Like navigating busy Southern California freeways, volatility option trading is path dependent: Whether one makes or loses money depends on the path taken from point A to point B – as well as what happens en route. As with the freeways, bypassing traffic and finding an optimal route can make a big difference. As a real world example, driving to downtown Los Angeles from Newport Beach can take anywhere from 45 minutes to four hours depending on the route and road conditions (such as, perhaps, unexpected construction). It’s a dynamic process, as volatility – or “traffic” – can create more volatility.
Bad Ads On Websites
René Ritchie is right to compare ad-exchanges to black-boxes, you never know what you’ll get :
We also have no ability to screen ad exchange ads ahead of time; we get what they give us. We can and have set policies, for example, to disallow autoplay video or audio ads. But we get them anyway, even from Google. Whether advertisers make mistakes or try to sneak around the restrictions and don’t get caught, we can’t tell. It happens, though, all the time.
When bad ads appear, we report them and ask that they be disabled. Since different people in different geographies see different ads, it can be a challenge to identify them, and it can take a while to get them pulled. It’s a horrible process for everyone involved.
It’s so bad, our tech team has been exploring their own “bad ads” extension that would identify any resource-heavy ads that violate our policies, and provide us with better information so the ad network can more easily find and kill them. And yes, we’re well aware of how insane that sounds.
The Day the Computers Betrayed Us
“What we can say is that when things work in new ways, they break in new ways,” Alexis Madrigal wrote in The Atlantic after a glitch waylaid the NASDAQ stock exchange for three hours in 2013, causing a panic.
Bill Gross Didn’t Short China
‘‘Woulda coulda shoulda,’’ he said. ‘‘Obviously I wish I’d shorted a bunch of shares but that’s the bane of the portfolio manager: never happy.”
Robots On Wall Street ?
As automation in financial services grows, computers and algorithms have taken on some of the traditional work of traders, clerks and financial advisers. Now, a host of startups that use artificial intelligence to write news stories and other reports have set their sights on writing work at banks and financial-service companies.
