| Performance Narrative [Text Block] |
The
following bar chart and table provide some indication of the risks of investing in the fund. The bar
chart shows changes in the performance of the fund's Class Z shares from year to year. Sales charges,
if any, are not reflected in the bar chart, and, if those charges were included, returns would have been
less than those shown. The table compares the average annual total returns of the fund's shares to those
of the Russell 1000® Index, a broad measure
of relevant market performance, and the Russell 1000®
Growth Index. The fund's past performance (before and after taxes) is not necessarily an indication
of how the fund will perform in the future. Performance for each share class will vary due to differences
in expenses. More recent performance information may be available at www.bny.com/investments.
