Why Code in R?

Why Alpha?

Recall that if we have a porfolio of two risky securities, their combined return is

\[E(P)=w_1*E(R_1)+w_2*E(R_2)\] Where \(w_1\) & \(w_2\) are the weighted portion of assets 1&2 in portolio P

The standard deviation of P is in terms of the risk of asset 1 & 2, ie \(\sigma_1\) & \(\sigma_2\) is

\[\sigma(P)=\sqrt{w_1^2 \cdot \sigma_1^2+w_2 \cdot ^2\sigma_2^2+2\rho w_1w_2\sigma_1 \sigma_2}\] Obviuosly, \(\rho <=0\) is optimal as it lead to lower risk in P.

Also recall, from regression analysis, that the intercept term in the fit equation \(y=\beta x+\alpha\) has zero correlation with X by construction. So, if we regress on asset combinations versus our benchmark and find assets with statistically significant intercept terms, or \(\alpha\), to add to the portfolio, we derease the risk of the portfolio.

Why Alpha?

Why Alpha?

w1=w2=1/2
r1=r2=.06
sig1=sig2=.2
rho=.7
sharpe1=(w1*r1+w2*r2)/(sqrt((w1*sig1)^2)+(w2*sig2)^2+2*rho*w1*w2*sig1*sig2)   #typical equity correlation
sharpe1
## [1] 0.483871
rho=.0
sharpe2=(w1*r1+w2*r2)/(sqrt((w1*sig1)^2)+(w2*sig2)^2+2*rho*w1*w2*sig1*sig2)   #zero correlation
sharpe2
## [1] 0.5454545
sharpe2/sharpe1-1    # increase in Sharpe Ratio due to choice of uncorrelated asset
## [1] 0.1272727

Why Alpha?

Say you have a portfolio of $9B that is \(\beta=1\) with the S&P 500.A prudent strategy would be to add assets that are uncorrelated with the S&P 500 for the next $1B.

w1=9;w2=1
r1=r2=.06
sig1=sig2=.2
rho=.7
sharpe1=(w1*r1+w2*r2)/(sqrt((w1*sig1)^2)+(w2*sig2)^2+2*rho*w1*w2*sig1*sig2)   #typical equity correlation
sharpe1
## [1] 0.2559727
rho=.0
sharpe2=(w1*r1+w2*r2)/(sqrt((w1*sig1)^2)+(w2*sig2)^2+2*rho*w1*w2*sig1*sig2)   #zero correlation
sharpe2
## [1] 0.326087
sharpe2/sharpe1-1    # increase in Sharpe Ratio due to choice of uncorrelated asset
## [1] 0.273913

Choosing that next $1B’s allocation will be your final project

What is a Hedge Fund?

“I don’t know what a hedge fund is…”
Ray Dalio, Founder and Chief Investment Officer at Bridgewater ($100B)

What is a Hedge Fund?

“The term ‘hedge fund’ is undefined, including in the federal securities laws. Indeed, there is no commonly accepted universal meaning.”

William H. Donaldson, ex-Chairman, SEC, testimony concerning investor protection

What is a Hedge Fund?

“A fund that charges greater than or equal to 1 and 20, won’t tell you what they’re doing, and often does not hedge.”

Cliff Asness, Partner AQR ($160B)





Regulator definition

Wiki

A hedge fundis a pooled investment vehicle administered by a professional management firm, and often structured as a limited partnership,limited liability company, or similar vehicle. Hedge funds are generally distinct from mutual funds as their use of leverage is not capped by regulators and from private equity funds as the majority of hedge funds invest in relatively liquid assets. Hedge funds invest in a diverse range of markets and use a wide variety of investment styles and financial instruments.

Hedge funds have existed for many decades, but have become increasingly popular in recent years, growing to be one of the world’s major investment vehicles and sources of capital.

Professional Definition

“A hedge fund is a business that attempts to raise and manage client capital successfully. Typically, hedge funds buy/sell liquid securities/derivatives (e.g. not private market securities), employ leverage, and (may) sell short securities.

Hedge fund investment strategies vary substantially and managers are often poor in disclosing their “edge,” this leads to much confusion.”

“Hedge funds attempt to provide “alpha” for their clients’ investments.”
