**I'm posting an example to get my confusion resolved. Actual stocks do not matter.**
[24 analysts evaluated MRVL and gave it a low of $80 and high of $156](https://www.zacks.com/stock/research/mrvl/price-target-stock-forecast). Stock is \~$80 so no downside, 47% upside with average price and 94% upside with high price as per their evaluation.
[18 analysts evaluated TTD and gave it a low of $34 and high of $80](https://www.zacks.com/stock/research/ttd/price-target-stock-forecast). Stock is \~$34 so no downside, 67% upside with average price and 170% upside with high price as per their evaluation.
**My questions**:
1. despite TTD offering higher return in each case, why is the zacks rating for TTD (2.15) is lower than that of MRVL (1.62). Note lower rating means stronger buy.
2. why 3 analysts have marked TTD as "sell" when based on their own analysis there is no downside
