‘Cortisol is likely to rise in a market crash and, by increasing risk aversion, to exaggerate the market’s downward movement.’
I listened last night to an interview with Dr John Coates, a former Wall Street trader and the lead author of research published in April by the Judge Business School in Cambridge, analysing the impact of hormone levels (testosterone and cortisol) on traders performance and their ability to make judgements.
Coates goes on to say in the interview:
‘Cortisol, if you’re exposed to it chronically at high levels for a long period of time, it can have a devastating effect on both the mind and the body. In terms of affecting traders decisions what it can do is affect the memories you recall. You tend to recall bad memories, negative precedents. You tend to see risk where maybe there is none. You become fearful, you feel anxiety. I think that decreases a trader’s appetite for risk. While testosterone is causing people to take too much risk cortisol is causing people to take too little risk in the crash.’
I had also earlier read Tim Prices excellent weekly commentary ‘Diamonds amongst rubble’ suggesting that the [orchestrated?] inducement of large amounts of fear in all of us was necessary to get the financial rescue packages that the banks were looking for.
So are we all now dithering in overdoses of Cortisol induced by fear?
Can we no longer make rational decisions?
How long does it take to wear off?
Has the ‘market’s downward movement’ already been exaggerated?
People react in different ways to fear. Maybe we should worry less about the fear and more about balancing fear with opportunity.

September 12th: Simon Hope, Savills (SVS, 205p) Executive Director with responsibility for Capital Markets, sells 62283 Savills shares at 295p, taking his holding to 87,547 shares and raising GBP 183,797.
September 16th: followthedirectors comments: ‘Savills – further to fall – Directors sell’
October 17th : ‘Savills Says Earnings Will Miss Analysts’ Estimates’ (Bloomberg article) : ‘this year’s pretax profit will miss analysts’ estimates because of the slump in transactions caused by the credit-market turmoil.’
I know that in these markets five weeks is a lifetime, but do you not think the board of Savills have had regular discussions about the risk to their profits and earnings in their weekly board meetings?
If you had followed Savills directors dealings and the followthedirectors commentary, then this news would be no surprise to you.
Find below the performance you might have achieved if you had followed our commentary (I list here the dates of my comments, and the share price performance between them):
November 8th (followthedirectors say ‘don’t buy’). Performance to March 10th SVS down 5%
March 10th (‘results wednesday, watch out’) Performance to August 4th, SVS down 35% absolute, or down 13% relative to the FTSE 250.
August 4th (‘time to buy?‘) to September 12th, SVS up 33% absolute, or 32% relative, but Hope didn’t announce his sale until yesterday, so use August 4th to September 15th, SVS up 23% absolute, or up 25% relative.
September 16th (‘further to fall’) to today October 17th, SVS down 23%, but up 5% relative to the FTSE 250.
I would suggest that the risk in Savills remains distinctly on the downside.

When I wrote my post of September 15th ‘Hargreaves Lansdown- more selling, signal strength now STRONG’, I was unaware of the reason for so many share sales.
The reason directors of Hargreaves Lansdown (HL. 182p) have been selling is that this is the anniversary of their listing (see Citywire article here), and the lock up for part of their shares falls away.
This in my mind justifies the share sales as the directors are probably diversifying their financial assets. Although you might question whether they would all rush for the exit if there was good news ahead!
As a result of this I believe these sales have a lower value to investors, and I am moving the Signal strength indicator from STRONG signal to WEAK signal.
