In this newsletter, over the years we have presented many methods for protecting a portfolio of stocks. Some are “ancient,” such as buying S&P 500 Index ($SPX) puts and some are “new,” such as buying $VIX calls.

As such, the topic of protecting a portfolio with derivatives has once again risen to the forefront. With that in mind, I wrote The Striking Price column in Barron’s this week, on this topic.
