I'm opening my Roth IRA Account.
My question is: How often should I adjust my portfolio? I know this depends on a variety of factors: I'm 23, plan to retire when I'm in my 60s (or at least withdraw from this fund at that time). So my "target" retirement date is ~2057.
Right now, because of my age, I'm investing solely in ETFs (VTI, VOO, VT).
I know the old rule-of-thumb: subtract your age from 100 and that's how much you should be investing in stocks.
With the longevity of human life, and I can only imagine that this is going to increase substantially in my lifetime, I'm considering the 'new' rule-of-thumb: subtract your age from ~120 and that's how much you should be investing in stocks.
According to this logic I should have ~97% of my money in stocks, but I think it's safe to just do all 100% for ease.
How often should I adjust this? I'm not planning on readjusting my portfolio by 1% annually. Should I be doing this every 5 years? 10? This question may be ambiguous and varies by investor, but I'm looking to try to maximize my portfolio, and at what time may be best to adjust.
