | $178 | $551 | $949 | $2,062 |
| Class M | $497 | $807 | $1,140 | $2,078 |
| Class R | $127 | $397 | $686 | $1,511 |
| Class T | $349 | $560 | $789 | $1,444 |
| Class Y | $77 | $240 | $417 | $930 |

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 76%.
Investments, risks, and performance
Investments
We invest mainly in common stocks of U.S. companies of any size, with a focus on growth stocks. Growth stocks are issued by 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.
Risks
It is important to understand that you can lose money by investing in the fund.
The value of stocks in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general financial market conditions, changing market perceptions, changes in government intervention in the financial markets, and factors related to a specific issuer or industry. These and other factors may lead to increased volatility and reduced liquidity in the fund’s portfolio holdings. Growth stocks may be more susceptible to earnings disappointments, and the market may not favor growth-style investing. These risks are generally greater for small and midsize companies. 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 industries or sectors.
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. Monthly performance figures for the fund are available at putnam.com.

After-tax returns
reflect the historical highest individual federal marginal income tax rates and do not reflect state and local taxes. Actual after-tax
returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are shown for class A shares
only and will vary for other classes. These after-tax returns do not apply if you hold your fund shares through a 401(k) plan,
an IRA, or another tax-advantaged arrangement.
Class B share performance reflects conversion to class A shares after eight years.

Financial intermediary compensation
If you purchase the fund through a broker/dealer or other financial intermediary (such as a bank or financial advisor), the fund and its related companies may pay that intermediary for the sale of fund shares and related services.
