Trend-following is essentially a “tried and true’ approach to investing. But overbought/oversold (i.e., attempting to buy low/sell high) – that’s where the “excitement” is. Of course, when it comes to trading and investing, “excitement” can be highly overrated. Nevertheless, in this piece I want to talk about a relatively obscure indicator that may be useful in identifying vastly oversold situations.
The VixRSI14 Indicator
Part of the reason this indicator is obscure is because I think I “invented” it – but only by mashing together an indicator from Larry Williams and an indicator from Welles Wilder. The first part is the standard Welles Wilder 14-day Relative Strength Index, more commonly referred to as “RSI”.
The 2nd part of VixRSI14 is an indicator created by famed trader Larry Williams which he dubbed “VixFix”. This indicator is an effort to create a “Vix Index-like” indicator for any security.
AIQ TradingExpert code for these indicators appears at the end of the article.
A Few Notes
*For the record, VixRSI14 is calculated by taking a 3-day exponential average of VixFix and dividing that by a 3-day exponential average of RSI14 (are we having fun yet?). Please see code at the end of the article.
*I prefer to use VixRSI14 using weekly data rather than daily data
*(Unfortunately) There are no “magic numbers” that indicate that a completely risk-free, you can’t lose, just buy now and watch the money roll in” buying opportunity is at hand (Disclaimer: If there was, I would probably just keep it to myself and not bother writing the article – sorry, it’s just my nature). That being said, a decent “rule of thumb” is to look for a reading above 3.5 followed by a downside reversal.

With those thoughts in mind, Figure 1 displays a weekly chart of Wynn Resorts (WYNN) with the two indicators plotted separately below the bar chart.

Note that as price declines, VixFix tends to rise and RSI14 tends to fall. VIXRSI14 essentially identifies “extremes” in the difference between these two. Figure 2 displays WYNN with VixRSI14 plotted below the bar chart.

Summary
As always, I merely present “ideas” here at JOTM. So, do not assume from the charts above that you have found the “keys to the kingdom”. But if used in conjunction with other confirming indicators – and remembering to employ some sort of risk control for those instances when a stock price decline fails to arrest itself even after VixRSI4 peaks above 3.5 – VixRSI14 may hold some value.
