No. This is just one of several places where the laws systematically favor the bulls.

Believe this is not a "law" but a "policy" Regardless, your sentiment is spot-on.

  Its an enforcement policy directed by the SEC. Its effectively a law, you can’t opt out for instance.

    Well, you can choose not to follow laws (but you'll face the consequences if caught!).

You are wrong about that. See T5, T6, and H10 halts.

  Those seem to me be to be directed more at price manipulation of individual stocks (eg pump and dump schemes) than restraining enthusiasm across the whole market. I'm open to correction on this (and will not demand a halt).

  The T5/T6 are not really directional circuit breakers though. They are momentum breakers that don’t bias towards downward momentum.

  Because my google-fu is so bad ... has a major exchange ever actually stopped trading because it gained too much?

I don't know if that's a good way to look at it. It's not just "bears" selling when you have a big drop. It's people who need the money for something and are worried about liquidity. Trading halts may or may not fix that, but that's their purpose.

  > It's people who need the money for something and are worried about liquidity. Then they're doing it wrong. You shouldn't have money that you need immediately in the stock market. Yes, people will do that anyway, but I'm not sure we should cater to those people when the health of the markets as a whole are at stake (assuming circuit breakers are effective; up for debate).

Because bulls and bears aren’t equal. The laws should be favored towards not destroying the economy needlessly.

  Because extremely bull markets are a strong indicator of a bubble the laws should be equal to prevent bubble bubble bubbling.

    Are they? The market reaches all time highs almost every year, so would you say that we spend most of our time in bubbles? It is actually expected that the market will typically go up, not down. Otherwise there would be no difference between investing and gambling.
    - munk-a 7y ago
      It's a question of velocity - markets go up and down all the time... but speed breaks to prevent the market from going down to fast also need to prevent the reverse case - some sudden inexplicable and extreme price spiking. Basically - we should protect against any really dramatic sudden changes as chances are that something is wrong. In the last year the S&P grew ~22% prior to this recent drop, that's fine... and on a day swings in the low single digits might be fine. But if we woke up tomorrow and the S&P had recovered the pre-drop value and then grown 20% over that price - something weird is clearly going on and we should be worried.
