If you believe the description is wrong, your issue is with the article.
Direct quote from article:
With Reg NMS, it essentially took x amount of available stock at one place, and made it one tenth of that x at ten different places.
If that isn't a regulation forcing large purchases to split up, then it's on you to explain why.
- yummyfajitas 13y agoThe most charitable interpretation of that quote is that after RegNMS, multiple trading venues became legalized. Liquidity providers then chose to spread liquidity out because it was now legal. Here is RegNMS. Find me a place where it says liquidity must be divided between all possible exchanges: https://www.sec.gov/rules/final/34-51808.pdf https://www.sec.gov/rules/final/34-51808.pdf

- theorique 13y agoSeller(s) of stock are not required to place shares on different exchanges. This is a side effect of the process of trading, as the NBBO price bounces around to different venues. If I offer 100,000 AAPL at NBO at exchange X, and you are willing to purchase 100,000 AAPL at NBO, your buy order matches mine exactly and the transaction takes place. This is highly unlikely, of course, that an enormous stock transaction like this ($50M) will take place this way.
