An Introduction To Weekly Options///
In 1973, the Chicago Board Options Exchange (CBOE) introduced the standard call options that we know today. In 1977, the put option was introduced.
In 2005, 32 years after introducing the call option, the CBOE began a pilot program with "weeklys" options. Investor interest in the weeklys has surged since 2009
Weekly Option Advantages for sellers..
For premium sellers who like to take advantage of the rapidly accelerating time-decay curve in an option's final week of its life, the weeklys are a bonanza. Now you can get paid 52 times per year instead of 12.
The Short-Term Advantage for buyers...
In addition, during three out of four weeks, the weeklys offer something you can't accomplish with the monthlys: The ability to make a very short-term bet on a particular news item or anticipated sudden price movement.
Let's imagine it's the first week of the month and you expect XYZ stock to move because their earnings report is due out this week. While it would be possible to buy or sell the XYZ monthlies to capitalize on your theory, you would be risking three weeks of premium in the event that you're wrong and XYZ moves against you. With the weeklys, you only have to risk one week's worth of premium. This will potentially save you money if you are wrong, or give you a nice return if you are correct.
