워런 버핏의 1993년 주주서한을 바탕으로 한 투자 리스크 강의. 리스크 정의: 학계는 베타(시장 대비 변동성)로 리스크를 측정하지만, 버핏은 변동성을 리스크로 보지 않는다. 베타 비판: 단일 숫자로 리스크를 정확히 재려는 시도는 잘못되었다는 주장. '정확하게 틀리기보다 대략 맞는 것이 낫다'는 원칙 강조. 예시: 발표자가 대학 재무 수업 경쟁에서 베타 높은 10개 종목을 골랐지만 우승하지 못했다는 일화. 변동성의 가치: 버핏은 변동성을 오히려 환영한다. 시장(미스터 마켓)의 변동은 우량 기업을 비합리적으로 싼 가격에 살 기회를 준다는 논리. 닷컴 버블 사례: 고평가 기술주는 폭락했지만, 월마트처럼 기술 노출이 없는 기업도 2000년 23% 하락했는데 이는 설명이 어렵다고 지적. 반대로 펫닷컴 등 온라인 소매 파산은 월마트에 오히려 이익이었다고 언급. 버핏의 리스크 평가 기준(5가지): 1) 기업의 장기 경제성 예측 확실성 2) 경영진의 역량과 자본 배분 능력 3) 경영진이 이익을 주주에게 돌려주는지 4) 매수 가격 5) 세금과 인플레이션 수준. 한계 인정: 이 기준들도 모호하며 세법·인플레이션·경영진·산업 경제는 시간이 지나며 변한다. 그럼에도 버핏은 이런 모호함을 받아들이는 것이 낫다고 본다. 역량 범위: 자신이 잘 아는 산업(예: 장난감 소매업 종사자는 장난감 제조사 분석에 유리)에만 투자하고, 잘 모르는 분야는 피한다. 결론: 버핏은 소수 기업에 집중 투자하며, 연간 '좋은 아이디어 하나' 정도면 충분하다는 전략을 택한다. 영상은 버핏의 리스크 철학을 학계 베타 방식과 대비해 설명하는 교육 콘텐츠이며, 특정 종목에 대한 가격 방향 예측 발언은 없다.

for today's investment advice from legendary investor Warren Buffett we'll be taking a look at his 1993 letter to shareholders in which Warren Buffett gives us a crash course on his perspective of investment risk Warren Buffett points out that his assessment of investment risk differs from the academic definition of risk in Academia investment risk is normally measured by Beta beta is a statistical calculation that measures the relative volatility of a stock versus the broader Market say the S&P 500 the more volatile a stock is compared to the overall Market the riskier we say it is in simplified terms the overall Market has a beta of one and other Investments are compared to the overall market for example if stock a has a beta of two then on average its price swings are twice that of the market if the market goes up 2% stock a would on average go up 4% if the market goes down 2% then stock a would on average go down by 4% the degree of volatility in a stock is what many Define as risk of a stock Warren Buffett is skeptical of the idea of measuring investment risk with beta employing databases and statistical skills these academics compute with Precision the beta of a Stock's relative volatility in the past and then build Arcane investment and capital allocation theories around this calculation in their hunger for a single statistic to measure risk how however they forget a fundamental principle it is better to be approximately right than precisely wrong true story time in one of my upper level Finance classes the professor held a competition at the beginning of each semester in which students would select the number of stocks 10 I believe and at the end of the semester we would see who had the best performance my strategy was to pick the 10 highest beta stocks hoping for a positive volatile swing to win me the competition a semester was roughly 4 months so you wouldn't win the competition if you pick slow moving companies I didn't win the competition now back to waren Buffett Warren Buffett instead of shying away from volatility welcomes volatility in fact the true investor welcomes volatility Mr Market an obliging fellow who shows up every day to either buy from you or sell to you whichever you wish the more mic depress of this chap is the greater opportunities available to the investor that's true because a wildly fluctuating Market means that irrationally low prices will periodically be attached to solid businesses we can observe warm buffets above thinking during the aftermath of a stock market collapse take the.com bust while it makes sense that tech stocks with high valuations and very little profit Drop Like a Rock due to financial gravity but why would companies that have no real technology exposure be affected by the Doom bust companies like Walmart which saw a 23% decline in the year 2000 if anything it could be argued that the bankruptcy of many online retailers like pets.com benefit benefited Walmart Warren Buffett prefers a more Hands-On approach to assessing the company's risk examining the company's management competitive manages economics of Industry the company operates in and intangibles such as company's brand rather than try to reduce the complex idea of risk down to a single number a single definable number is useful for making calculations writing formulas and academic papers but it's usefulness for properly assessing risk a highly complicated concept is questionable Warren Buffet B down his primary factors when evaluating the risk of a company one the certainty with which the long-term economic characteristics of the business can be evaluated two the certainty with which management can be evaluated both at its ability to realize the full potential of the business and to wisely employ its cash flows three the certainty with which management can be counted on to channel the rewards from the business to the shareholders rather than to itself four the purchase price of the business five the levels of Taxation and inflation that will be experienced and that will determine the degree by which an Investor's purchasing power return is reduced from his gross return now besides the purchasing price which is also debatable all these criterias have a degree of fuzziness to them taxation can change over time due to changing legislation long-term inflation is notoriously difficult to predict management can change with time and long-term economics can also change with time as War admits did we foresee see 30 years ago what would transpire in the television manufacturing or computer industries of course not but the fuzziness of the calculation doesn't bother waren Buffett as he said before it's better to be approximately right than precisely wrong it is better to recognize the limitations of your ability to calculate and assess risk than to try to reduce risk down to a singular number like beta certain companies are easier to assess than others especially given your own specialized knowledge if you're a sales manager for toy retailer like Toys R R Us then you're probably better equipped to analyze and evaluate the risk and potential of toy manufacturers than say biopharmaceutical companies as Warren puts it in many industries of course Charlie and I can't determine whether we're dealing with a pet rock or a Barbie we'll stick instead with the easy cases why search for a Neil ber in a hay stack when one is sitting in plain sight by recognizing his limitations Warren Buffett only invests in businesses that he has confidence that he can assess to a reasonable agree with fuzzy numbers this leads him to invest in a small number of companies as Warren puts it therefore we adopted a strategy that required our being smart and not too smart at that only a very few times indeed we'll now settle for one good idea a year Charlie says it's my turn like And subscribe to the strange Ro the Von channel it's ]
