I am not sure specifically about what you are asking and would like to hear on this myself but I don't believe there is any disadvantage per se because I know there are programs that do dividend reinvestment and that results in
fractional ownership of a
share until it becomes a full
share and while only your «whole»
shares are «traded» when it
comes to actual worth, your
fractional count too, so I assume from that if you had «whole»
shares no matter what the amount, you'd be proportionally invested as anyone owning more
shares, just to a lesser extent.
