Explore the history of Black Monday, the 1987 stock market crash. Learn how trade deficits and computerized trading led to the Dow's record 22.6% single-day drop.
The 1987 crash was a powerful lesson in how fragile the system can be when everyone tries to use the same 'safety' strategy at the same time. It showed that when technology-driven insurance depends on being able to sell when everyone else is selling, it’s not really insurance.
Causes of 1987 stock market crash
On October 19, 1987, known as Black Monday, the Dow Jones Industrial Average experienced the largest single-day percentage drop in its history. The market shed 22.6% of its value in a single session, which amounted to a loss of 508 points. This event remains a landmark moment in financial history because the massive crash seemed to come out of nowhere for many investors at the time.
The crash was not caused by a single event but rather a series of tripwires and a perfect intersection of negative factors. Key contributors included massive trade deficits, a falling dollar, and bad economic vibes. Additionally, new computerized trading strategies that were intended to act as insurance actually served as an accelerant, worsening the downward spiral during the crisis because they had not been properly stress-tested.
Computerized trading strategies played a significant role in the Black Monday crash by acting as an accelerant rather than a safety net. These new technologies were supposed to provide a form of insurance for investors, but they had never been tested in a real-world financial crisis. When the market began to fall, these automated systems contributed to the rapid decline, making the 22.6% drop even more severe.
The 1987 crash is often viewed as a financial mystery because while October 19 gets the headlines, the real story began weeks earlier. It involved a messy intersection of economic instability and untested technology. For many, it felt like waking up to a cataclysmic event that lacked a single 'smoking gun,' as it was actually the result of multiple economic factors and technological failures converging at once.

Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!
@ladyInfinity
I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.
@jayallen
The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.
@Raguipa
What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.
@colonyofcreatorsNGO
I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.
@BeFreed user
It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.
@austinakon
I love this app. Used it for several days and I cannot stop listening. Such a great way to start.
@jcrules328
I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.
@DanielCZ
I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.
@BeFreed user
I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.
@Brad
I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!
@BeFreed user
The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.
@jayallen
BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.
@BeFreed user
At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!
@matteo77
BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
