According to the NYSE TICK, or uptick minus downtick, index, at precisely 2:43pm, the selling order flood was so big it not only surpassed the acute liquidation that was observed around 3PM on Wednesday, but the -1,793 print was one that had not been seen for 8 years: as Bay Crest Partners technical analyst Jonathan Krinsky wrote, the sudden and violent surge in selling as measured by the TICK index, when downtick volume overpowered upticks, was the lowest reading since the May 6, 2010 “flash crash” when liquidity dried up in markets, sending the market plummeting for a few minutes, as HFT briefly went haywire (or when a spoofer outsmarted the algos, depending on what version of events one believes).

According to estimates from JPMorgan Chase in June 2017, just 10% of all stock-trading volume is the result of investors picking stocks to buy and sell. The remainder of trading volume primarily derives from quantitative-based computer trading. Essentially, we’re talking about computer programs that aim to secure small profits via high-frequency trading (HFT) hundreds or thousands of times a day.
In short selling, the trader borrows stock (usually from his brokerage which holds its clients' shares or its own shares on account to lend to short sellers) then sells it on the market, betting that the price will fall. The trader eventually buys back the stock, making money if the price fell in the meantime and losing money if it rose. Exiting a short position by buying back the stock is called "covering." This strategy may also be used by unscrupulous traders in illiquid or thinly traded markets to artificially lower the price of a stock. Hence most markets either prevent short selling or place restrictions on when and how a short sale can occur. The practice of naked shorting is illegal in most (but not all) stock markets.
Vous voulez investir en bourse, mais vous ne savez pas trop comment vous y prendre? Vous souhaitez empocher les 2-3% de frais de gestion plutôt que de les verser à votre banque? La solution est simple, gérez vous-mêmes vos placements en ligne. Certes, ça requiert un peu plus de temps et d’engagement, mais c’est payant (combien?). En plus des meilleurs rendements, vous bénéficierez de nouvelles connaissances et vous prendrez vraiment le contrôle de vos finances. D’ailleurs, je pense qu’il s’agit d’un passage obligé vers l’indépendance financière. Voici comment procéder.
Weingarten is prone to soliloquies extolling his “world-class, nobody better” forecasting record. Asked to explain his methodology, he answers in gnomic riddles or not at all. The family office guy asks how financial astrology might relate to SpaceX and other efforts to explore beyond Earth. Weingarten cuts him off and says he can’t give him an “informed decision about how children on the moon will be affected.”

(7) Diseases. Disease epidemics could be a worsening problem in 2018 - 2019, including Bird Flu or H3N2 Flu Influenza, and SARS could return -- I think these are diseases that could cause great problems over the next 5 years. And antibiotic resistant bacteria infections. Watch out for worsening worldwide disease epidemics in 2018-2019, including Ebola and Flu and Zika Virus. And this disease epidemic could be Ebola, or swine flu, or Flu strain H3N2 Fujian, which is a severe strain that began as an outbreak in 2003, or it could more likely be bird flu type H5N1 causing a severe epidemic in birds - chickens, ducks, etc.- but that can spread to humans. H3N2 Fujian began in Fujian Province in China, (associating it with the Red Dragon, Red China, in Revelation 12), and bird flu began in Korea in Dec. 2003, but previously there was a 1997 outbreak in Hong Kong, associating it with the dragon. The concern is that bird flu is very deadly to people, and if it mutates to spread from person to person then it could cause a deadly worldwide pandemic in 2018 - 2019. And swine flu began speading worldwide from Mexico in April 2009, see the calendar page and Flu page on it. See the King James Bible Code matrices on diseases, including the possibility of an airborne Ebola outbreak, and a deadly Swine Flu mutation.
By the end of the weekend of November 11, the index stood at 228, a cumulative drop of 40% from the September high. The markets rallied in succeeding months, but it was a temporary recovery that led unsuspecting investors into further losses. The Dow Jones Industrial Average lost 89% of its value before finally bottoming out in July 1932. The crash was followed by the Great Depression, the worst economic crisis of modern times, which plagued the stock market and Wall Street throughout the 1930s.

I do not hold positions in these investments. No recommendations are made by me one way or the other.  If you're an investor, you'd want to look much deeper into each of these situations. You can lose money trading or investing in stocks. Always do your own independent research, due diligence and seek professional advice from a licensed investment advisor.

“ Business ventures with multiple shareholders became popular with commenda contracts in medieval Italy (Greif 2006, 286), and Malmendier (2009) provides evidence that shareholder companies date back to ancient Rome. Yet the title of the world's first stock market deservedly goes to that of seventeenth-century Amsterdam, where an active secondary market in company shares emerged. The two major companies were the Dutch East India Company and the Dutch West India Company, founded in 1602 and 1621. Other companies existed, but they were not as large and constituted a small portion of the stock market. ”
Mais, Warren est plus brillant que la norme, il a aussi compris très jeune le pouvoir de l’épargne, il a bénéficié d’anomalies historiques (crise de 29, croissance de l’après guerre, invention du crédit à la consommation, arrivée de la femme sur le marché du travail, invention de la surconsommation etc…) en plus d’utiliser des outils que nous simples particuliers n’avons pas : la float de compagnies d’assurance (argent des primes qu’il peut investir afin d’en tirer un profit pour lui).
