Nike had a drop of 3.2% and then gained .4% and people are making the claim that Nike is still doing good and it isn't a big deal. EVEN IF NIKE GAINED 3.2% back the next day IT'S STILL A NET NEGATIVE!!
Let me explain.
You own a company that is worth $1.00
And it drops 10% that means it lost 10 cents and is only worth $.90 now. So let's just say that the next day it GAINED back 10% that means that it's still below the previous stock value and only gained $0.09 that day, so now it still sits at $0.99
Hope that helps, when people talk about stocks and the DOW.
