Despite one analyst's upbeat view for the stock, he's uncertain about Fastly's near-term business performance. Revenue growth may be accelerating, but Fastly's bottom line is moving in the wrong direction. Investors may want to wait before the edge-computing company demonstrates better operating leverage before they invest. Fastly is still facing many challenges. Edge computing specialist Fastly (FSLY 2.99%) is set to report results for its fourth quarter of 2022 after market close on Wednesday.While the company is making some important progress, it might be wise for investors to wait for management to demonstrate meaningful progress toward profitability first. Fastly's loss per share widened in Q3, coming in at a loss of $0.52. This compares to a loss of $0.48 in the year-ago period. The BoA analyst bullish calls is premature. The recent spike in Fastly stock price is an over reaction and might be due for a sharp correction.
