NEW YORK (TheStreet) -- Search-engine giant Google (GOOGL) - Get Report , known for its Orwellian marketing skills, as well as for a level of dominance in its field that even the Roman Empire would admire, has broken its stock price downtrend. Its shares had been losing ground since September, declining roughly 18% before rebounding off their 52-week low of $490.91 last month. Google has since regained some of those losses, up 9% from that low.

As of Monday, Google's class A shares closed at $535, up 1% year-to-date.

Google shaped a double-bottom formation in late December and early January, when shares tested and retested the $497-to-$500 range. Price action then turned upward, crossing over the 20-day and 50-day simple moving averages, signaling a bullish reversal. Then, Google reported positive fourth-quarter earnings on Jan. 29, causing price action to gap up on heavy volume. Shares then consolidated above the 50-day simple moving average for a couple of weeks.

There is a short-term trend that has been confirmed, as shares are creating higher highs and higher lows. Any trading over the 50-day simple moving average is a sign that it's worth negotiating an entry. On Monday, shares dipped to the 20-day simple moving average, and closed right on it, offering a better entry point. Look for a good entry point this week at anywhere between $525 and $542. A stop order could be set at $497: If the price trades below that range, the uptrend will be broken. A more conservative stop could be set at $512, as you could always enter a new position if the stock bounces back.

This week, traders will be testing Google's trend reversal. As shares dip toward the 50-day simple moving average, investors should take advantage of this buying opportunity.
