The analysis focuses on a linear regression chart for the US500. The strategy suggests selling above white lines and buying below them, based on observed patterns. Historical data from July shows a 3.49% drop after touching the upper white line, while August had a 2.4% decline. The current price is around 6615. Based on past patterns, a move back to the lower white line is anticipated, which is around 6440, representing a potential 2% decrease. If the price goes higher than 6620 the analysis should be invalidated.
