| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the twelve months ended September 30, 2024, the Fund returned 32.86% The Fund underperformed its benchmark, the S&P 500 Index, which returned 36.35% for the same period. What Factors Influenced Performance During the last twelve months in the markets the only three things that mattered were inflation, inflation and inflation. Inflation soared from 2019 – 2022, which triggered the Federal Reserve Open Market Committee (FMOC) to increase interested rates eleven times from March 2022 thru July 2023. These increases helped to tamp down inflation to the point where the FOMC decided to have its first cut since the Covid-19 pandemic. In the Advisor’s opinion, lowering inflation to a level that is very close to the FOMC goal of 2.0% was a major macro-economic reason for the strong 12 month returns. As outlined in the prospectus, the Advisor’s strategy is to overweight the Fund’s portfolio into the eleven macro-economic sectors that, as a whole, construct the entire US economy. During the reporting period the top two sectors were information technology and communication services. The Fund’s top two holdings within those sectors, as of September 30, 2024, were Vanguard Information Technology (VGT) and Vanguard Communication Services (VOX). The bottom two sectors were health care and energy. The Fund’s performance was hindered by a 7.41% [increase/decrease] in health care. The past twelve months proved to be strong regardless of the multiple foreign wars and the uncertainty that comes with a US Presidential election. This is a testament to how meaningful inflation can be on the markets. |
