Buddy, you're not even remotely in my league when it comes to business acumen. These nonsensical questions that you asked are out of a 1st year, undergrad, business school course. This F stock rating nonsense that you keep trying to push is a 12-month projection vs the equities markets/stock exchanges (markets where you can buy and sell shares of stock). That's it, nothing more. The stock could take off or continue on a slow growth trajectory. It does not mean that the company is in danger of bankruptcy or insolvency. If that is what you are looking for, then calculate a quick ratio or acid test. However, make sure that you compare the ratio to similar size companies in a similar industry, or it was for naught.
Are you keeping up, stupid? Now, let's look at why the Esperion stock price increased so dramatically. You see the stock price begin to increase around January 27, 2020. Why? The investors were anticipating drug approvals for Esperion. The smart money will jump in (here is a concept that you should understand) and buy low. The drug gets approved on the 20th, and the money begins to sell (another concept that you should understand). The continued decline was more of the effects of a bear market. Get on Google and Yahoo Finance. Look up NPV, IRR, WACC, and Discount Rates. It will help you understand how companies invest. As for the scripts. You, really, are that dense. There's a lack of promotion, moron.
Look, I have an undergrad in Finance with a minor in Mathematics and two Master's degrees from a top 20 business school. You can try this inane and childish game, if you'd like, but you're not in my zip code when it comes to this. Grow up. Your bitterness is pathetic. You're the jilted bride/groom. Move on. I promise, you'll find someone to love you.
Disclosure: I don't work for Esperion. I, just, find you pathetic.
