  • SLV Undervalued Or Overvalued?  3 comments
    Jul 23, 2012 8:34 PM | about stocks: SLV

    The chart for iShares Silver Trust SLV is near a one year low. However, a low stock price does not always suggest a stock is "undervalued" or "overvalued".

    Different from a stock traders evaluations based on technicals or fundamentals, option traders compare relationships between historic and implied volatility to determine whether a stock is "overvalued" or "undervalued". There are different types of volatility, but options traders tend to focus on historical and implied volatilities IV. Historical volatility HV is the annualized standard deviation of past stock price movements. Traders use HV measures to frequently compare the charts of implied volatility to determine if options prices and stock prices are over or undervalued. Below is a one year chart of SLV 30 day HV average, IV index call and IV index put.

    As you can see, SLV is nearing an IV index mean one year low, implying at least front end (expiring July-August-September) put and call options are undervalued. For option traders and stock traders it can be an advantage to trade equities with low IV in a period of market uncertainty.

    For instance, options traders can tactically position a long strangle. For a trader trading the low IV for SLV he or she would purchase near-the-money front end calls and puts. Stock traders can also take advantage of a low IV for SLV by hedging their investment with undervalued put options, or if the investor is short, he or she can hedge with call options. Below is a comparison of option prices for SLV put and call option calendars expiring January 18, 2013 and September 21, 2012.

    I'll try to post some future article on a "how to" applying IV and HV to underlying stocks, ETFs, ETNs, options.
