A NEW APPROACH TO GROWTH STOCK INVESTING
SELECT EQUITY TRUSTS
Achieving financial success in today's dynamic marketplace depends on SELECTING
the right strategy. As new opportunities emerge, sparked by changing business
trends, investing must be geared to capitalize on them. The purchase of a
professionally selected "basket" of growth stocks can help minimize the risks
associated with investing in individual securities.
THE STRATEGIC GROWTH LARGE-CAP PORTFOLIO 99-1
Identifying stocks with the potential for above average increases in price
appreciation, without significantly increasing your risk, is a challenge posed
by the growth style of investing. The STRATEGIC GROWTH LARGE-CAP PORTFOLIO is a
Unit Investment Trust combining a disciplined investment approach with an
exclusive Stock Selection Model.
AN EXCLUSIVE STRATEGY FOR SELECTING GROWTH
Through technical screening of the S&P 500 Index*, the Selection Model uses
analysts' estimates to quantify the upward trends in earnings and price
momentum. The common stocks of 15 large-cap growth companies with above average
capital appreciation potential for the next twelve months are chosen for the
Trust's portfolio.
SHORT-TERM LIFE
The Trust will terminate in approximately one year. The portfolio will then
either be liquidated or distributed to unitholders in-kind at their election.
You may, of course, sell or redeem your units prior to the Trust's termination.
REINVESTMENT OPTION
Investors may elect to have distributions automatically reinvested in additional
units of the Trust subject to the then-remaining deferred sales charge.
NO TURNOVER
The Trust typically has no turnover during its life. Unitholders know exactly
where their money is invested. Managed investment portfolios may have very high
turnover rates over a one-year period.
LIQUIDITY
All or a portion of your units may be liquidated at any time, based on net asset
value (including deduction for any unpaid deferred sales charge). The price you
receive will reflect market conditions and could be more or less than the price
originally paid. Investors may at termination choose to receive their share of
the Trust's actual underlying securities.
NO MARKET TIMING
The STRATEGIC GROWTH LARGE-CAP PORTFOLIO leaves "emotional trading" behind by
focusing and buying a portfolio of 15 large-cap S&P 500 Index stocks. Due to the
Trust's "buy and hold" strategy, an investor's money is generally invested at
all times. Managed investment vehicles buy and sell securities and may have a
sizable percentage of assets in cash.
ROLLOVER OPTIONS
Investors, in connection with the Trust's termination, may elect to roll over
their investment into units of a new series, if offered, subject only to the
deferred sales charge. There are two rollover options available to unitholders:
(1) The TAX-DEFERRED ROLLOVER feature enables investors to defer any capital
gains on stocks which are carried over into the next portfolio
(2) Investors holding qualified accounts (e.g., IRA-2000), or those preferring
not to defer tax consequences, may elect the TRADITIONAL, NON-TAX DEFERRED
ROLLOVER.
RISKS AND OTHER CONSIDERATIONS
An investment in units of a Trust should be made with an understanding of the
risks of investing in a fixed portfolio of common stocks, chosen at the time of
the Trust's formation, which is not expected to change over the life of the
Trust, including: price fluctuation, volatility, and increased risks inherent in
equity securities such as the Trust's, which are chosen based on growth and
price momentum. Your risk is increased because your capital may be considered to
be concentrated in stock of companies in the retail industry. Although each
Trust is a one-year investment, the strategy is long-term and investors should
consider reinvesting in successive trusts. Unless held in an IRA or other
tax-advantaged account, there may be current tax consequences associated with
this investment.
This investment is not appropriate for those investors not willing to assume the
increased risks of a growth strategy, nor for those seeking preservation of
capital or current income. It is not designed to be a complete equity investment
program.
