For a market to bottom, enough people have to become confident enough to hold stocks during a prolonged new rise. Most bottoms have to have a successful retest of the lows to help build that confidence. A lot of people missed getting out before this recent carnage. They will likely sell as the market bounces and we may then get more of a decline. In my lifetime bear markets have lasted about 10 months. We are likely in the early stages of this decline. But no one knows for sure. Bottoms are declared well after they are in place.
