  • On a Prescriptive Model of Market Participant Behavior: Part 1

    In a recent article in the Seattle Times, Teri Cettina interviewed Dan Ariely about his new book entitled Predictably Irrational. Airely is a behavioral economist at MIT and Duke who has done wonderful research which helps to describe the ways in which people behave irrationally especially where money is involved. I love this type…

  • The Collective Market Participant Basket Case

    The simple truth is that measuring human emotion is extremely difficult. Expert researchers have been working at it since before the phrenologists felt the bumps on one’s head to divine personality. Its so difficult to do because emotions are super complex, intertwined dynamically with other modes of experience and remote to direct observation. So…

  • Centralizing Accountability

    I had a great breakfast this morning with Lindzon and Mick from Research Edge. Mick brought up the idea of centralizing accountability which I loved and which dovetails nicely with my piece on StockTwits and transparency.

  • Loss Aversion, Evolution and Risk Complacency

    Since the end of World War II, the U.S. has arguably experienced the greatest era of increasing prosperity in the history of nations.

That is they espoused a view of human nature as being mostly at the whims of forces beyond people’s control whether these forces were internal (needs, desires and conflicts) or external (war. political, socio-economic). Some of the more recent dynamic models have run counter to a deterministic view. One…

  • Fostering Transparency on StockTwits

    One of the toughest things for traders to do is realize losses. I have written about it here already. You also find that this holds in terms of what market participants are willing to fess up to in public. We see this with traders (and gamblers coming back from Vegas) all the time and…

  • Twitter and the Relational Field

    When people interact, very little attention is paid to the spaces between them, the field upon which they are interacting. Nevertheless, this space is an incredibly important part of the interaction. The energy behind the correspondence, the relationship of the participants, the implicit rules of the setting, the physical surroundings… I call the space…

  • The 'As If'

    Much continues as if half of the worlds wealth has not been destroyed over the past year. Families living at the margin are still booking trips to Disney. Pfizer is still copping Elvis to sell Viagra. The nouveau continues to trade in beamers for beamers. Don’t get me wrong the shift towards a more…
