Sweetgreen (SG) shares have wilted thus far in 2025. TD Cowen downgraded the fast-casual salad chain to a hold from buy, cutting its price target to $15 from $25. Rachel Dashiell looks at the 90-day chart and says a break above $15 would give the downward trend a level of needed support. On a 1-year chart, Rachel says the 50-day moving average has been acting as an upside resistance level throughout the stock's move lower.
