Its actually pretty smart. People want the feel of holding a lot of shares. I'd rather say I own 20 shares of Google then just 1. Plus, many brokerages dont do fractional shares, so someone may have to wait a couple thousand dollars more just to buy 1 extra share. With that I'd rather just buy more shares of another solid tech company.
I'd rather be able to say I own one share of BRK.A than 20 shares of Alphabet.
It is all relative.
