Was looking at the graph above for the Venezuela Stock Market and the Caracas Stock Exchange Stock Market Index crashed 99.90% over the weekend of March 15th, 2021. It dropped from 2,700,000 to 2,700.

What happened and why did the stocks crash? I can't find anything about it in the news.

    The fact that the "crash" was the elimination of exactly three zeros should inform you that it's something artificial, not an actual crash.

  • @RonJohn Three zeros went away; nothing was lost, three times over.

    A picture is worth a thousand words.... moreso when it is built out of numbers.

  • @Yakk your comment puzzles me, because it seems to imply that I think something was lost, when I said no such thing.

    @ronjohn An @ does not mean "you are wrong". The things that were lost were each nothing; and three of them where lost.

Not a crash, an adjustment. Because of the insane inflation, they have adjusted it periodically by dividing by 1000. Last one was March 2021.

    So it's the market-level equivalent of a stock split -- the numbers change, but the values don't.

    @Mattman944: "Didn't want to bother" is most likely (by Occam's razor): "the tool makers didn't foresee this happening, and so did not add code to address this".

    @Kevin I'm less cynical, but then I am a software developer. So from my "in the trenches" point of view, its more of a "handling this wasn't in our requirements" thing than a "we did the cost benefit analysis and decided against it" thing.

    @sharur: For the programmers in the trenches, yes, it’s “it wasn’t in the requirements”. But those requirements come from somewhere, and the people setting them probably either did a cost-benefit analysis and decided against it, or else it was never big enough on their radar to merit a cost-benefit analysis at all.

    I wonder how many automated software trade bots either bought or sold after that change. It possibly wasn't in their requirements either. May 26 at 11:15
