Investors in once-little-known small-cap Adept Technology   had a riveting 2013, with shares up more than 400%. Those kinds of monster gains are nothing to laugh at, and leave investors with several questions: What caused this incredible rally, and is the party over yet?

Before buying or selling any stock, it can be very helpful to analyze why the stock has moved in order to evaluate what the stock market's expectations are for that particular company. When an investor has a good idea of what the market expects out of a company, then she can better evaluate if an investment is warranted. For Adept Technology's share price, the 400% change can be evaluated by looking at revenue and the price-to-sales ratio.

Which brings us to the two factors that can cause a price to increase. A stock price is equal to how the company is doing (sales) multiplied by how the market feels about the company's future prospects, which is expressed by the P/S multiple.
