You Just Need to understand Being 'Down 10% of 14,000 is 1,400. Means it's down to 12,600.

Up 10% from 12,600 is +1,260. Means it's at 13,860.

So still down by 140. Not a huge difference on initial inspection. Massive if you have all your life savings tied up in the market.

Note: these numbers are made up, but the math is correct. You can find me behind Wendy's if you feel some type of way about it. We'll either duck or fight, but either way, I'll be naked.
