Shares of Peloton Interactive Inc. /zigman2/quotes/208035743/composite PTON +0.36% ran up 5.4% into record territory in morning trading Wednesday, after BofA Securities analyst Justin Post became more bullish on the fitness-equipment company, citing data suggesting demand continues to outstrip supply. Post reiterated his buy rating on the stock, while raising his price target by 17%, to $175 from $150. Post said his research indicates that visits to Peloton's site in the fiscal second quarter, which ended December, rose 167% from a year ago, a deceleration from 289% growth in the first quarter, "but well above competition." He said Peloton-related posts during the quarter on Facebook Inc.'s /zigman2/quotes/205064656/composite FB +2.58% Instagram are up 71%a, and are up 92% on Twitter /zigman2/quotes/203180645/composite TWTR +0.30% , "suggesting new user engagement remains high." He said while delivery times remain long, data suggests that order backlog should help support "strong" third quarter results. "While valuation is a risk, we remain constructive on the stock ahead of the full U.S. lower-priced tread launch, likely in March (potential catalyst)," Post wrote in a note to clients. The stock, which was trading above its Dec. 23 record close of $162.76, has rallied 25.5% over the past three months while the S&P 500 /zigman2/quotes/210599714/realtime SPX +1.95% has gained 8.5%.
