>>You're not the first person to have considered that the company might be successful and grow exponentially in the future -- that's already priced in to the stock!
This is actually a flawed view, because it assumes perfect information by all market participants. George Soros goes into quite a bit of detail in the second part of his General Theory of Reflexivity. You should read it.

Relevant excerpt:
"Let me state the two cardinal principles of my conceptual framework as it applies to the financial markets. First, market prices always distort the underlying fundamentals. The degree of distortion may range from the negligible to the significant. This is in direct contradiction to the efficient market hypothesis, which maintains that market prices accurately reflect all the available information.
Second, instead of playing a purely passive role in reflecting an underlying reality, financial markets also have an active role: they can affect the so-called fundamentals they are supposed to reflect. That is the point that behavioral economics is missing. It focuses only on one half of a reflexive process: the mispricing of financial assets; it does not concern itself with the impact of the mispricing on the so-called fundamentals.
There are various feedback mechanisms at work which may validate the mispricing of financial assets, at least for a while. This may give the impression that markets are often right, but the mechanism at work is very different from the one proposed by the prevailing paradigm. I claim that financial markets have ways of altering the fundamentals and that may bring about a closer correspondence between market prices and the underlying fundamentals. Contrast that with the efficient market hypothesis, which claims that markets always accurately reflect reality and automatically tend towards equilibrium. There are various pathways by which the mispricing of financial assets can affect the so-called fundamentals. The most widely travelled are those which involve the use of leverage—both debt and equity leveraging. These pathways deserve a lot more research."
