A well-known technical indicator has just delivered a bearish signal for the S&P 500 index, which has previously been accurate in predicting market downturns.

On Friday, June 2, the S&P 500 index, represented by the SPDR S&P 500 ETF Trust (NYSE:SPY), broke through the 4,250 level, surpassing its 50-day moving average by more than two standard deviations.

This technical indicator, developed by John Bollinger and know as Bollinger Bands, is commonly used by traders to identify overbought and oversold conditions, potential price breakouts and trend reversals. 

When prices reach the upper Bollinger band, located two standard deviations away from the moving average, it indicates a sell signal, whereas touching the lower band signifies a buy signal.
