Growth companies often have not yet achieved positive earnings. Instead growth advocates are top line driven. The idea being that top line propels bottom line. In other words, if you have revenue then earnings will come. Sales growth, revenue trends and market share reign supreme.
Growth stocks are often new companies in new industries exploring new markets.
With earnings absent, a new standard is required. Both growth and value investing are fundamentally mentally based. In contrast, some investors are technically oriented traders. Technical analysis is a bit like astrology in that its chart driven. However, instead of interpreting the position of the starts, technical analysts focus on movements in stocks' trading activity.
