Earnings WhispersOur proven model does not conclusively show that Teladoc is likely to beat on earnings this quarter. This is because a stock needs to have both a positive Earnings ESP and a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold) for this to happen. That is not the case here as you will see below.Zacks ESP: Teladoc has an Earnings ESP of 0.00%. This is because both the Most Accurate estimate and the Zacks Consensus Estimate stand at a loss of 38 cents.Zacks Rank: Teladoc carries a Zacks Rank #3, which increases the predictive power of ESP. However, an ESP of 0.00% makes surprise prediction difficult.We caution against Sell-rated stocks (Zacks Rank #4 or 5) going into the earnings announcement, especially when the company is seeing negative estimate revisions.
