You are already too late, everything jumped back. The key to making profit is to buy when it is red and when this is uncertain that it will recover. When it's already green you will make close to zero profit, if any. You must take risks, like all the time, to make profits.
Yes and those red day is gone and you didn't catch it. That would be the perfect timing for investors that want decent profit.
You can buy now but take the risks.
