Searching For Lost Money

8/25/2020

Everybody should look into how to obtain his or her lost funds from their local state. What we did here was go into https://ouf.osc.state.ny.us/ouf/, and believe it or not, we received a few hundred to a few thousand dollars per occurrence. The next interesting thing one can do with real estate, is to grieve  property taxes every year. The next step is to hire a property tax attorney on a contingency basis. If the property tax attorney wins for a given tax year, the owner of the home will be responsible to pay the attorney 50% of tax winnings. Some properties we have tested have had property taxes reduced by about 50% or more. It's important to grieve property taxes every single year, as no payment is owed if the property tax attorney doesn't win. Please note that we do not receive any financial incentives for recommending this law firm, but we have had several success stories by using heller tax grievance.

How To Measure Stock Correlations

8/10/2020

Correlation is a bivariate analysis that measures the strength of association between two variables and the direction of the relationship.  In terms of the strength of relationship, the value of the correlation coefficient varies between +1 and -1.  A value of ± 1 indicates a perfect degree of association between the two variables.

There are many things one can do with correlations of stocks in a portfolio. Ideally, every security one adds would not be related. Unfortunately, if you read how exposed are you in the next stock market crash? You will see just about everything moves together during panics because investors move into cash. Also, if you read limitations of financial models, you will also understand that most stocks are actually not normally distributed.

​Whenever correlations are measured, typically a 3 month rolling moving average is computed. For the purpose of this exercise, we just took a basket of securities, and calculated three separate correlations over one year.

Ideally, everything in your portfolio shouldn't correlate together. Similarly, the correlations computed were Pearson (which unfortunately assumes a normal distribution), kendall, and spearman correlation. Investment Science prefers to take an average of the three measures of correlations. Similarly, each and every position should had a different time horizon (i.e. an investment one year from now or three months from now), a different strategy (some long positions, and some short positions).

So many people we talk to are overly-concentrated in one sector or all long or all short. All of these things could lead to a disaster. Feel free to play around with the spreadsheet we created for Microsoft, and a hypothetical basket of securities. Our product, Investment Lab, did these computations.
