This bottoms-up approach-starting from simple concepts like return and volatility and building toward bigger ideas like portfolio construction-really demystifies a lot of quantitative finance. It’s great to hear that this framework resonates with you! If you have any follow-up questions or want a deeper dive into any of these steps (like correlation math or t-statistics), just let me know.

@@johntu7484 Thanks for the reply. I'm interested in understanding/constructing financial theory from minimal and robust axioms. If you know of any first-principle optimizations or variables/indicators with apriori backing please let me know. For instance, the simplicity of the Sharpe ratio in combining two fundamental things while, interestingly, being proportional to the t-statistic to add statistical justifiability really hit my sweet spot. In a similar fashion, I'm interested about price indicators with similar properties if there's any.

A great place to start is by laying down a handful of “core assumptions” that tend to underpin most of modern finance. At the top of the list is no-arbitrage-you shouldn’t be able to generate infinite profit with zero risk. Next, risk aversion says that investors demand extra expected return for bearing extra risk (unless the payoff is somehow guaranteed). Then comes time value of money, meaning a dollar today is worth more than a dollar tomorrow. These building blocks naturally lead to constructs like the Capital Asset Pricing Model (CAPM) and mean-variance optimization. Out of these ideas, the Sharpe ratio emerges as a succinct measure of performance: it divides excess return (relative to the risk-free rate) by the standard deviation of returns. It’s particularly elegant because it folds two fundamental things-“reward” and “risk”-into one dimensionless number, and it aligns with a t-statistic interpretation when returns are close to IID normal. If your data or strategy can be (mostly) approximated by these assumptions, Sharpe becomes a fairly robust metric, despite its known limitations in fat-tailed or auto-correlated environments.

8:00 here's some food for thought: in your example, you use negatively correlated instruments to show that mixing them is better than having each one separately, which is true, but here's the thing you missed: even if those instruments were completely UNCORRELATED, it would STILL be better to mix them, you would still get a higher sharp ratio than having just one of them separately.
@bultvidxxxix9973

I would say they are uncorrelated. A negative correlation would mean that if one goes up the other goes down. If that were the case, they couldn't both go up, but they do.
@johntu7484
@johntu7484 23 күн бұрын
Even zero correlation (not just negative) boosts your portfolio’s overall Sharpe ratio as long as you combine the assets in a reasonable weighting. Negative correlation is great, but any correlation below +1 yields a diversification benefit-reducing overall volatility more than it reduces total expected returns, which increases the risk-adjusted return measure.

The Sharpe ratio is not perfect-no single metric is. But it is an excellent, concise summary of how much “reward” you’re getting for the “risk” you bear. Most real-world portfolio construction and hedge fund research starts with Sharpe as a key number, then digs deeper into other risk metrics, factor exposures, and scenario analyses. If you keep these insights (and limitations) in mind, the Sharpe ratio becomes a powerful lens for understanding and improving your investing or trading strategies.

Great video! Its good to point out though that volatillity isnt the same as risk, for example a real estate company could be extremely stable with growing revenue over a 20 year period but then interestrates rise rapidly and this company is using a lot of leverage, all of a sudden this company drops 70% in price after being stable for 20 years. Volatillity and the misspricing of secureties can also create great oppertuneties.

@Will54rol
@Will54rol Ай бұрын
The Sharpe ratio measures risk-adjusted returns. Basically, it shows how much return you're getting for the risk you're taking. A higher Sharpe ratio means your portfolio is performing well relative to the risks involved. It’s a key tool for avoiding overexposure to risky assets, which many investors overlook
@MONROEJACQ
@MONROEJACQ Ай бұрын
Exactly. During market volatility, like we saw in early 2020, portfolios with a poor Sharpe ratio tend to experience greater losses. Many people fail to consider risk-adjusted returns, and that’s where things go wrong. I learned the hard way and lost over 30% of my portfolio back then. That’s when I started working with a financial advisor to avoid costly mistakes
@Churchillhump2268

I can relate. I used to focus only on returns without factoring in the risk. Over time, I realized how critical metrics like the Sharpe ratio are. If you’re not comfortable analyzing this, consider seeking expert guidance. My advisor, Joseph Nick Cahill, specializes in this. He offers free consultations and has helped me achieve long-term stability while minimizing risks. It's a game-changer

Leverage in practice only affects to your required margin per lot, not your pnl. i.e you can open larger positions with smaller account sizes - the risk is higher because you wouldnt be able to open those positions without the leverage due to insufficient margin. High leverage is brilliant to prevent liquidation, given you manage risk appropriately by using bayesian optimized parameters (e.g stop loss delta) in your alpha (as well as factoring in spread costs, comission costs, and swap fees).

the highest level of sharpe ratio in my personal opinion is to ignore all volatility while in profit/above NAV and only measure/weight in the negative volatility. this is because i dont care about volatility spikes induced by large moves up on my portfolio/"winning" variability. and you may question "well why would you have a different average variability while going up on whatever baseline investment compared to while below that? the answer is "i dont know, but you probably dont know either and should check that out"

8:25 This is a fictional situation. You have carefully picked two investments (or made them up) that negatively correlate AND the timeframe is perfect. When is that timeframe perfect? You picked ones “that end up in the same place”. Ok, but what if you picked a point in time where they DIDN’T end up in the same place? Your pretty picture is less pretty and one could argue that by owning both you simply reduced your gains.
