Biohaven Ltd. BHVN shares ended the last trading session 7.6% higher at $13.18. The jump came on an impressive volume with a higher-than-average number of shares changing hands in the session. This compares to the stock's 91.8% loss over the past four weeks.The rise in share price is likely attributable to investors' optimism about the company's new direction, following the acquisition of its calcitonin gene-related peptide (CGRP) business by Pfizer. Post the acquisition, which was closed on Oct 3, Biohaven is advancing its non-CGRP pipeline compounds, which will focus on targeting neurological and neuropsychiatric diseases. Biohaven also has a cash balance of $257.8 million and currently carries no debt.This company is expected to post quarterly loss of $2.45 per share in its upcoming report, which represents a year-over-year change of +6.8%. Revenues are expected to be $246.61 million, up 81.7% from the year-ago quarter.Earnings and revenue growth expectations certainly give a good sense of the potential strength in a stock, but empirical research shows that trends in earnings estimate revisions are strongly correlated with near-term stock price movements.For Biohaven Pharmaceutical Holding Company Ltd., the consensus EPS estimate for the quarter has been revised 3.8% lower over the last 30 days to the current level. And a negative trend in earnings estimate revisions doesn't usually translate into price appreciation.
