How to Rebalance Portfolio with i3DIY

Portfolio rebalancing is the critical procedure for portfolio investing and performed in response to changes in asset value and allocation. The calculation of shares (Stock or ETF) or amount (Mutual Fund) for rebalancing must consider to reduce the transaction cost and avoid short-term capital gains. This article described the process step by step on how to use i3DIY Smart Rebalancing to achieve the above purpose.

When carrying out the Portfolio Rebalancing, you must consider the following points:

Determine your target Portfolio

The target portfolio is the asset allocation of specific assets. You can build your target portfolio bases on financial goals, risk tolerance, target return, or referring to financial media such as Kiplinger and Morningstar. Ownla LLC is not an investment advisor and cannot provide portfolio advice.

When to Rebalance your Portfolio

Because the market is volatile, the difference between the current and target asset allocation must be calculated every day. If the difference exceeds a threshold (usually 5%), you need to perform Portfolio Rebalancing.If the difference exceeds a threshold (usually 5%), the Portfolio Rebalancing is performed.

Calculate the Buy/Sell Shares

If you are investing in mutual funds, it is straightforward to calculate the amount of the transaction.

You can use the spreadsheet to calculate the excess or insufficient amount of the allocation. However, if it is an ETF or a stock, the buy/sell orders are put by the number of shares. These require complicated calculations.

Brokerage Transaction Cost

The cost of rebalancing should also be considered.

If your portfolio consists of five stocks or ETFs with a $10,000 asset value, the brokerage transaction fee is $ 7 per order. The cost of rebalancing is $ 35 a year or 0.35% of the asset.

If your portfolio consists of five mutual funds with the same asset value, the minimum transaction fee is $ 50 per order, and the annual rebalancing cost is $ 250 or 2.5% of the asset.

For those with low investment, the cost of rebalancing will greatly erode their profits.

Short-Term Capital Gain

If you are not investing in tax-advantaged accounts (401(k), 403(b), IRA….), you must consider the taxation on capital gains. If you sell an asset held for one year or less, any profit is considered a short-term capital gain. Short-term capital gains do not benefit from any special tax rate – they are taxed at the same rate as your ordinary income. For 2018, the long-term capital gains tax rates are 0, 15, and 20 percent for most taxpayers.
