Amazon, now Alphabet shares at $US1,000+

Google parent Alphabet joins the few elite companies whose stocks are trading above $US1,000, joining Amazon which reached the milestone last week.

Alphabet's stock has surpassed the $US1,000 mark for the first time, less than a week after Amazon's shares reached the same milestone.

Google's parent is among the few companies that have been reluctant to split their stock. Those splits make a company's stock more affordable and generate brokerage fees.

But companies like online retail juggernaut Amazon and Alphabet have chosen to reward its long-term investors.

Shares of Alphabet Inc, which is based in Mountain View, California, and trades on the Nasdaq, gained $US7.76, or around 0.8 per cent, to close at $1,003.88 on Monday.

Nasdaq listed Amazon breached the $US1,000 mark last Tuesday.
