EXAMPLE

The following example is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds. The example assumes
that you invest $10,000.00 in the Fund for the time periods indicated, that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same.

Although your actual costs may be higher or lower, based on these assumptions you would pay the following expenses whether or not you redeemed your shares at the end of each period:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
Alger Growth Opportunities Fund Class I	137	654	1,198	2,684

PORTFOLIO TURNOVER

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 examples, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was 66.59% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY

Fred Alger Management, Inc. believes companies undergoing Positive Dynamic
Change offer the best investment opportunities. Positive Dynamic Change refers
to companies realizing High Unit Volume Growth or companies undergoing Positive
Lifecycle Change. High Unit Volume Growth companies are traditional growth
companies experiencing, for example, significantly growing demand or market
dominance. Positive Lifecycle Change companies are, for example, companies
benefitting from regulatory change, a new product introduction or management
change.

The Fund invests primarily in the stock of small, fast-growing companies that
Fred Alger Management, Inc. believes offer innovative products, services or
technologies to a rapidly-expanding marketplace. Although the Fund may invest
without limit in companies of any size, the Fund focuses on companies that, at
the time of purchase of the securities, have a total market capitalization not
exceeding the highest market capitalization of companies included in the Russell
2500 Growth Index, as reported by the index as of the most recent quarter-end.
This index is designed to track the performance of small and medium
capitalization stocks. At December 31, 2011, the highest market capitalization
of the companies in this index was $9.5 billion.

The Fund can leverage, that is, borrow money to buy additional securities. By
borrowing money, the Fund has the potential to increase its returns if the
increase in the value of the securities purchased exceeds the cost of borrowing,
including interest paid on the money borrowed.

The Fund can also invest in derivative instruments. The Fund currently expects
that its primary uses of derivatives will involve: (1) purchasing put and call
options and selling (writing) covered put and call options, on securities and
securities indexes, to increase gain, to hedge against the risk of unfavorable
price movements in the underlying securities, or to provide diversification of
risk, and (2) entering into forward currency contracts to hedge the Fund's
foreign currency exposure when it holds, or proposes to hold, non-U.S. dollar
denominated securities.

PRINCIPAL RISKS

As with any fund that invests in stocks, your investment will fluctuate in value,
and the loss of your investment is a risk of investing. The Fund's price per share
will fluctuate due to changes in the market prices of its investments. Also, the
Fund's investments may not grow as fast as the rate of inflation and stocks tend
to be more volatile than some other investments you could make, such as bonds.

Prices of growth stocks tend to be higher in relation to their companies'earnings
and may be more sensitive to market, political and economic developments than
other stocks, making their prices more volatile. An investment in the Fund may be
better suited to investors who seek long-term capital growth and can tolerate
fluctuations in their investment's value.

A small investment in derivatives could have a potentially large impact on the
Fund's performance. When purchasing options, the Fund bears the risk that if the
market value of the underlying security does not move to a level that would make
exercise of the option profitable, the option will expire unexercised. When a
call option written by the Fund is exercised, the Fund will not participate in
any increase in the underlying security's value above the exercise price. When a
put option written by the Fund is exercised, the Fund will be required to
purchase the underlying security at a price in excess of its market value. Use
of options on securities indexes is subject to the risk that trading in the
options may be interrupted if trading in certain securities included in the
index is interrupted, the risk that price movements in the Fund's portfolio
securities may not correlate precisely with movements in the level of an index,
and the risk that Fred Alger Management, Inc. may not predict correctly
movements in the direction of a particular market or of the stock market
generally. Because certain options may require settlement in cash, the Fund may
be forced to liquidate portfolio securities to meet settlement obligations.
Forward currency contracts are subject to currency exchange rate risks, the risk
of non-performance by the contract counterparty, and the risk that Fred Alger
Management, Inc. may not predict accurately future foreign exchange rates.

The following risks also apply:

• the possibility of greater risk by investing in companies with small or medium
market capitalizations rather than larger, more established issuers owing to
such factors as more limited product lines or financial resources or lack of
management depth.

• the cost of borrowing money to leverage will exceed the returns for the
securities purchased or the securities purchased may actually go down in value;
thus the Fund's net asset value could decrease more quickly than if it had not
borrowed.

• it may be difficult or impossible to liquidate a security position at a time
and price acceptable to the Fund owing to the potentially less frequent trading
of stocks of smaller market capitalization.

PERFORMANCE

The following bar chart and the table beneath it provide 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 for the indicated
periods compare with those of an appropriate benchmark of market performance.
Remember that a Fund's past performance (before and after taxes) is not
necessarily an indication of how it will perform in the future. Updated
performance information is available on the Fund's website www.alger.com.

In the foregoing table, after-tax returns are calculated using the historical
highest individual federal marginal income tax rates and do not reflect the
impact of state and local taxes. Actual after-tax returns depend on an
investor's tax situation and may differ from those shown. The after-tax returns
shown may not be relevant to investors who hold their Fund shares through
tax-deferred arrangements, such as 401(k) plans or individual retirement
accounts. A "return after taxes on distributions and sale of fund shares" may
sometimes be higher than the other two return figures; this happens where there
is a capital loss on redemptions, giving rise to a tax benefit to the
shareholder.

[1] Fred Alger Management, Inc. has contractually agreed to reimburse Fund expenses through February 28, 2013 to the extent necessary to limit the annual operating expenses of Class I Shares of the Fund to 1.35% of the Fund's average net assets (excluding interest, taxes, brokerage and extraordinary expenses). This expense reimbursement cannot be terminated.
