Oliver’s Insights – Corrections, gummy bears and grizzly bears in shares

Key points

• Shares have had a good rebound but could still fall further in the short term as risks remain high around monetary tightening and geopolitical tensions.
  
• However, a deep bear market is unlikely as US, global and Australian recessions are unlikely to be imminent.
   

Introduction

While shares have had a nice rebound from their January lows helped in part by some good earnings news – reversing around half of their 10% or so fall, concerns remain high around inflation, monetary tightening and the high risk of a Russian invasion of Ukraine. Our assessment remains that it’s too early to say we have seen the lows, but we remain of the view that January’s falls are not the start of major bear market.

The three bears – correction, gummy & grizzly

Very simply there are 3 types of significant share market falls:

• corrections with falls around 10% - of course these aren’t really bear markets, but some might feel they are!;
• “gummy” bear markets with falls around 20% meeting the technical definition many apply for a bear market but where a year after falling 20% the market is up (like 2018 & 2020 in the US and 2011, 2015-16 & 2020 for Australian shares); &
• “grizzly” bear markets where falls are a lot deeper and usually longer lived and where a year after the initial first 20% fall the market is still down (like in 1973-74, US and global shares through the tech wreck or the GFC).

I first saw the terms “gummy bear” and “grizzly bear” applied by stockbroker Credit Suisse several years ago and find them to be a good way to conceptualise bear markets. Grizzly bears maul investors but gummy bears eventually leave a nicer taste (like the lollies). As we pointed out a couple of weeks ago in “Share market falls – seven things for investors to keep in mind”, corrections are quite normal and healthy as they enable the sharemarket to let off steam and not get too overheated. Excluding the present episode, since 2011 there have been roughly seven corrections and three gummy bear markets (2011, 2015-16 and 2020) in Australian shares.

The next table shows bear markets in Australian shares since 1900. The first column shows bear markets, the second shows the duration of their falls and the third shows the size of the falls. The fourth shows the percentage change in share prices 12 months after the initial 20% decline. The fifth shows whether they are associated with a recession in the US and/or Australia. The final column shows the 1-year rebound from the low.

If a gummy bear market is defined by a 20% decline after which the market is higher 12 months later, whereas a grizzly bear market sees a continuing decline over the subsequent 12 months after the first 20% decline, then since 1900 there have been 13 gummy bears (highlighted in black). That leaves six grizzly bear markets (in red). Several points stand out:

• First, the gummy bear markets tend to be a bit shorter and usually see much smaller declines averaging 27% compared to 46% for the grizzly bear markets.
• Second, the average change over 12 months after the initial 20% fall is 15% for the gummy bear markets, but it’s a 23% decline for the grizzly bear markets.
• Third, the grizzly bear markets invariably go with recessions, whereas the gummy bear markets tend not to be. Five of the six grizzly bear markets saw a US and/or Australian recession whereas less than half of the gummy bears did.
• Fourth, after the low the share market rebounds sharply. This makes it hard to time, as by the time investors get back in the market is often above where they sold.

US share market falls are also much deeper and longer when there is a recession and, of course, moves in US shares have a significant influence on the Australian share market. The next table shows US share market falls greater than 10% since the 1970s. The first column shows the period of the fall, the second shows the decline in months, the third shows the percentage decline from top to bottom, the fourth shows whether the decline was associated with US recession or not and the fifth shows the gains in the share market one year after the low. Falls associated with recessions are highlighted in red.
