The rapid spread of the highly contagious Delta variant of the coronavirus in many places across the globe including the United States dealt a huge blow to the Zacks Transportation - Airline industry. This is because after being battered by the pandemic-borne crisis last year, the airline operators were just finding their feet owing to improved air-travel demand (particularly for leisure). However, the rampant transmission of the highly infectious strain of COVID-19 is threatening to undo this uptick in air travel. Apart from the Delta-variant woe, steep fuel costs as a result of northbound oil prices are also limiting the airlines’ bottom-line growth. However, the focus on cargo revenues is a positive in this era of dwindling passenger revenues. Moreover, the recovery in air traffic in places like Latin America too offers a breather. This development bodes well for carriers like Azul AZUL, Copa Holdings CPA and Gol Linhas Aereas Inteligentes GOL. Tech IPOs With Massive Profit Potential In the past few years, many popular platforms and like Uber and Airbnb finally made their way to the public markets. But the biggest paydays came from lesser-known names. For example, electric carmaker X Peng shot up +299.4% in just 2 months. Think of it this way… If you had put $5,000 into XPEV at its IPO in September 2020, you could have cashed out with $19,970 in November. With record amounts of cash flooding into IPOs and a record-setting stock market, this year’s lineup could be even more lucrative.See Zacks Hottest Tech IPOs Now >>Want the latest recommendations from Zacks Investment Research?
