ALRN options questions
How do I buy ALRN options?
You need a brokerage account with options trading enabled. Find ALRN at your broker, choose a call or a put, a strike and an expiration, and place the order. Options carry substantial risk: one can expire worthless and lose all that was paid for it.
What is the difference between ALRN calls and puts?
A call gives the right to buy ALRN shares at the strike price and gains when the stock rises. A put gives the right to sell them at the strike price and gains when the stock falls.
How do I choose a ALRN expiration?
A shorter expiration costs less and reacts faster, and loses its time value sooner. A longer one costs more and gives the trade more time.
What is the implied volatility of ALRN options?
It differs by strike and expiration, so open the ALRN chain to read it for each contract. Higher implied volatility means the market expects larger moves, and the option costs more. It often rises before earnings.
What do in the money and out of the money mean?
An in the money option has intrinsic value: a call with a strike below the stock price, or a put with a strike above it. An out of the money option has none and costs less. An at the money option has a strike near the stock price.
