Roman numeral M is 1000. It is used at 1k sometimes. Frequently will see MM for million (thousand, thousand)

I put that there.

You are in the minority.

I am an Institutional Equities Trader... or was for almost 40 years. When trading large blocks of sticklike that, the M means 1,000. MM means a million.

The Roman numeral M is often used to indicate one thousand, and MM is used to indicate one million. For example, an expense of $60,000 might appear as $60M. Sales of $3,000,000 might be written as $3MM. Internet advertisers are familiar with CPM which is the cost per thousand impressions.
