It’s certainly been a volatile time for markets. A rough August ended with a bounce on Wall Street last week, although stocks finished Tuesday in the red . Global stocks, too, were bumpy last month: The MSCI World index fell in the middle of the month before paring some losses toward the end. The relative strength index (RSI), which measures the magnitude and speed of price moves, can be used by investors to determine if shares are overbought or oversold. A stock with a 14-day RSI below 30 is considered oversold — implying that it could be a buying opportunity. Meanwhile, stocks with a 14-day RSI higher than 70 are likely overbought — and may be due for a pullback. CNBC Pro screened the MSCI World index for major global stocks that are among the most overbought and oversold, based on their 14-day RSI.
