Autocorrelation of returns can be used as a proxy measure for liquidity of the asset.
The degree of serial correlation in an asset’s returns can be viewed as a proxy for the magnitude of the frictions, and illiquidity is one of the most common forms of such frictions.
A strongly liquid asset should reveal no serial autocorrelation.
You can perhaps build ...
I believe the document that @clarkmaio referred to is Minimum capital requirements for market risk and the issue described can be found on page 52.
As explained here:
The revised FRTB rules require ES to be calculated using a base liquidity horizon of 10-days and this ES to be scaled by mapping each risk factor to one of the risk categories below:
Couple points for your consideration:
At the time of order execution: You are most likely a liquidity taker and thus are rendered a service by those that provide liquidity and you compete for taking liquidity with other takers in the market. As such you need to have a firm grasp at the market impact of your order.
Liquidity can be extremely dynamic even ...
Interesting question. The one book I heard about is "Market Risk Analysis" by Carol Alexander. However I think you should try to search for some company specific materials. Sometimes big banks like Credit-Suisse or Deutche Bank publish some materials which are hard-to-find by other means.
Lookup something like "free FRM exam" or "FRM exercises". Here is a free exam from GARP itself, with explanations:
I hope this helps
I'm not an expert of market risk, but, as regards the market risk references I know, the best one and more related to the question posted above is Dynamic Hedging by N. N. Taleb.
Here below you can find the full reference:
Taleb, Nassim. Dynamic hedging: managing vanilla and exotic options.
Vol. 64. John Wiley & Sons, 1997.
It concentrates the ...
A CFO typically is not involved in managing risk, though that's not always the case.
If your hypothetical CFO is involved in the day-to-day managing of FX risk, the following could be useful:
VaR & Stressed VaR
Correlation between traded currency pairs
If your hypothetical CFO isn't involved in the day-to-...
For business purposes, a CFO/CEO typically won't be interested at low-level modeling. Metrics such as:
Maximum portfolio gross/net exposure (hence gross/net leverage)
Maximum per trade size per product
Maximum intraday exposure per product
are probably among the more important ones for business decisions.
There are many ways to do this. Some are more computationally intense than others. Some are more realistic than others.
If you want to stay in CreditMetrics universe I would jointly simulate systemic variables impacting credit AND interest rate variables. This can be done in a Gaussian setting quite easily (eg Hull White for interest rate and drift+...
