PERFORMANCE

| Performance Narrative [Text Block] |
The following bar chart and performance table provide an
indication of the risks of investing in the Fund. The bar chart shows the changes in the performance of the Fund from year to year over
a period of 10 years. The performance table shows how the average annual total returns of the Fund, over certain periods of time, compared
to those of a broad-based market index (the Standard & Poor’s 500 Index) and a technology sector-heavy index (the NASDAQ Composite
Index). Though not explicitly a technology sector index, the NASDAQ Composite Index was selected for comparison because it is widely recognized
as a technology sector benchmark, given the concentration of technology companies in the index. The Fund’s past performance (before
and after taxes) is no guarantee of how it will perform in the future.

PERFORMANCE
|

a period of 10 years. The performance table shows how the average annual total returns of the Fund, over certain periods of time, compared
to those of a broad-based market index (the Standard & Poor’s 500 Index), as well as a technology sector-heavy index (the NASDAQ
Composite Index) and an alternative energy sector-focused index (the WilderHill Clean Energy Index). Though not explicitly a technology
sector index, the NASDAQ Composite Index was selected for comparison because it is widely recognized as a technology sector benchmark,
given the concentration of technology companies in the index. The WilderHill Clean Energy Index was selected for comparison because it
is an index of companies involved in clean energy (e.g., solar, wind, geothermal) and energy conservation. The Fund’s past
performance (before and after taxes) is no guarantee of how it will perform in the future.
