Relative Strength Index - RSI
Relative Strength Index - RSI
Image 1 A technical analysis indicator that compares the days that a stock finishes up against when it finishes lower.

The RSI ranges from 0 to 100, but a stock is considered overbought if it reaches the 70 level and you should consider selling. When the market is a true bull market then 80 might be a better level since stocks often trade at higher valuations. Likewise if the RSI approaches 30 it is a strong buying indicator and 20 in a strong bear market.

Image 2 The RSI is a big tool in momentum trading. The RSI can help you make so serious money, but be forwarned that it isn't a decision maker. Big surges and drops in stocks will effect the RSI, but it could simply be just a false buy or sell. The RSI is best used as a valuable compliment to your other stock picking tools.
