&lt;p&gt;&lt;b&gt;새 문서&lt;/b&gt;&lt;/p&gt;&lt;div&gt;기대수익률과 베타의 관계를 나타내는 &amp;#039;&amp;#039;&amp;#039;SML&amp;#039;&amp;#039;&amp;#039; 등식을 의미한다. &amp;#039;&amp;#039;&amp;#039;CAPM&amp;#039;&amp;#039;&amp;#039;의 수식은 다음과 같다: &amp;lt;br&amp;gt;&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;E(R&amp;#039;&amp;#039;i​&amp;#039;&amp;#039;) = R&amp;#039;&amp;#039;f&amp;#039;&amp;#039; + β&amp;#039;&amp;#039;i&amp;#039;&amp;#039; × [E(R&amp;#039;&amp;#039;M&amp;#039;&amp;#039;)−R&amp;#039;&amp;#039;f&amp;#039;&amp;#039;]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
E(R&amp;#039;&amp;#039;i&amp;#039;&amp;#039;) : 특정 자산 &amp;#039;&amp;#039;i&amp;#039;&amp;#039;의 기대수익률 &amp;lt;br&amp;gt; &lt;br /&gt;
R&amp;#039;&amp;#039;f&amp;#039;&amp;#039; : 무위험 수익률 (risk-free rate) &amp;lt;br&amp;gt;&lt;br /&gt;
​β&amp;#039;&amp;#039;i&amp;#039;&amp;#039; : 자산의 베타계수, 평균 자산과 비교하여 특정 자산이 갖는 체계적 위험의 상대적 크기 &amp;lt;br&amp;gt;&lt;br /&gt;
E(R&amp;#039;&amp;#039;M&amp;#039;&amp;#039;)−R&amp;#039;&amp;#039;f&amp;#039;&amp;#039; : 시장 위험 프리미엄 (market risk premium) &amp;lt;br&amp;gt;&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
====&amp;#039;&amp;#039;&amp;#039;증권시장선&amp;#039;&amp;#039;&amp;#039;(security market line: &amp;#039;&amp;#039;&amp;#039;SML&amp;#039;&amp;#039;&amp;#039;)의 정의====&lt;br /&gt;
기대수익률과 베타계수를 연결한 점들이 이루는 직선을 의미하며 양(+)의 기울기를 갖는다.&lt;br /&gt;
====&amp;#039;&amp;#039;&amp;#039;시장포트폴리오&amp;#039;&amp;#039;&amp;#039;와 베타====&lt;br /&gt;
시장포트폴리오는 시장 내의 모든 자산으로 구성된 포트폴리오를 의미한다. 시장포트폴리오의 베타값은 시장 내의 모든 자산들의 체계적 위험의 평균이므로 1이다. 그러므로 SML의 기울기는 다음과 같다: &amp;lt;br&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{E(R_M) - R_f}{\beta_M} = \frac{E(R_M) - R_f}{1} = E(R_M) - R_f&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====SML과 개별 자산의 위치====&lt;br /&gt;
모든 개별 자산의 기대수익률은 해당 자산의 베타계수와 비례해 SML 상에 위치한다. 어떤 자산의 기대수익률과 베타를 E(R&amp;#039;&amp;#039;i​&amp;#039;&amp;#039;)과 β&amp;#039;&amp;#039;i&amp;#039;&amp;#039;로 표기하여 SML 상에 위치한다고 보면 다음과 같은 식으로 이어진다:&amp;lt;br&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{E(R_i) - R_f}{\beta_i} = E(R_M) - R_f&amp;lt;/math&amp;gt; &amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
이를 다시 정리하면, 자산가가격결정모형이 되는 것이다: &amp;lt;br&amp;gt;&lt;br /&gt;
E(R&amp;#039;&amp;#039;i​&amp;#039;&amp;#039;) = R&amp;#039;&amp;#039;f&amp;#039;&amp;#039; + β&amp;#039;&amp;#039;i&amp;#039;&amp;#039; × [E(R&amp;#039;&amp;#039;M&amp;#039;&amp;#039;)−R&amp;#039;&amp;#039;f&amp;#039;&amp;#039;]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===자기자본비용에 적용하기===&lt;br /&gt;
CAPM을 통해 계산한 E(R&amp;#039;&amp;#039;i&amp;#039;&amp;#039;)는 특정 자산과 주식에 대해 투자자들이 요구하는 기대수익률이기 때문에 &amp;#039;&amp;#039;&amp;#039;자기자본비용&amp;#039;&amp;#039;&amp;#039;(기업이 자본을 조달하기 위해 투자자에게 제공해야 하는 수익률)과 동일한 개념으로 간주될 수 있다.&lt;/div&gt;</summary>
