Over the last 100years, there have been several large stock market crashes that have plagued the American financial system. For example, during the Great Depression of 1929, stock prices dropped to 10% of their previous highs and during the crash of 1987, the market fell more than 20% in one day.
Key Takeaways
- Stock markets tend to go up. This is due to economic growth and continued profits by corporations.
- Sometimes, however, the economy turns or an asset bubble pops—in which case, markets crash.
- Investors who experience a crash can lose money if they sell their positions, instead of waiting it out for a rise.
- Those who have purchased stock on margin may be forced to liquidate at a loss due to margin calls.
Selling After a Crash
Due to the way stocks are traded, investors can lose quite a bit of money if they don't understand how fluctuating share prices affect their wealth. In the simplest sense, investors buy shares at a certain price and can then sell the shares to realize capital gains. However, if dwindling investor interest and a decline in the perceived value of the stock results in a dramatic drop in the stock price, the investor will not realize a gain.
For example, suppose an investor buys 1,000 shares in a company for a total of $1,000. Due to a stock market crash, the price of the shares drops 75%. As a result, the investor's position falls from 1,000 shares worth $1,000 to 1,000 shares worth $250. In this case, if the investor sells the position, they will incur a net loss of $750. However, if the investor doesn't panic and leaves themoney in the investment, there's a good chance they will eventuallyrecoup theloss when the market rebounds.
Remember—while stock markets have historically gone up over time, they also experience bear markets and crashes where investors can and have lost money.
Buying on Margin
Another way an investor can lose large amounts of money ina stock market crash is by buying on margin. In this investment strategy, investors borrow money to make a profit. More specifically, an investor pools their own money along with a very large amount of borrowed money to make a profit on small gains in the stock market. Once the investor sells the position and repays the loan and interest, a small profit will remain.
For example, if an investor borrows $999 from the bank at 5% interestand combines it with $1 of their own savings, that investor will have $1,000 available for investment purposes. If that money is invested in a stock that yields a 6% return, the investor will receive a total of $1,060. After repayingthe loan (with interest), about $11 will be left over as profit. Based on the investor's personal investment of $1, this would represent a return of more than 1,000%.
This strategy certainly works if the market goes up, but if the market crashes, the investor will be in a lot of trouble. For example, if the value of the $1,000 investment drops to $100, the investor will not only lose the dollar they contributed personally but will also owe more than $950 to the bank (that's $950 owed on an initial $1.00 investmentby the investor).
Margin and The Depression
In the events leading up to the Great Depression, many investors used very large margin positions to take advantage of this strategy. However, when the depression hit, these investors worsened their overall financial situationsbecause not only did they lose everything they owned, they also owed large amounts of money. Because lending institutions could not get any money back from investors, many banks had to declare bankruptcy. In order to prevent such events from occurring again, the Securities and Exchange Commissioncreatedregulations that prevent investors from taking large positions on margin.
By taking the long-term view when the market realizes a loss and thinking long and hard before buying on margin, an investor can minimize the amount of money they lose in astock market crash.
