However, Uber looked like the better bet to two technical analysts, they told CNBC's "Trading Nation" on Monday.
Though she wasn't keen to add exposure to either "toppy" stock ahead of earnings, Katie Stockton of Fairlead Strategies said Uber's recent underperformance "positions it better" than its peer.
"The 200-day moving average for Uber is about 15%-16% below" its current trading price, said Stockton, her firm's founder and managing partner.
"In contrast, the 200-day moving average is about 24% below for Lyft. So, that creates some downside risk in the event that earnings disappoint," she said.
Uber's more of a long-term buy than an earnings trade, however, Ari Wald, head of technical analysis at Oppenheimer, said in the same "Trading Nation" interview.
