Vanguard Fund Correlation Tool

Given today’s financial climate, diversification is the key.  As someone who holds several mutual funds, I look for Morningstar rating, past performance, risk measures (alpha, beta, R-squared, standard deviation, sharp ratio), etc.  But, if you have some Vanguard Mutual Funds, you may be interested in this Vanguard Fund Correlation Tool (it’s in the lower right column).  It allows you to determine how correlated one Vanguard Mutual Fund is to another Vanguard Mutual Fund.  For instance, Vanguard MidCap Growth Index (VMGIX) is very highly (0.97) correlated with Vanguard SmallCap Growth Index (VISGX).  So, if you’re thinking of investing some money into different Vanguard Mutual Funds (e.g. Roth IRAs) and want to diversify (i.e. achieve low correlation between funds), check out the correlation tool.  I wish there was a tool for all the mutual funds, not just Vanguard funds, and am thinking of writing the tool myself…

Last 2008 Estimated Tax Due!

The last (of 4) payment for 2008 estimated taxes is due on Thu, Jan 15, 2009, that is if you don’t plan on filing your taxes by Feb 2, 2009.

In most cases, for 2008, you must make estimated tax payments if you expect to owe at least $1,000 in tax for 2008 (after subtracting your withholding and credits) and you expect your withholding and credits to be less than the smaller of:

  1. 90% of the tax shown on your 2008 tax return, or
  2. 100% of the tax shown on your 2007 tax return (110% if your 2007 adjusted gross income is more than $150,000)
