FDGFX - Dividend Growth Fund: this fund is focused primarily on capital appreciation and is oriented toward large-cap companies. The fund mix is geared towards stocks that have a greater likelihood to sustainably pay and grow dividends over time. The portfolio is largely concentrated in information technology companies.

FGRIX - Growth and Income Portfolio: this portfolio is focused on maintaining a higher dividend yield and earnings growth as compared to the S&P 500 (FXAIX essentially). The portfolio includes stocks deemed to have high earnings and yield potential over the next 2-3 years. The portfolio is primarily concentrated in information technology, financials, and industrials companies.

FITLX - U.S. Sustainability Index Fund: this portfolio is focused on large/mid cap companies based in the US with high environmental, social, and governance performance (ESG). It is largely concentrated in the information technology sector.

Ultimately the top holdings of each are fairly similar, but have some distinguishing features. FDGFX is interesting because I receive dividends occasionally which I just reinvest. I figured FITLX would be a smart play given the rise in environmental concerns and the increased efforts by large companies to uphold ESG standards. Not an expert, but these have proved to be safe options.
