Investors of soft drink stocks have ample reason to be optimistic with leading companies like PepsiCo, Inc. PEP and The Coca-Cola Company KO delivering solid Q1 results. Despite declining demand for their sugary sodas, currency headwinds and slowdown in key emerging markets, earnings of these soft drink behemoths beat the Zacks Consensus Estimate, thereby bringing the sector in the limelight. Notably, Coca-Cola also beat sales expectations, while Pepsi’s top line narrowly missed the same.Higher sales of the so-called “healthy” non-carbonated drinks, improved performance in the North America segments, pricing gains, lower costs of key raw materials, cost reductions and productivity gains and overall better execution helped these companies deliver impressive results in the reported quarter.However, despite strong Q1 results, both Pepsi and Coca-Cola retained their previously issued guidance for 2016 due to a volatile macro outlook.This week, three other soft drinks companies, Coca-Cola Enterprises Inc. CCE, Dr Pepper Snapple Group, Inc. DPS and Fomento Económico Mexicano, S.A.B de C.V FMX are set to report their quarterly results.
