SUMMARY

All three indices finished the last week almost unchanged. They tried to continue their short-term uptrends started from the strong support levels reached in the beginning of February and April but this attempt has been interrupted in the last half of the week. Overall, they remain in the middle of the range formed in recent months.

Implied Volatility stays slightly elevated, RSI(14) is hovering around 50 mark showing neither oversold nor overbought condition.

No substantial changes in options mispricing occurred since the last Snapshot (April, 16): call options are priced fairly except for QQQ, puts are mostly overpriced as usual.

Mispricing summary for the options with 2-5 weeks to expiration:

  Puts  Calls
OTM ATM ATM OTM
SPY Overpriced Fairly priced Fairly priced Fairly priced
QQQ Overpriced substantially Overpriced substantially Underpriced substantially Underpriced
IWM Overpriced substantially  Overpriced Fairly priced Fairly priced

 

Market regime Filtering

To make our estimation more reliable, we filter the historical data and select from the past only those dates when the market resembled the current condition (read more here). We use three filters:

  • Long-term macroeconomic regime. We filter out the recessionary environment (or looming recession) with The Conference Board Leading Economic Index® (LEI) and select all dates when its 6-month rate-of-change was above -2%.
  • Volatility regime. We use VIX, VXN, and RVX indices as volatility filters for SPY, QQQ, and IWM respectively.
  • Short-term swing regime. We use Relative Strength Index (RSI) with 14-days interval - RSI(14)

We apply auto filtering for Volatility index and RSI selecting 300 days in history with the shortest Euclidean distance to their current values.

For each underlying, we select expirations on a range of 2-5 weeks. We present mispricing charts for each expiration and basic PL metrics for the best one-leg strategy  (buying or selling put or call) measured by the Expected profit (annualized).
