Here is a chronological list of topics, claims, and statements from the transcript:
2
Michael and Brad are accused of falsely accusing thousands and scaring millions of investors to promote a business model. This tactic is likened to building a business on fear, mistrust, and accusation, reflecting either a lack of understanding of market operations or an unwillingness to acknowledge them for business purposes.
3
One speaker is asked if they believe the markets are rigged, a statement they previously made in a book. The speaker confirms their belief that the market is rigged.
4
The speaker who believes the market is rigged also claims the other person is part of the rigging.
5
The responsibility of an exchange or dark pool is to fairly price trades between participants with varying speeds, such as those with microwave towers versus those with internet connections. The market should ensure fair pricing between fast and slow traders.
6
A question is posed regarding the market data Direct Edge uses to price trades. Direct Edge responds that they use a combination of direct feeds and the SIP (Securities Information Processor).
7
One speaker clarifies that 96% of the volume executed on their system comes from customers using proprietary data products, which includes a wide range of firms. They argue that intermediaries have always existed in financial markets, using technology to manage risks.
8
Another speaker argues that the 96% figure refers to proprietary feeds, which is the core of the disagreement. They state that an exchange's view of the market is slower than its fastest participants, leading to different pricing. Allowing collocation diminishes an exchange's ability to fairly price trades because it lacks real-time market awareness.
9
IEX uses direct feeds to price trades and acknowledges it is not as fast as the fastest High-Frequency Trading (HFT) firms. IEX slows down HFTs' ability to react on its exchange, preventing them from profiting from orders placed on IEX.
10
A distinction is made between HFTs providing a valuable service to the market and those seen as "ripping off" the market.
11
A question is raised about whether an aspiring exchange's superior model means all other existing exchange models should be legislated out of business. The goal is to provide a market solution, not to make certain technologies illegal.
12
The term "high frequency trading" should be eliminated from industry vocabulary, preferring "computerized trading." While computers facilitate trading and scalping, orders on an exchange cannot be scalped.
13
Michael Lewis reacts to the initial accusations against Brad Katayama, finding them outrageous and suggesting the accuser is part of the problem. He cites an instance where an investor was disadvantaged on the BATS exchange due to slow price updates.
14
Brad Katayama is portrayed as someone who could have continued to profit from the existing system but instead chose to solve a fundamental problem of unfairness in public exchanges, taking significant risks. The immediate questioning of his motives is deemed incredible.
15
A question is posed about whether the SEC should conduct public hearings to review Reg NMS, a 2007 regulation, to assess its effectiveness.
16
The regulatory process often generates outcomes that are exploited by sophisticated participants. A market solution found by an exchange to address problems is preferable, and investors need more information about how their stock market orders are handled.
17
Michael Lewis denies being an investor in Brad's exchange. He explains that his book's research led him to Brad, whom many investors identified as an honest broker, and that he was investigating market issues rather than seeking specific investments.
18
BATS and Direct Edge became major stock markets by providing value to customers, not by instilling fear. The claim that they tried to scare people is disputed as untrue and inappropriate.
19
There is agreement that the market structure needs re-examination, with calls for a holistic review having existed for years. The SEC chairman is prioritizing this, which is seen as a positive step, provided the review is constructive and data-driven, rather than based on accusations.
20
Brad's business, IEX, has experienced thousands of inquiries and positive responses, indicating increased interest and potential for improved investor confidence.
21
Household ownership of equities has declined from 65% to 52% over the last six years, despite the S&P tripling since 2009. This trend challenges claims of high market confidence.
22
Goldman Sachs has backed Brad Katayama's exchange. A contradiction is highlighted, questioning why Goldman's support for IEX is seen as virtuous, while their investment in other exchanges might be viewed as corrupt.
23
Brad claims his exchange is owned by mutual funds, hedge funds, and others, not primarily by intermediaries or HFTs. The market's purpose is to help companies raise capital and investors allocate it, and a market should not be built specifically for intermediaries.
24
IEX has support from buy-side firms, various brokers, computerized traders not engaged in scalping, and the general public, indicating broad industry backing for its solution.
25
Competition in the market is supported, with the belief that a superior model will prevail. The market should not be built on the premise that one group is exploiting another.
26
Michael Lewis states he visited BATS on February 5th, 2013, in Kansas City with Brad Katayama to observe where high-frequency traders connected. This account is disputed by the other speaker, who claims Lewis did not contact anyone at BATS and his book contains inaccuracies.
27
Lewis explains he was curious if BATS' location outside the Lincoln Tunnel was intentionally chosen to facilitate front-running orders. He attempted to contact Dave Cummings, a BATS founder, but was unsuccessful.
28
The book "Flash Boys" and its media coverage are expected to create a negative public image for high-frequency exchanges and the industry.
29
Electronic trading has brought significant benefits, including narrower spreads (from 12-25 cents to a penny) and reduced institutional investor execution costs (by 90-95%). While the market is not perfect, it is not "rigged" in the way implied.
30
Market imperfections can be seen as an "edge" that hedge funds and pension funds use to make money. Intermediaries are necessary to manage large trades and deserve compensation, which has significantly decreased to fractions of a cent per share due to technology.
31
Brad confirms that IEX is not against intermediaries or those who charge small fees for legitimate services. The issue is with a market structure that favors specific intermediaries or allows scalping.
32
The term "rigged" is emotionally charged and raises concerns among the general public about the safety of investing. Michael Lewis suggests readers consult his book to form their own conclusion on whether the market is rigged.
33
Investor confidence is undermined when market issues like the Flash Crash are downplayed. Providing transparent and truthful information to the public empowers them to make better decisions.
34
Michael Lewis states he is a conservative investor, primarily holding index funds without timing the market. While some subjects in his book withdrew investments, he believes the book's purpose is to incite reform and action, not panic.
35
High-frequency traders supply liquidity, but the term "liquidity" is often misused and is not synonymous with volume. True liquidity involves taking market risk. It is difficult to determine what portion of HFT activity constitutes scalping versus providing genuine market service through clever strategies.
36
When exchanges or networks offer speed to HFTs, not all firms respond equally. Some HFTs indicate that extreme speed is less critical to their operations because their value comes from sophisticated strategies, not just outmaneuvering others.
37
Michael Lewis notes that the FBI launched an investigation since his book's release, and the New York Attorney General is interested in the subject. He believes the FBI investigation was already underway. He aims for a clean and fair marketplace.
