But Salamone has advice for those traders interested in possibly trying out the new innovation: look for the best value. For a buyer, it could be that the implied volatility on the new issues is higher than their larger 100-share counterparts. That means that that while the actual price may be lower than the full-sized version, the value may not be the same.

He likens it to different sizes of ketchup or hot sauce at the grocery, with the smaller bottle costing less, but the larger bottle being a better value since it costs less per ounce.

"In the best-case scenario, one would want to see the implied volatility on the standards and the minis to be the same," Salamone says. "And if they're not, that is something that should be considered before playing it. If the implied volatility on the standard is 35% and it's say, 40% on the mini, then they need to think long and hard about it before getting short-changed."

Ilyevsky offers other advice for new traders. First, make sure you have the correct ticker and check with your brokerage about how they will differentiate the full 100-share version from the mini-options. And second, keep it simple at the start like taking advantage of some of the more traditional covered call and buy-write strategies.

"Start out slow," Ilyevsky says. "If you have 20 shares of Apple, just try a covered call to start out with. But I would imagine that most of the people who will be able to take advantage of this are already fairly active in the market and will intuitively know what to do right away.

"This is a fantastic opportunity for everyone, especially the smaller investors and the brokerages, to grow the business. "
