This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PORTFOLIO TURNOVER </b></div>

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 its most recent fiscal year, the fund's portfolio turnover rate was 169% of the average value of its portfolio.

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PRINCIPAL INVESTMENT STRATEGIES </b></div>

The fund allocates its assets to a number of investment strategies (Strategies), through which the fund will take both physical and synthetic long positions and synthetic short exposures in a variety of equity and derivative instruments. The fund may hold significant synthetic long and short exposures. Each Strategy will be managed by a separate portfolio management team pursuant to allocations provided by the advisor from time to time. For long positions, the manager generally uses bottom-up fundamental analysis to identify companies throughout the world that the manager believes are undervalued or expects to experience high levels of growth. The manager also seeks to identify sectors, industries, or asset classes that may be overvalued or may experience low levels of growth, and the fund may take significant synthetic long and short exposures in such areas. The fund generally will not invest in companies with a market capitalization below $500 million at the time of purchase. The fund's synthetic short exposures will primarily be maintained in derivatives on exchange-traded pooled investment vehicles (e.g., exchange-traded funds (ETFs)) and/or indices, but may be maintained in other vehicles. In certain circumstances, the fund's overall synthetic short exposures may equal or exceed the size of the fund's long positions. Generally, the fund does not intend to take synthetic short exposures to individual stocks. The fund also may invest in master limited partnerships. The fund may trade securities actively.

Derivative instruments in which the fund may hold physical and synthetic long positions or synthetic short exposures include futures and forward contracts, such as interest-rate futures and foreign currency forward contracts; swaps, such as interest-rate swaps, credit default swaps, or total return swaps; call and put options; or warrants and rights, and may be used to reduce risk, obtain efficient market exposure, and/or enhance investment returns. The fund may also invest in repurchase agreements and reverse repurchase agreements.

The Strategies are typically diversified across sectors or focus on individual sectors, including financial services, healthcare, information technology, energy, biotechnology, and/or natural resources. Strategies and the allocations among them may vary. Each Strategy has a distinct investment philosophy and an analytical process based on a number of factors, such as business environment, management quality, balance sheet, income statement, anticipated earnings, expected growth rates, revenues, dividends, and other measures of value. As a result, the aggregate portfolio will represent a wide range of investment philosophies, companies, industries, and market capitalizations.

The manager may also invest in debt instruments, including high yield debt instruments (i.e., junk bonds). Such instruments may include, but are not limited to, bonds, bank loans (including loan participations), asset-backed securities, mortgage-backed securities, convertible securities, foreign currency-denominated foreign securities, U.S. and foreign government securities, hybrid securities (including convertible bonds, contingent convertible/capital securities, and similarly structured securities), derivatives, currencies, and reverse repurchase agreements. Some loans may be illiquid. Derivative instruments also may magnify the fund's gains and losses. The fund's derivative transactions will be fully collateralized.

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"><b> PRINCIPAL RISKS </b></div>

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.

During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.

Biotechnology industry risk. Biotechnology companies are subject to regulatory requirements, intense competition, rapid technological and other developments that could negatively affect the price, profitability, viability, and availability of their products and services. Investments in this industry are often based on speculation regarding future research and product developments.

Convertible securities risk. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.

Credit and counterparty risk. The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.

Cybersecurity and operational risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.

Energy sector risk. The energy sector is cyclical and highly dependent on commodities prices, which may be volatile. The market value of energy companies can be significantly affected by a number of factors, including global energy price volatility, supply and demand, exchange- and interest-rate fluctuation, and domestic and foreign political and economic developments. Energy companies also face a significant risk of civil liability.

Equity securities risk. The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Growth company securities may fluctuate more in price than other securities because of the greater emphasis on earnings expectations. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.

Exchange-traded funds risk. An ETF generally reflects the risks of the underlying securities of the index it is designed to track. However, at times, an ETF's portfolio composition and performance may not match that of such index. A fund bears ETF fees and expenses indirectly.

Financial services sector risk. Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.

Foreign securities risk. Less information may be publicly available regarding foreign issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets.

Hong Kong Stock Connect Program (Stock Connect) risk. China A-Shares listed and traded on certain Chinese stock exchanges through Stock Connect, a mutual market access program designed to, among other things, enable foreign investment in the People's Republic of China (PRC) via brokers in Hong Kong, are subject to a number of restrictions imposed by Chinese securities regulations and local exchange listing rules. Because Stock Connect was established in November 2014, developments are likely, which may restrict or otherwise affect the fund's investments or returns. Furthermore, any changes in laws, regulations and policies of the China A-Shares market or rules in relation to Stock Connect may affect China A-Share prices. These risks are heightened by the underdeveloped state of the PRC's investment and banking systems in general.

Healthcare sector risk. Health sciences companies may be significantly affected by product obsolescence, thin capitalization, limited product lines and markets, civil liability claims, and legislative or regulatory activities, among other factors.

Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund's volatility and could produce disproportionate losses, potentially more than the fund's principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Regulatory changes in derivative markets could impact the cost of or the fund's ability to engage in derivative transactions. Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, options, interest rate swaps, total return swaps, reverse repurchase agreements, and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund's ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund's net asset value per share (NAV).

High portfolio turnover risk. Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.

Hybrid instrument risk. Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies.

Information technology risk. Information technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.

Large company risk. Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.

Leveraging risk. Using derivatives may result in a leveraged portfolio. Leveraging long exposures increases a fund's losses when the value of its investments declines. Some derivatives have the potential for unlimited loss, regardless of the size of the initial investment.

Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.

Loan participations risk. Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Master limited partnership risk. MLPs generally reflect the risks associated with their underlying assets and with pooled investment vehicles. MLPs with credit-related holdings are subject to interest-rate risk and risk of default.

Mortgage-backed and asset-backed securities risk. Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.

Natural resources industry risk. The natural resources industry can be significantly affected by international political and economic developments, energy conservation and exploration efforts, commodity prices, and taxes and other governmental regulations, among other factors.

Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.

Small and mid-sized company risk. Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.

Synthetic short exposure risk. The fund will gain synthetic short exposure through a forward commitment through a swap agreement. Synthetic short exposures involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment.

Technology companies risk. Technology companies can be significantly affected by rapid obsolescence, short product cycles, competition, and government regulation, among other factors. Investments in the technology sector may be susceptible to heightened risk of cybersecurity breaches, which may allow an unauthorized party to gain access to personally identifiable information and other customer data.

Warrants risk. The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291 (Class A and Class C), Monday to Thursday, 8:00 A.M.—7:00 P.M., and Friday, 8:00 A.M.—6:00 P.M., Eastern time, or 888-972-8696 (Class I and Class R6) between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days.

A note on performance

Class A and Class C shares commenced operations on December 20, 2013, and May 16, 2014, respectively. Returns prior to Class C shares' commencement date are those of Class A shares, except that they do not include Class A sales charges and would be lower if they did. Returns for Class C shares would have been substantially similar to returns of Class A shares because both share classes are invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.

[1] (on certain purchases, including those of $1 million or more)

[1] The advisor contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement. This waiver is allocated proportionally among the participating funds. During its most recent fiscal year, the fund's reimbursement amounted to 0.01% of the fund's average daily net assets. This agreement expires on June 30, 2020, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.
