VIX Premium Ratio Finally Perks Up 5 comments

This week may be a turning point. None of the indicators below are quite at extremes, and I am keeping my S&P volatility bias at neutral since I would rather be a little late than very early. However, notice that volatility sellers have been “right” since at least mid-April, [5] a trend which is far more likely to reverse sharply than to flatten out. The S&P 500 looks overbought on a price basis, [4] especially since rallies are historically less likely to tarry in that two sigma channel. The futures complex continues to stay on the skeptical side versus plunging spot IV index levels.[7] And the VIX Premium Ratio [8] is finally perking up - the current reading of 1.07 is the highest since April 17, a day that was followed by a 15% jump in the VIX.
Besides the layout change, I’ve added three charts this week. The price and Bollinger Band charts for SPX [4] and GLD [9] replace the price and IV Index charts; it is helpful to know when an asset has risen or fallen two standard deviations from its 50-day mean. The implied volatility indexes for the S&P 500, gold, oil, and USD/EUR are displayed in [3]. In the coming weeks, I plan to add charts for oil and the dollar/euro similar to those already provided for gold.

1. Comment. Highlights items of note in the data below along with our short-term volatility bias and any trading theses. The Expected Daily Move table displays the de-annualized price and percentage change in each underlying asset as implied by its volatility index, withinone standard deviation.
2. Weekly Change.Tracks the weekly percentage change in the assets listed and in their implied volatility indexes.
3. Implied Volatility Indexes. A one year chart of the implied volatility indexes for the S&P 500, gold, oil, and USD/EUR. Indexes for the Nasdaq 100 and Russell 2000 are omitted because of their tight correlation with VIX.
4. S&P 500 Price and BollingerBands. Tracks daily closing prices in SPX with an overlay of one and two standard deviation 50-day bands.
5. S&P 500 Implied and Realized Volatility. Tracks the 21-, 60-, and 90-day realized (or “historical”) volatility of the index and the 21-day lagged CBOE Implied Volatility Index ("VIX"). Realized volatility is displayed as the annualized standard deviation of lognormal returns over the period specified, and may be thought of as a backward-looking measurement of price behavior. Implied volatility is the annualized standard deviation of returns implied by option prices, and may be thought of as a forward-looking measurement of expected price behavior.
6. S&P 500 Implied/Realized Volatility Ratio. Tracks the ratio of 21-day lagged implied volatility (IV) to 21-day realized volatility (RV). This ratio asks how well IV from one month ago predicted the RV over the next 21 trading days (roughly, 30 calendar days). When IV correctly anticipates RV over the period, the ratio will hover near 1; we regard the area near 0.9 –1.2 as normal, given the persistence of a volatility risk premium in equity market derivatives. A ratio less (greater) than 1 indicates that the price behavior of the underlying asset was more (less) volatile than anticipated.
7. Volatility Futures Term Structure. Tracks the Friday closing prices of the Volatility Futures complex (VIX, VXD, RVX) for the two weeks prior, along with the spot levels for reference.
8. VIX Premium Ratio. Tracks the ratio of rolling three-month (VXV) to one-month (VIX) implied volatility. Periods in which one-month readings persist at an extreme premium or discount to three-month levels have tended to coincide with major market moves.
9. Gold Price and BollingerBands. Tracks daily closing prices in GLD with an overlay of one and two standard deviation 50-day bands.
10. Gold Implied and Realized Volatility. Tracks the 21-, 60-, and 90-day realized (or “historical”) volatility of the ETFand the 21-day lagged CBOE Gold Volatility Index ("GVZ").
11. Gold Implied/Realized Volatility Ratio. See #6 above; given the novelty of the VIX-style gold volatility index (GVZ) and the characteristics of the underlying, we do not yet have a range we regard as normal.

Nice charts - always like to look at "nice" charts.
Implied volatility is a measure of expected volatility over the next month.
Realized volatility is a measure of realized volatility over the previous month.
So today's realized volatility value corresponds to the implied volatility one month ago. Therefore, you should lag the realized volatility and not implied.
