VAnguard-POrtfolio-REbalance VAPORE

Algorithm setup to determine proper spread of Vanguard ETF index funds and adjust with the downloaded vanguards transaction file. Current allocation:

The value depends on overall asset allocation. As in, if the asset allocation is 90% stock and 10% bond, each percentage listed above is a fraction of that 90% or 10%. For US large cap stock, the math is 90% * 22.222%. The values above are stored within constants in the holdings source file and can be changed there. The default stock vs. bond distribution is 90 vs 10 for retirement accounts and 60 vs 40 for brokerage investment accounts. These can be changed through command line arguments.

The algorithm is setup to shift the riskiest assets to the roth account and the less risky assets to the traditional IRA account. This is done to allow for the most growth to happen within the account which does not get taxed.

VTC and BND is included in order to shift money away from government bonds and into AAA corporate bonds. There is also an equal distribution among cap sizes in order to not be over invested in large cap stocks.
