There's no specific formula to deciding whether a stock has hit a target price. That said, you can ask yourself whether a stock's price is reasonable based on whether its market capitilzation is justified by its balance sheet and its level of growth. If you see cash flow from OA growing that is a great sign that the business is taking in cash from customers and able to invest in PPE or R&D. I really like seeing strong companies. I tend to love stocks with a PE ratio of between 8 and 16 or that have a PE that is less than 1.75x its growth rate.

In terms of technical analysis, I look at a stock's volatility history and try to buy at a satisfying price; a price that is near the bottom. If I'm shorting a stock against another stock or shorting an index, I'm less concerned about price than if I hold a long position in the stock.
