Tesla's April Fool's Joke Spoofs Market Algorithms

Posted by timothy on from the be-prepared-for-next-year dept.

Okian Warrior writes Yesterday, Tesla's twitter feed and blog announced the new "W" Model. Meaning "Watch" (as in "wristwatch"), the announcement Included a photo of a watch spouting a cumbersome "Big Ben" glued to the face and including this text: "This incredible new device from Tesla doesn't just tell the time, it also tells the date. What's more, it is infinitely adjustable, able to tell the time no matter where you are on Earth. Japan, Timbuktu, California, anywhere! This will change your life. Reality as you know it will never be the same." Clearly, this was an April fool's joke as anyone who reads more than just the headline would immediately guess. The problem is that Bloomberg's fast response team did not. The algos, on massive volume, spiked TSLA stock higher by nearly 1%.

    A 1% move on an individual stock is not that much, is this really a big problem?

      When you're trading in volume by the millisecond for pennies, a $2 swing for an April Fools joke would be a pretty big deal I'd think.

      Well, think about it ... say you could pretty much push the value of any stock by 1% just by having your idiot boxes start actively trading.

      If you're the brokerage house, you can make a lot of money by planning to cause the price to briefly blip and then make money on the differences.

      A brokerage house shouldn't be able to change the price of a stock like that.

      Doing it based on a joke tells me just how damned broken that method of trading is. And since all of the trading houses have these algorithms, it's not unprecedented for them to set off a chain reaction.

      Basically a bunch of self-serving greedy bastards can materially impact the stock market any time they like .. even if they don't intend to. All to try to rip off money from the market

      Check out the actual bump.

      Anecdotal of course, but it sure seems like the announcement caused a massive spike in trading.

      Also note that TSLA is up $4 over yesterday's close, so that's a total of 3%.

      This is not nothing, given the scope of effort they made (a simple blog post and twitter announcement).

      Excuse me while I play the worlds smallest violin for the financial addicts on Wall Street.

      You want to gamble by the millisecond, learn to live with winning and losing at that same rate.

      Once the algos learn to discount press releases on April 1st, that's when companies start scheduling their bad news for that date.

      Indeed. That high frequency trading has resulted in a single point of failure is the real story here. If bloomberg announced this to a bunch of humans, some would buy without thinking, a smaller amount would buy cause they're stupid but most would just laugh at bloomberg's mistake. Computers don't get jokes. Every time a previously unknown trigger occurs there is a chance a feedback loop will blow something up.

      380 days? That's not how exponential functions work. They clearly assumed 365 days: 1.01^365 = 37.78 (an extra 0.6 day would hit 38 exactly). With 380 days you'd be at 43.87, or with only 260 trading days that would be 13.29x

      Most stocks fluctuate more than 1% in a day.

      Outside of a market crisis, they sure as fuck do not.

      Yes they do. Besides Tesla, other companies that fluctuated more than 1% today include Microsoft, General Motors, Exxon, etc. Small companies tend to fluctuate even more. Perhaps you are thinking of the overall market average, which tends to fluctuate far less, because the individual companies generally do not move in unison.

    So the stock market is being actively manipulated by idiots?

    As usual, these people are just parasites on the financial system looking to skim off money before everyone else has a chance.

    High frequency trading is essentially skimming off the top for yourself without having done ANYTHING other than having a faster connection.

    I hope these clowns bankrupt themselves one day with their stupidity.

      That wasn't high frequency trading, it was bad loans. Bad loans to people who wanted to buy houses. So the greedy children who just had to have that house they couldn't afford caused an economic crash. The clowns just let them do it.

      It wasn't only bad loans.

      It was the wholesale fraud which happened when bankers packaged up bad loans, and with the help of ratings agencies passed them off as AAA investment, and then hoodwinked the rest of the world into buying it. It was a scam on a massive scale.

      Essentially Wall Street and the financial industry made HUGE mistakes in who they loaned money to, and the lied to everybody else as they pawned off the debt.

      It was a fucking pyramid scheme, ran by con artists, and then foisted off onto everybody else.

      Had it only been bad loans, the idiots who made those loans would have been the ones to get hurt. But this was basically kiting checks and outright falsifying documents.

      This wasn't caused by people who bought houses they couldn't afford. This was theft by the financial industry to cover their own stupid losses.

      The scam could only have worked because the ratings agencies are complete whores who don't actually do anything meaningful other than "if you pay us, we'll say anything you want".

    No, based off what happened last time, they don't go bankrupt. They don't go to jail.

    Everyone else's retirement funds take a huge hit and lose value, but assholes^H^H^H^H business leaders like this are too important to fail.

    Don't laugh, cry. We slog all day and then dutifully maxout our 401Ks and "invest" in mutual funds and other such instruments.

    While these thieves on the other end are high on opium (OPM= other people's money) rolling high, taking insane risks, and all the profits and bonuses are theirs. If they make a loss, they are too big to fail and our taxes will bail them out. If they blatantly lie, cheat and commit felonies, they are too big to jail too.

    Realize this. The. joke. is. on. us. They are laughing all the way to the bank (which they own probably).
