The WhaleWisdom Insider Sell vs Buy Ratio was this bullish twice before: Nov. 2008 and March 2009. Have we seen the Coronavirus bear market bottom?


The WhaleWisdom Weekly Sell vs Buy Ratio has shown historically low — bullish — readings for two weeks in a row. For the week ending March 16, 2020, the indicator was 0.27 — the most bullish weekly reading since Nov. 24, 2008’s weekly reading of 0.25. That insider sell vs buy ratio during the financial crisis was the lowest recorded over the last 12 years.

The Sell vs Buy Ratio for last week was 0.42, also very bullish. Only twice before has the indicator shown back-to-back readings below 0.50 — late Nov. 2008 and early March of 2009. Was it up, up and away after those two bullish weekly readings? Not exactly.

The ratio reflects the number of officers and directors buying stock on the open market vs those selling. As I’ve written previously, when key insiders are broadly buying stock in their own companies, and selling very little, history shows that the stock market is approaching a bottom. However, the bottoming process is likely to be a wild ride and may include new bear market lows.

The WhaleWisdom Insider Buy vs Sell Ratio was below 0.50 for the last 2 weeks ending March 20, 2020. A level of bullishness only reached twice before — during 2008-09.

After the 0.24 Insider Ratio for the week ending 11-24-08, there were more 5% moves up and down in the weeks going forward. The market worked higher for about 6 weeks. From the low on Nov. 21, 2008 to the rally high on Jan. 5 of 2009, SPY gained 27%. From there, selling reasserted itself, and SPY declined 29% before making new lows, bottoming on March 6, 2009. Significantly, VIX readings during the breakdown were much lower than in Nov.

The Insider Sell vs Buy Ratio reading of 0.41 for the week ending March 9, 2009, coincided closely with the low for the 2008-09 bear market. As the market climbed into the following week, another bullish reading of 0.44 indicated that officers and directors continued to find extensive bargains in their own shares.

If the Coronavirus bear market plays out like 2008-09, we’ll see more head-spinning volatility in the weeks ahead.

Now of course there is no guarantee that the stock market or insider buying behavior will mirror 2008-09. While the Coronavirus bear market has similarities to the Financial Crisis period, the pandemic is an external shock unlike anything we’ve witnessed in our lifetimes.

Nonetheless, if history is indeed a guide, we can expect elevated volatility in the weeks to come. This means chasing rallies will be a mistake. Long term investors should accumulate on weakness — buy on the big down days. The bear market bottom will be a process over weeks and possibly months. In the coming days there will scary headlines interspersed with periods of hope that the worst is over. The stock market discounts the future. At some point the worst will, in fact, be behind us. And a new period of prosperity, along with a new bull market, will begin.

Before then, however, a break below the reaction low of March 23, 2020 remains a high probability. This is what happened 11 years ago. The market put in a bottom in late Nov. 2008, accompanied by 80+ VIX readings, and extreme insider buying. The market then rallied for five weeks, before turning south again, breaking the previous low. That was the final capitulation — many investors couldn’t stand the pain and threw in the towel. (Insiders, on the other hand were buying the downdraft. Many made millions on stocks bought during this period.) If the market makes new bear market lows with less extreme VIX readings, accompanied by strong insider buying, then a bottom for the Coronavirus bear market would likely be in.
