Current Market Value - CMV
  
You bought 100 shares of Apple stock at $100 per share. Which means your entry price was $10,000.
However, the shares are trading at $175 per share.
That makes the value of this trade (the current market value) $17,500. This is how much you could get if you sold it right now.
Let’s consider another example.
You buy a Corvette off the lot for $50,000 to compensate for something, um...small, or missing in your life. You drive that Corvette off the lot, and park it in your garage. Someone comes to your house and says they’ll give you $35,000 for it. You say “no way,” and call the dealership. They also tell you that the resale value now is $35,000.
No one said life was fair. But at least now it's unfair...with a Corvette in the garage.
