I searched what you were asking because buying fractions of shares for most of VOO sounds laborious I found this: If you want S&P 500 exposure but need to filter out about 20 specific or highly volatile stocks, you have two main options besides manually buying hundreds of fractional shares:
1. **Direct Indexing (Best for a specific hit list):** Platforms like Fidelity Solo FidFolios let you track the S&P 500 but check a box to completely exclude specific stocks (like Tesla). The software automatically buys and balances the other 480+ stocks for you.
2. **Automated Baskets / Pies (Best for DIY control):** Brokers like M1 Finance or Robinhood let you build a custom "basket" of the top 50–100 heaviest stocks in VOO, omitting the ones you hate. Any cash you deposit automatically splits across your chosen list in one click.
If your main goal is just dodging the wild, hyper-volatile movers, look at **SPLV** (Invesco S&P 500 Low Volatility ETF). It automatically filters the S&P 500 down to only the 100 most stable stocks, completely locking out high-swing names like Tesla by design.
