In case you missed it, Google (GOOG:NASDAQ) reported fourth-quarter earnings today. And like all its other announcements, its numbers were staggering.

GOOG's revenues and earnings topped estimates -- and even exceeded some of the highest-level expectations.

For example, analysts expected the search giant to generate $2.19 billion.

Google reported revenues of $2.234 billion.

Analysts also expected Google to earn $2.91 per share. Some investors expected as much as $3 per share.

No problem, Google earned $3.29 per share. And so far, GOOG's history of blowing out earnings continues. But then came GOOG's cash flow.

Cash-flow estimates for Google were $1.38 billion, which represented a 62.8% margin.

But shockingly, Google reported cash flow of $1.384 billion, good for only a 62.1% margin (note sarcasm here).

So as it stands, GOOG “missed,” if you can even call it that, its cash-flow margins by seven-tenths of 1%. And because of that ever-so-slight miss, GOOG is trading over $11 lower today.

If that's how Wall Street is going to treat GOOG at these levels, then you can officially call it a “double-top” formation at the $512 level, which would mean that GOOG could trade lower -- and perhaps even filling the gap at $420.

That's a full $68 lower then current levels.

After all, if investors are done cheering GOOG's great numbers, then it's certainly due for a fall.
