The US market offers fractional shares, which means you can buy a fraction of a share which allows you to own an exact dollar amount of a company or ETF. No more worrying about exact multiples or finding enough money to buy a share worth $150,000.
For example, if you want to buy $5000 of a share, whose share price is $315.98 at the time of execution, you will own 15.82 shares.
On Stake, you can buy or sell in any dollar amount you want, from $10 to $500,000. Your orders don't need to be a multiple of the share price at the time.
