It doesn't matter what i bought it at.

I sold at a much higher price- and bought it back at a lower price than that what i sold it for. What's so confusing about that?

You buy 100 widgets at $1 each
Said widgets increase to $6 each

You sell them for 600, knowing people will also sell, and the price will drop.

Said widgets drop down to 4.50.

You buy them back, and you now hold 133 widgets for the same $600.

I dunno about you, but I'd rather have 33% more for the same money.

Each their own though.
