Where's the part of the equation that factors in the part where you fuck it up due to the fact that you couldn't keep your cool during a major downturn and thus you throw all your hard work for the year down the drain.

The best practice in the capital markets is to invest for most returns with minimum possible risk. Although I'd like to add that no amount of quants can predict the stock prices in the future. Frankly government policies do effect the rise and fall of stocks, so in a way we can say that policy makers do have the power to push and pull the market.
Supernova (3 months ago)
1:07:32 Finally, the truth. Be sure to watch this part. I think the point is that risk measures based on historical data only work during the good times which make them useless when you need them the most. The irony! LOL 1:21:11 Bingo!
Luca (3 months ago)
Lecture, when prepared well, could have been very good. Unfortunately it was not, with gaps in finalizing the proposed use cases/examples. 6 - -. Resonances: portfolio management based on the results of risk/return analyses minimization is clearly working only with the assumption of a small % of actors operating on a blind stupid market. Like using apps for spotting low traffic routes or parks free in a congested metropolis. Once many are using those apps, the system behaviour is fuzzy...even AI is beated by fuzzy algorithms! :)))) So...what's missing are more studies on identifying e.g. the thresholds that change the system and the applicability of shared portfolios approaches, especially wrt stocks. A society full of equally behaving sheeps doesn't work, as in the classic accordion effect while queueing on the highway. I'm always that black sheep that stops the process by dumping the oscillations, and that I do for free.

What if people don't have money to have portfolio, that is the fundamental problem.
Supernova (3 months ago)
Has anyone told these finance professors that asset classes are correlated during market downturns? I don't see how the sharpe ratio or any other ratio protects someone from downside risk. Sharpe ratio tells us nothing about the financials of the investment or economic trends. Sharpe ratio is akin to using statistical data to gamble. The Sharpe ratio is descriptive rather than predictive. I suppose if the Sharpe ratio helps someone sleep at night with a false sense of security then so be it. However, I would not recommend picking investments or adjusting allocations based on this ratio. The one thing that stands true in finance is that if you want a higher reward you have to take higher risk - under fair market conditions. The art of investing comes down to the manager's ability to pick good investments that deliver returns over time. Its not easy to deliver consistent performance which is why few firms do it but most portfolio managers use dribble like Sharpe ratios to justify mediocre returns in the name of diversification.

Prof Xia, I stumbled onto your 16. PM video and surprised to read the negative comments. So, here is a real life portfolio, created using Markowitz portfolio therory explained by Francis and Archer. This portfolio was created based on the Dogs of the Dow starting Jan 1, 2018. The optimal weights are Verizon 2.03%, IBM 5.17%, Pfizer 18.18%, Exxon Mobile 11.87%, Chevron 12.40%, Merck 9.38%, Coca-Cola 6.67%, Cisco 13.75%, P&G 7.87% GE 12.67%. Even with big losses from Exxon, Cisco and GE the ROR as 12/13/2018 is +34.57%.
jason rosen (4 months ago)
Tony Lozano Tony Lozano dogs of the Dow isn’t a set portfolio rather it’s a portfolio that is made up of the 10 Dow component companies that have the biggest dividend that year. Every year on the first trading day in January investors following this theory would rebalance their portfolios according to that years data. It’s just one of those portfolios that just happen to work historically for no real reason.

why would he teach econ if he can make alot more money in the markets?
2RosarioVampire (4 months ago)
He's probably earning a third of a million dollars per year lecturing others in MIT. And unlike the market, his job if he is tenured is guaranteed for life. What other jobs out there in the market returns a high six figure (and sometimes seven figure) while having near zero risk on losing the job itself? Plus if teaching is his passion, why not? Also, he did make loads of money in the market before becoming a professor. He worked at Morgan Stanley for 17 years as Head of Global Structured Rates Trading in New York. This professor probably has more than enough wealth to have retired quite a while ago. I don't think earning is a concern for someone like him who probably regularly get offers from top financial firms in his e-mails.

52:00 B -50% and 100%, shouldn't it be 75%?
Jerry Xu (2 months ago)
let me show you the math so you start with 100% of your equity then in year one you lose 50% of it, therefore, 100% x 50% = 50% of the asset, is what you lost 100%-50% = 50% is what you are left with then in year two you gain 100% therefore, 50% x 100% = 50%, is what you gain from year one you had 50%, so you add another 50% 50% + 50% = 100% hope that helps

These models seem really interesting, but I'm pretty clueless as to the concept of weighted returns; the meaning of std. dev. as he uses it; and how variance applies to any of this. Could anyone clear me up?
Bob gates (2 months ago)
using them as indicators as to how much real outcomes could differ from what is projected. variance, in this case, can show the spread of outcomes that will occur in simple terms, and st dev will show what we can expect as a normal range of outcomes. both used to predict how volatile the outcome will be.

How is Cash an asset class? Doesn't the value of cash decrease over time?
Swapneel Naphade (4 months ago)
+2RosarioVampire Thanks for the clarification. Now, it makes perfect sense.
2RosarioVampire (4 months ago)
+Swapneel Naphade When people consider cash, they consider risk free investments (0 risks). In the US, those are generally considered: (Especially short term) Treasuries (and TIPS), Certificate of Deposits under $250,000, Savings bond. These are considered 0 risk because if the above fails, it means the dollar (cash) is no longer a valid currency since the dollar is run by the faith of the government and the treasury is the government itself. About 32% of the time cash has outperformed the equity market. Now, I'm ignoring long term treasuries here because those have interest rate risks (and hence why it's generally not considered for cash equivalents). However, if you bought US treasuries back when it was guaranteed 15+% a year, then for 30 years, you would have beaten all the market with just cash since you were guaranteed 15% a year for 30 years straight. But those are rare occurrences and something people do not wish to happen (because if government can assure 15+% a year for 30 years in the first place, then the economy is already screwed up).
Swapneel Naphade (7 months ago)
I agree that my knowledge of accounting is close to nil but what I understand is, if you have loads of cash in your hand, its value will decrease overtime due to inflation unless you invest the cash in assets. (Obviously it is not guaranteed that value of your investment will increase overtime. That will depend on how you invest.) This is my definition of "Cash". If there is another definition, please let me know.

Most of the time, we are on the "inefficient frontier". Performance is never always win. It's about knowing how to take losses, whether it being stocks, options, commodities, etc... and learn WELL from mistakes. You learn how it's like being burned when you trade real money in the markets. The difference between AIs and Humans is that AI WILL understand human tendencies and will instant trade to kill day traders, but have no particular advantage towards technical analysis or anything longer than a 3 months time span. Lecturer is a professional professor, but that doesn't necessarily mean he will provide the best trading advice by asking him his experience. His mentioned he a conservative method (play safe, low risk tolerance), but it's a lousy strategy for someone who wants to generate aggressive cash flow.

I would only add that cash is not risk free and that stocks have out-performed commodities over last 100 years.
David (21 days ago)
Commodities, specifically gold, will outperform stocks during a financial crisis. Always good to have some gold for the bad times, because everyone buys gold when the stock market crashes and the price goes way up and the dollar reduces in value which gives a double wammy if you live someone other than the US.
