Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period?

Stocks continued positive momentum through the 2nd quarter to post strong first-half gains. While the large cap S&P 500 was again the leader, a small group of stocks in the index delivered most of the outperformance. Nvidia has almost singlehandedly pushed the S&P 500 far beyond the results of other global indices year to date (YTD). As the size of Nvidia grew, the representation in the TOPS portfolios also increased. Fortunately, in the case of NVIDIA, this has richly rewarded our investors. Nvidia represents roughly 12% of the exposure in the SPDR Portfolio S&P 500 Growth ETF, a top holding in the TOPS allocations. The Barclay’s U.S. Aggregate Bond Index finished the first half slightly negative. However, the bond positioning in the Portfolios has significantly benefited investors, as the portfolio management team's portfolio decisions resulted in a positive return YTD for fixed income, outperforming the index by about 1%, depending on the portfolio. Most equities remain positive for the year. Growth stocks (S&P 500 Growth) are outperforming value stocks (S&P 500 Value), returning +23.6% and +5.8%, respectively. Midcap (S&P 400, +6.2%) has outperformed small cap (S&P 600, -0.7%) year-to-date. Emerging markets (MSCI Emerging Markets) have returned +7.5%, outpacing developed international (MSCI EAFE), which has returned +5.3%. Natural resources (S&P GSSI NA Natural Resources, +9.6%) is up for the year, while real estate (MSCO World Real Estate, -3.0%) is down so far this year.

Year-to-date, the Barclay’s US TIPS Index had a +0.7% return, while the Barclay’s US Aggregate Bond Index was down -0.7%. Credit (ICE BofA US Corporate Index, +0.0%) has outperformed government (ICE BofA US Treasury Index, -0.8%) so far this year. Investment grade corporates (iBoxx USD Liquid Investment Grade Index, -1.2%) and international bond indexes (Bloomberg Global Aggregate ex-USD, -0.3%) are negative on the year, while high yield (Solactive USD High Yield Corporates, +2.2%) is positive. The 10-year US Treasury yield increased from 3.88% to 4.36% in the first half of the year.
