What are fractional shares and why do they matter for new investors?

Fractional shares let you buy a slice of a stock or ETF by dollar amount instead of by whole shares, so you can invest $50 in a fund whose share price is $400. This matters because it removes the price barrier — you can build a diversified portfolio with small, regular contributions and put every dollar to work instead of leaving cash idle. Most major brokers (Fidelity, Schwab) now support fractional buying on stocks and ETFs. It's especially useful for automatic investing: you can set $200 a month to flow into a fund regardless of its share price. Note that a few brokers limit fractional trading to market hours or certain securities, and selling a fractional position may take an extra step. For dollar-cost averaging into index funds, fractional shares make consistent investing far easier.
