Blame hyperbolic discounting.<\/p><\/div>\n<p>The market soars on hearing the good news. It soars because once again, after a brief hiatus in the wake of that scary Flash Crash of 2010, eighty percent of market trading is once again done by bots,\u00a0 and bots don&#8217;t get sarcasm yet.\u00a0 They only read the words they see online, take them at face value; they don&#8217;t understand that Merkel meant exactly the opposite of what she said.<\/p>\n<p>We, however, do. Finally, thanks to Trump, traders who inhabit meat have a fighting chance against those who inhabit silicon. Until bots learn about sarcasm and deception, at least.<\/p>\n<p>That window may be closing even as we speak. The machines are already picking up some of those nuances. Not the HFT bots with split-second memories; those are dumb fast algos, always will be.\u00a0 But the deeper AIs, the nets with layered interneurons; <em>they<\/em> seem to be catching on. Trump&#8217;s tweets are already showing less of an impact on the markets than they did after his Merkel Meeting.<\/p>\n<p>I asked my friend: are those tweets losing influence because the people writing the code said &#8220;Wow, Trump&#8217;s a fucking loon\u2014 we&#8217;d better go in and tweak those parameters&#8221;\u2014 or because the code itself is learning on its own?\u00a0 I mean, if I was a trading net, I&#8217;d use some Bayesian thing to constantly update the weight I attributed to any given source: the more often it paid off when compared to independent data, the more seriously I&#8217;d take it next time, and vice versa. Maybe the AIs are doing that?<\/p>\n<p>My friend didn&#8217;t know.<\/p>\n<p>I&#8217;m hoping one of you might.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Excerpts from dinnertime conversation with a retired investment banker: Angela Merkel emerges from a meeting with Donald Trump. &#8220;Yes,&#8221; she says in answer to a reporter&#8217;s question, &#8220;we had a provocative but productive discussion.&#8221; She rolls her eyes.
