"After having lost some 10 percent of its value the week before, the Dow Jones Industrial Index fell 508 points, or 22.6 percent, on Black Monday, wiping out $500 billion in what was, at that time, the biggest-ever one-day stock-market loss to date."

It took roughly two years for the DOW to recover to pre-Oct levels.

The regulators has since introduced crash protection via circuit breakers, so that trading stops if it were to plunge. Even during the great financial crisis in 2008, the largest single one day fall was 8%.

How prepared are you for another Black Monday if it were to occur ?

• Most of us will probably shrug our shoulders and carry on,
• the smarter ones amongst us will probably deploy the cash that has been sitting on the sidelines.
• Those who borrowed money could face a margin call.
• Those who shorted the market are probably laughing all the way to the bank.

By the way, this is a great video capturing the mood of that week.
