Usually, HFT programs and computer trading works without a hitch. But once in a while problems do crop up. Back on Aug. 24, 2015, the United States’ three major stock indexes plunged on the open, but would recover much of their losses by midday. Among the reasons blamed for the dip were market makers and HFT traders. With so many stocks within the S&P 500 failing to open on time, and a number of exchange-traded funds under trading halts, HFTs and other high-speed traders shut down their systems, removing much-needed liquidity from the marketplace and exacerbating the early-day decline.
Global cues: The subdued Asian markets have also weighed on market sentiment. Brokers said weakness was seen in most Asian markets as high US yield and good economic data led to fear that investors would move to the US, dampened trading sentiments there. Japan's Nikkei was trading 0.46 per cent down at 23,999 as investors took profit from its recent rally to a 27-year high. Meanwhile, Hong Kong's Hang Seng dipped over 1.50 per cent at 26,628.64.

The real estate market turns downward. Homeowners and commercial property owners often suffer severe financial loss after a stock market crash (like the loss of a job or significantly reduced demand for housing.) That scenario picks up steam and causes demand for new homes and apartments to fall, even as property owners may suddenly be unable to afford their loan payments, leading to property foreclosures and personal bankruptcies.

As the large seller's trades were executed in the futures market, buyers included high-frequency trading firms—trading firms that specialize in high-speed trading and rarely hold on to any given position for very long—and within minutes these high-frequency trading firms started trying to sell the long futures contracts they had just picked up from the mutual fund.[23] The Wall Street Journal quoted the joint report, "'HFTs [then] began to quickly buy and then resell contracts to each other—generating a 'hot-potato' volume effect as the same positions were passed rapidly back and forth.'"[23] The combined sales by the large seller and high-frequency firms quickly drove "the E-Mini price down 3% in just four minutes".[23]
Its pretty obvious she's completely failed. She may as well have said she never wrote the current Brexit deal, Barnier did or Merkel did. In more enlightened times her head would be on a spike by now, down by the Thames. But what do we expect from just the latest traitor to Sovereignty on the list, that includes: Heath, Major, Brown and the rest . . We need a new broom to sweep all this rubbish away, once and for all . .
In 1932, the Pecora Commission was established by the U.S. Senate to study the causes of the crash. The following year, the U.S. Congress passed the Glass–Steagall Act mandating a separation between commercial banks, which take deposits and extend loans, and investment banks, which underwrite, issue, and distribute stocks, bonds, and other securities.

Very interesting comment Mark. Thanks for the insight. I do have doubts about President Trump. He’s never stated that he cares about small business. He didn’t state that when he talks about jobs leaving the US, he’s really talking about decisions by greedy multi-national corporate execs and how they stick it to the government. Your admiration of the Clintons I don’t know about. They’ve all been riding the national debt gravy train at ($20 Trillion now). But really, can you just keep living off of credit cards forever? Trump’s trying to turn things around. Even if morally, he’s at the same level as Bill Clinton, we can give him a try at bringing the good jobs back. You do realize China and India are educating and churning out high tech engineers by the boatload, using your money? Are US companies basically competing with overseas companies funded with American money? That’s not FREE TRADE, that’s tax evasion and outsourcing for cheap labor. Trump’s foolish obsession with Mexico and North Korea, might be a sign his mind isn’t 100%, but without Trump, you’re back on the debt gravy train.
Lana, a lot of people are talking housing crash in many markets, but that could take the whole economy down. Even with a crash, it would still be tough for buyers. The right approach to bring prices down is more housing supply. The governments should provide tax breaks and other incentives for housing development and legislation which promotes new housing projects. Good finding a place you can afford.
Yes, he’s applying national stats only to local markets. It’s difficult to deny the severe housing shortage in most markets inlcuding Los Angeles, New York, San Jose, San Francisco, Dallas, Seattle, detc. He takes aim at Millennials, whose dreams he doesn’t regard as worthy. There are a lot of people who would like to stifle new housing growth as a way to increse the value of their own property investments. As long as they control politics, housing shortages will continue.

In 1979, Atari unveiled the Atari 400 and 800 computers, built around a chipset originally meant for use in a game console, and which retailed for the same price as their respective names. In 1981, IBM introduced the IBM 5150 PC with a $1,565 base price[6] (equivalent to $4,213 in 2017), while Sinclair Research introduced its low-end ZX81 microcomputer for £70 (equivalent to £246 in 2016). By 1982, new desktop computer designs were commonly providing better color graphics and sound than game consoles and personal computer sales were booming. The TI 99/4A and the Atari 400 were both at $349 (equivalent to $885 in 2017), Radio Shack's Color Computer sold at $379 (equivalent to $961 in 2017), and Commodore International had just reduced the price of the VIC-20 to $199 (equivalent to $505 in 2017) and the 64 to $499 (equivalent to $1,265 in 2017).[7][8]
The real estate market could collapse if banks and hedge funds returned to investing in risky financial products. These derivatives were a major cause of the financial crisis. Banks sliced up mortgages and resold them in mortgage-backed securities. These securities were a bigger business than the mortgages themselves. That's why banks sold mortgages to just about anyone. They needed them to support the derivatives. They sliced them up so that bad mortgages were hidden in bundles with good ones. Then when borrowers defaulted, all the derivatives were suspected of being bad.
So, the way to prepare for a market crash is not necessarily to artfully predict in advance, and step aside when the crash comes. That's virtually impossible. Rather, it can be useful to consider your overall investment strategy ahead of time, so that you know you could stomach the next inevitable crash when it comes. Ideally, through proper diversification and forethought you'll have an investment approach that will enable you to ride out a crash, rather than turning you into another panicked seller. If you only act on these issues when the crash comes, it will likely be too late.
