Ya'll are talking past each other. Since I made the comment, I will define my terms more precisely. In 2-3 years someone who consistently invests a fixed portion of their earnings/assets into a weighted vehicle/basket will be enjoying an appreciating net worth. I'm not claiming to be able to call the bottom, but I'm also not measuring "recovering" as peak-to-peak. Peak to peak would be past-tense "recovered".
