How did your father get into options? Options are crazy dangerous, especially for the novice investor.
I don't know anything about HEAR but we are familiar with tmus. My wife and I took a strong look at TMobile starting about a year ago. Disclaimer: anything below is my opinion and while my average is very good I am not always right.
Novice investors tend to take positions that they feel are 'logical' but investing at times requires a deep dive where the novice doesn't know where to look and may be counter intuitive.
TMobile is a company that is growing at a good rate for.the last three or four years but is not in a position to really threaten the big two providers, but they can, and have pushed the market for awhile. But in order to become a real force they need to grow a few tens of millions of users and this provides them with the economy of volume which they don't have now.
The obvious source of those users is Sprint who is in dire straits no matter how you look at it. So, tmo has offered to buy (merge) with Sprint. The obvious upside is millions of users to put tmo almost on a par with ATT and Verizon.
But here's the problem. Sprint comes with a massive amount of baggage, including no cash and billions of dollars in debt, all of which TMobile will have to assume. This is a 100 percent stock based buyout with Sprint stockholders getting 1 share of TMO stock for 10 shares of Sprint. Tmo is currently about 73 dollars to Sprints 6 dollars and change which means that Sprint stockholders will get about 19 percent gain (At today's price) just for having TMO buy them out. TMobile shareholders will see their stock heavily diluted because all those millions of shares will have to be issued to exchange for Sprint stock.
There's a lot more involved but this post is already very long. What it comes down to is that we decided against buying into tmus.
One example of our best buys was Dominoes Pizza. We bought it about three or four years ago at 52 dollars a share and right now it is sitting at 279 dollars. By the way, we don't buy Dominoes Pizza because we hate it. When it comes to investing there is no fanboism involved. One of our larger investments a few years ago was Apple and we don't own Apple products, it was purely a business decision, we got in rode the stock for a couple of years, then shorted and got out with a healthy profit.
My father-in-law knows less than I do about stock trading and he bought options of Goodyear. I tried to persuade him not to, he didn't listen, he lost.
Right now I'm watching HEAR and tmus, added some money to my account, just in case.
