How MONA’s David Walsh shocked our top stock pickers

There’s something magnetic about David Walsh, the professional gambler and owner of the iconic Museum of Old & New Art, who stole the show at the Sohn Hearts & Minds Conference in Hobart.

Anyone who has visited MONA (which hosted Thursday night’s pre-conference welcome) knows that the mercurial and mischievous Walsh loves to provoke a reaction. And he was quite happy to pour a bucket of cold water on the stock pickers, investment bankers and business people who would justifiably consider themselves the cream of Australia’s financial sector.

Walsh’s message to the 600-strong audience at the seventh annual Sohn conference? You’ve probably just been lucky.

Over the course of a fascinating 35-minute conversation with Andrew Denton – which was unquestionably the thought-provoking moment of the event – Walsh recounted the fascinating story of MONA’s establishment with what he considers the ill-gotten gains of his gambling career.

“All I do is redistribute money, and there’s no sense of accomplishment in it,” Walsh archly told the room full of money managers, sipping from a foaming Campari.

But it was Walsh’s career as a gambler that most fascinated the room full of professional risk-takers.

He explained how he dropped out of studying maths at university in Hobart and fell in with what he described as a bad, but fun crowd.

“They wanted me because I could do sums. And I wanted them because they could talk to girls.”

This enterprise, which is led by Rich Lister and Walsh’s great friend, Zeljko Ranogajec, started counting cards while playing blackjack at the Hobart casino and eventually took its act on the road. Walsh told the audience how he and his crew loved to visit Las Vegas for what was called the “Gorilla Big Play” on the nights when big boxing matches would be held, stationing card counters across the floor of a casino to take advantage of the increase in bet limits.

Walsh revealed that the syndicate, which Ranogajec still leads, bets about $10 billion a year across horse racing, sports betting and even lotteries. One of their biggest wins was a $63 million haul from a big horse race run in Tokyo on Christmas Eve, but Walsh said the crew won even more about six months ago betting on a German lottery that had jackpotted several times. The syndicate bought $11 million worth of tickets.

He only found out about the Tokyo win a week after the race was run.

“If you have to worry about whether your bets are winning, your bets are not going to win if you haven’t already got the system resolved to the point where it’s real.”

What makes Walsh so engaging is his ability to be brutally honest about his own strengths and weaknesses – not because of some sense of modesty, but because of logic and maths.

For example, becoming a professional gambler as a young man was silly, given he knew that the world was full of failed professional gamblers.

Walsh joked that he should have ended up in the street or, even worse, in the audience of the Sohn conference.

“If you assess it with the information that was available to me at the time, it was literally the worst decision I’ve ever made. It turned out well.”

This was down to luck, Walsh said. When the syndicate started betting bigger amounts and playing a wider range of games, Walsh went back and checked the maths of the systems it was using. What he found was that the syndicate’s edge over the house was not nearly as strong as they thought it was, and there was an 80 per cent to 90 per cent chance that the whole enterprise would be bankrupted because it was betting too much. So while Walsh thought he had a system that could beat the market, it turned out he was mainly lucky.

“That means nine out of every 10 people with a similar set of skills than me go broke,” Walsh said.

The lesson equally applies to investors, Walsh argued – even the top ones assembled at the Sohn conference.

“Finding a system that works and is stable and works for a long time is extremely difficult. If you’ve had a system that works for 20 years, it’s not as a result of skill. You acquire the system that worked by luck, then once it worked, it might keep working,” Walsh explained.

“The cohort here is probably a cohort who were mostly successful. But there is another cohort [that] would fill a stadium of people, that had similarly realised appropriate strategies, that either overbet them or simply chose strategies that didn’t work in the long run or failed to maintain those strategies. But there’s no difference in the level of skill of those that failed and those that succeeded.”

This was a challenging message for the rapt audience of money managers to hear. The idea that experience, skills and a system can deliver solid returns over time is central to everything professional investors do.

But Walsh’s underlying message was that hubris is a dangerous thing – your “edge” over the market may well be an illusion.

Walsh said he was currently pouring resources and energy into finding ways to protect the income of his syndicate from artificial intelligence. He’s some way off, but believes having data sets with unique observations that are not widely available could provide a way to tilt markets to the syndicate’s benefits.

But don’t expect to see him playing in financial markets. Walsh said 40 years studying equity markets had suggested that while they do rise over time in a random way, the other side of the equation worried him.

“What is not clear to me is whether the variance, the amount of risk, isn’t also going up. If it is, and if that variance is expanding faster than the growth of the market, then one day it will all turn to shit.”

Using artificial intelligence to predict flash crashes in markets, and trading the other side of those events, might be one way to use algorithmic trading in financial markets.

Walsh has plenty of incentive to protect his gambling income – he revealed MONA’s annual losses had blown out to $25 million.

And while the museum has been a boon for Tasmanian tourism, Walsh warned his Sohn hosts that there can be side-effects to philanthropy. The explosion of tourism numbers had led to an explosion in the number of Hobart properties on Airbnb.

“I created a homelessness problem, or I co-created it. It’s really hard to do good without side-effects.”

It’s not the worst problem to have, of course. The Sohn event, the brainchild of a group that includes Barrenjoey founders Matthew Grounds and Guy Fowler, veteran investor Gary Weiss and counts key supporters including Premier Investments’ Solomon Lew, Wilson Asset Management’s Geoff Wilson, Chris Cuffe and UBS veteran Michael Walsh, has raised over $40 million for medical research over the last six years, and was set to make a big addition to that after Friday’s event.

You might think Walsh has enough to keep him occupied, including what he described as an eternal battle with the Australian Taxation Office.

“Every 10 years I lose. And in between I do not win,” he joked.

But he’s also taking aim at a curious but common problem: queuing. He and a team is working on technology that will use location services to try to eliminate queues in settings such as restaurants. It’s a little example of how one of Australia’s most fascinating minds keeps whirring, and looking forward.

“The future is foreign country, but I think it’s worth visiting,” Walsh said. “The future is worth the risk.”
