Fractional shares are slices of individual stock shares. Fractional shares enable smaller dollar size portfolios to invest in more companies than if only whole shares were offered. Follow's Investment Advisory affiliate (IA) accepts accounts as small as $5 and will buy or maintain a position in a security if the security position is valued at 10 cents or more. Fractional shares allow you to invest in your Follow IA account by dollar amount, rather than by whole shares of different stocks.
