Actually I believe what investors want are higher stock prices, a company doesn't necessarily have to be profitable to achieve that. Take a look at SGEN, as an IMGN investor I've continued to believe it was a better investment, but SGEN just kept going up in spite of having few profitable quarters. What it does have is some approved drugs that it still owns a majority of.
A company that continues to grow it's pipeline and expand the labeling of its approved products can easily spend more than they're bringing in and continue having their stock price increase. Imagine what would happen if they stopped clinical development and just sold product, they'd become very profitable instantly, however they'd just have stabile sales rather than growing with each new product and label enhancement.
This business model means dilution rather routinely, shareholders are happy to authorize the additional shares as long as the share price just keeps rising. Look at companies like Tesla, it's one of the fastest growing in the world, but I think it's had few profitable quarters. Anyone think Elon Musk isn't a success in spite of not being profitable yet.
