If you can move your account into a self directed one, having a balanced, diversified portfolio of funds, including bonds, is the best way to weather the volatility of the Trump era.
You would have to examine the prospectus of each fund, and likely have to drill down through several levels to determine which specific stocks are held. In my 457 plan with Fidelity when I click on a fund, it shows the percentage breakdown of types of companies whose stock is held (10% technologies, 15% energy, 12% retail, etc) and then a listing of the top 5-10 companies the fund holds stock in, such as Nvidia, Apple, Tesla, Exxon/Mobil, etc.
Unless a particular fund really loads up on SpaceX, its probably going to be hard to determine if they hold any shares. I recently rebalanced my 457, and reduced my holdings of funds that were overweighted (>15%) in tech stocks, or listed Tesla as one of their major holdings.
We can only do our best to tailor our investments to align with our values, and they dont make it easy.
Good Luck!
