Anticipation about Afrezza

In spite of expectations that MannKind Corporation (NASDAQ:MNKD)’s drug will receive FDA approval, some investors appear to be remaining cautious about the company. The drug maker’s market capitalization is now over $4 billion thanks to today’s share price increase—and MannKind doesn’t even have any revenue yet. In addition, Street Insider notes that money flow on MannKind is -$1.7 million, setting an uptick-to-downtick ratio of .92 times.

Nonetheless, the general consensus regarding sentiment for MannKind Corporation (NASDAQ:MNKD) is bullish, according to analytics from StockTwits. Some users of StockTwits say the concern about buying MannKind stock at its current price is whether or not the drug maker can market and sell Afrezza fast enough to justify its soaring valuation.

Buyout speculations for MannKind

Others say it isn’t the valuation that attracts them to MannKind because they believe approval for Afrezza will make the company an attractive acquisition target for a larger pharmaceutical company. Some big names that are being floated on the online community are Merck & Co., Inc. (NYSE:MRK).

This speculation actually makes some sense, as Merck management has already said they might consider looking for outside opportunities to grow, a.k.a., potential acquisitions. Indeed, the number of mergers and acquisitions that has been happening in the pharmaceutical industry late has been rapidly increasing.
