Down 30.6% in 4 Weeks, Here's Why You Should You Buy the Dip in Theravance Bio (TBPH)

(TBPH) has been on a downward spiral lately with significant selling pressure. After declining 30.6% over the past four weeks, the stock looks well positioned for a trend reversal as it is now in oversold territory and there is strong agreement among Wall Street analysts that the company will report better earnings than they predicted earlier.

We use Relative Strength Index (RSI), one of the most commonly used technical indicators, for spotting whether a stock is oversold. This is a momentum oscillator that measures the speed and change of price movements.

RSI oscillates between zero and 100. Usually, a stock is considered oversold when its RSI reading falls below 30.

Technically, every stock oscillates between being overbought and oversold irrespective of the quality of their fundamentals. And the beauty of RSI is that it helps you quickly and easily check if a stock's price is reaching a point of reversal.

So, by this measure, if a stock has gotten too far below its fair value just because of unwarranted selling pressure, investors may start looking for entry opportunities in the stock for benefiting from the inevitable rebound.

However, like every investing tool, RSI has its limitations, and should not be used alone for making an investment decision.

Here's Why TBPH Could Experience a Turnaround
