Price is beneath the bottom band set on an 80 DMA, so stretched to the downside today. Probable bounce to the upside soon.
An Arc is formed when price virtually goes almost straight up and can be better seen on a weekly or monthly chart. This pattern makes it worth checking a security on longer time frames if you plan to buy stocks at a high price. Folks are super bullish inside an Arc. Most fall between 50 and 79% of the rise up, but they can fall less or more than this amount. Price is volatile on the way down as a rule.
