Missing 401(k) dividends
Your investment is probably in a Collective Investment Trust. These are not mutual funds, and are not publicly traded. I.e. they are private to plan participants in your company. Because of this, they are not required* to distribute dividends like mutual funds. Instead, they will reinvest dividends automatically, increasing the value of the fund, rather than number of shares, as with dividend reinvestment. Sine you mention the S&P 500 fund you have tracks closely to the S&P Index, keep in mind there's two indexes you could be looking at: Without any new contributions, your fund should closely track the Total Return version for periods 3 months or longer, minus the expense ratio. If you are adding contributions to the fund, you can't just look at the start and end balances. The comparison is trickier and you'll need to use the Internal Rate of Return (look into the XIRR function in Excel/Google Sheets). *MFs are not strictly required to pay dividends, but are strongly tax-incentivized to do so, and essentially all do.
