... Ahm. No. That's a percentage, not a specific tu amount.

For instance, if a stock goes up by 50%, the stock's previous value has half of itself added on to it for the new value. If it goes down by 50%, the new value is simply half of the previous value.

Although of course, these are all just estimations. For some reason the percentage shown is never quite accurate - which is probably why they sometimes appear to have gone down by 103%, despite that that should be impossible.

My best piece of advice concerning the percentages is to pay attention to all of them, rather than just one at a time. They're almost useless individually, but when you look at all the percentages, you can often see patterns. If most of the stocks dropped at the last reset, then it's usually safe to bet they'll rise at the next. The opposite is true as well.

It makes a good way to tell when to buy and when to sell.
