Here's the example scenario they're using to illustrate P/L:

For example, let’s say that on the first trading day of the year you start with $100,000 in your account and no open positions. You then buy 500 shares each of ABC and XYZ stock, both of which are trading for $10.00. Assuming both stocks immediately go up $1, your profit/loss would look like this:

Now let’s say the following day, shares of ABC drop 50 cents per share, and you decide to sell it. Meanwhile, the XYZ share price was unchanged. Your P/L would like look like this:

Isn't the P/L Day wrong? Why isn't it ABC = -$250; XYZ = 0; Combined = -$250?

It said that at the end of the first day, the share price was $11, and your total portfolio value is 101k. If, on the second day one of the stocks drops, then you've lost value

**relative to the prior (first) day**. And if the other stock held steady, the P/L Day should be 0, no? So why is it still calculating P/L Day relative to the initial purchase price?
