Mine and Yours
What it is:
"Mine" and "yours" are colloquial references to buy and sell transactions.
How it works (Example):
Buy and sell trades are a cornerstone of the capital market. Traders use the terms "mine" and "yours" to indicate a desire to buy or sell securities, respectively. For example, a trader might tell another trader "it's mine" to indicate that he or she wishes to purchase a stock from a person who wishes to sell it.
