======Minimum Acceptable Return (MAR)======
Minimum Acceptable Return (also known as the '[[Hurdle Rate]]') is the absolute lowest rate of return an investor is willing to accept for an investment, considering its level of risk. Think of it as your personal high-jump bar for your money. If a potential investment's [[Expected Return]] can't clear this bar, you don't even consider it, no matter how tempting it looks. It's a non-negotiable threshold that acts as a powerful filter, helping you immediately discard opportunities that aren't worth your time or capital. For [[Value Investing|value investors]], the MAR is a cornerstone of investment discipline. It's not just a random number; it's a carefully considered figure based on your other investment options (your [[Opportunity Cost]]), the return you could get from a virtually risk-free investment, and the extra compensation you demand for taking on the specific risks of a particular stock or asset. By setting a firm MAR, you force yourself to only focus on investments that offer a compelling return for the risk involved, preventing you from chasing speculative fads or settling for mediocre performance.
===== Why Is Setting a MAR So Important? =====
Establishing a personal MAR is one of the most powerful moves an investor can make. It transforms you from a passive price-taker into a disciplined, proactive decision-maker.
  * **It Enforces Discipline:** In a market driven by greed and fear, a pre-determined MAR acts as your rational anchor. It stops you from getting swept up in speculative manias or panic-selling during downturns. If a stock doesn't meet your criteria, you simply walk away.
  * **It Quantifies Opportunity Cost:** The MAR forces you to constantly ask the question: "Is this //really// the best use of my capital?" Your MAR should, at a minimum, be what you could earn in your next-best investment idea. This ensures you're always aiming to deploy your money in the most profitable way possible.
  * **It Builds a Margin of Safety:** By demanding a return that is significantly higher than a "safe" investment, you are automatically building a buffer against errors in judgment, bad luck, or unforeseen problems with the business. This is a direct application of the [[Margin of Safety]] principle.
===== How to Determine Your Personal MAR =====
While there's no single magic formula, you can construct a logical and robust MAR by combining a few key ingredients. A common-sense approach looks like this:
**MAR = Risk-Free Rate + Equity Risk Premium + (Optional) Specific Risk Premium**
==== The Building Blocks of MAR ====
=== The Risk-Free Rate: Your Starting Point ===
The [[Risk-Free Rate]] is the theoretical return you could earn on an investment with zero risk. In practice, the yield on short-term government debt, such as U.S. [[Treasury Bills (T-bills)]], is used as a proxy. This is your baseline. Any investment riskier than a T-bill //must// offer a higher return. If a stock offers a potential return of 5% when you can get 4% from the government, is that 1% extra worth the risk of losing your capital? Probably not.
=== The Equity Risk Premium: Your Reward for Bravery ===
The [[Equity Risk Premium (ERP)]] is the excess return that investing in the stock market as a whole provides over the risk-free rate. It's the compensation you get for taking on the general uncertainty of the stock market. Historically, this premium has been around 4-6% in the U.S., but it fluctuates. Adding this to the risk-free rate gives you a basic hurdle for an average-risk stock.
  * **Example:** If the T-bill rate is 4% and you expect an ERP of 5%, your basic MAR would be 9% (4% + 5%).
=== The "You" Factor: Adding a Personal Touch ===
This is where you refine your MAR based on the specific investment and your own standards. You might add a few percentage points for:
  * **Company-Specific Risk:** Is the company in a volatile industry? Is it heavily in debt? Does it face intense competition? The higher the risk, the higher your MAR should be. You can use metrics like [[Beta]] (a measure of a stock's volatility against the market) as a guide, but don't be afraid to use your own judgment.
  * **Your Personal Goals:** If you have ambitious financial goals, you might set a higher MAR to ensure you're only investing in high-conviction ideas that can get you there.
  * **Concentration:** If you run a concentrated portfolio with only a few stocks, you'll likely want a higher MAR for each position to compensate for the lack of diversification.
A value investor might set a personal MAR of 10-15% or even higher, ensuring that every investment they make has a high potential for reward.
===== MAR in Action: A Value Investor's Best Friend =====
==== MAR as a Discount Rate ====
The MAR is most powerful when used as the discount rate in a [[Discounted Cash Flow (DCF)]] analysis. In a DCF, you project a company's future cash flows and then "discount" them back to their value in today's money. By using your personal MAR as the discount rate, you are calculating what the company is worth //to you//, based on the return you demand. If the company's stock is trading for less than your calculated DCF value, you've found a potential bargain that meets your high standards.
==== MAR vs. WACC: A Quick Note ====
Don't confuse your personal MAR with a company's [[Weighted Average Cost of Capital (WACC)]]. The WACC is the average rate of return a company expects to pay to its security holders (both debt and equity) to finance its assets. It is the company's hurdle rate. As an investor, your MAR should almost always be higher than the company's WACC. You are taking more concentrated risk than the company as a whole, and your opportunity costs are different. Always use //your// hurdle rate, not the company's.
