A margin call is a demand from your brokerage for you to add money to your account or closeout positions to bring your account back to the required level. As an example, assume the $1,000 of shares purchased above loses 3/4 of its value, so it is now worth just $250. The cash in your account has fallen to 3/4 of its original amount, so it has gone from $500 to $125. You will need to add money to your account to cover that since your shares are not worth nearly enough at this point to make up the loan amount.


If your company sells products, profit margin is the number that drives every other part of the business. Out of the profit margin comes the money to pay expenses and the net profits for you, the owner.

In general, your profit margin determines how healthy your company is – with low margins you’re dancing on thin ice and any change for the worse may result in big trouble.

In the principle of investing, the margin of safety is the difference between the intrinsic value of a stock against its prevailing market price. Intrinsic value is the actual worth of a company’s asset, or the present value of an asset when adding up the total discounted future income generated.

There isn’t a universally accepted way to determine intrinsic worth, but it’s most often estimated by analyzing a company’s fundamentals. Like bargain hunters, the value investor searches for stocks believed to be undervalued by the market, or stocks that are valuable but not recognized by the majority of other buyers. A margin account lets investors borrow funds from their broker in order to augment the buying power in their account, using leverage. This means that with 50% margin, you can buy $1,000 worth of stocks with just $500 cash in the account – the other $500 being loaned by your broker. If Broker XYZ changes its minimum margin requirement from $1,000 to $2,000, Mary’s margin account with a stock value of $1,500 now falls below the new requirement.

Minimum margin is the amount of funds that must be deposited with a broker by a margin account customer. With a margin account, you are able to borrow money from your broker to purchase stocks or other trading instruments. Once a margin account has been approved and funded, you are able to borrow up to a certain percentage of the purchase price of the transaction. However, just as with any loan, you must repay the money lent to you by your brokerage. Value investors look for securities with prices that are unjustifiably low based on their intrinsic worth.

A high-profit margin indicates the company is executing its business well, but increasing margins mean management has been extremely efficient and successful at controlling expenses. Mary’s margin account net value is $1,500, which is above her broker’s minimum requirement of $1,000.

Accounting for Management

The margin of safety principle was popularized by famed British-born American investorBenjamin Graham (known as the father of value investing) and his followers, most notably Warren Buffett. Investors utilize both qualitative and quantitative factors, including firm management, governance, industry performance, assets and earnings, to determine a security’s intrinsic value. The market price is then used as the point of comparison to calculate the margin of safety. Margin of safety is a principle of investing in which an investor only purchases securities when theirmarket price is significantly below their intrinsic value. In other words, when the market price of a security is significantly below your estimation of its intrinsic value, the difference is the margin of safety.

Can I use all my portfolio as collateral ($11,000 after purchase)? I have seen that the excess is maintained in a SMA, so I’m confused and this can’t be used to meet the margin call (only cash).

Many value investors do not support the efficient market hypothesis (EMH). This theory suggests that stocks always trade at their fair value, which makes it harder for investors to either buy stocks that areundervalued or sell them at inflated prices.

For investors, the margin of safety serves as a cushion against errors in calculation. Since fair value is difficult to accurately predict, safety margins protect investors from poor decisions and downturns in the market. Taking into account a margin of safety when investing provides a cushion against errors in analyst judgment or calculation.

Because investors may set a margin of safety in accordance with their own risk preferences, buying securities when this difference is present allows an investment to be made with minimal downside risk. A company’s profitability depends not only on having a good profit margin, but also on consistently increasing it. For a good indication of historical profit margins, investors should look back at least five years.

It does not, however, guarantee a successful investment, largely because determining a company’s “true” worth, or intrinsic value, is highly subjective. Investors and analysts may have a different method for calculating intrinsic value, and rarely are they exactly accurate and precise. In addition, it’s notoriously difficult to predict a company’s earnings or revenue. He looks at each company as a whole, so he chooses stocks solely based on their overall potential as a company. Holding these stocks as a long-term play, Buffett doesn’t seek capital gain, but ownership in quality companies extremely capable of generating earnings.
