Allocation proposal for Roth IRA

Allocation draft for a long-term (~30 yrs) Roth IRA. Goal is to maximize the amount of money I can have at retirement by diversifying where my money is invested. Will maxing this account out every year that I can, which I bet will be every year. Think I’m able to hold these assets through thick and thin without panic selling, and I also have time on my side to tolerate market volatility and dips. Exclusively ETF’s, think its the best way to invest as broadly as I can, all have been selected for the lowest possible ER in its respective category.

———-

Core = ~55% broad US index funds (~40% of SPYM, ~15% of VTI)

RATIONALE – Exposure to the 500 largest domestic companies, adds massive diversity as a starting point, almost guaranteed substantial growth by following the underlying index, and main anchor of my portfolio long term (~35 years). Adding a total US market fund to this core component for exposure to mid and small cap companies with potential for growth as well

———–

Ex-US component = ~20% (VXUS)

RATIONALE – Exposure to the entire foreign stock market to also benefit from growth in the international economy, also beneficial for periods when the foreign market outperforms the domestic market, which I believe has partially been the case in recent decades.

———-

Growth component = ~10% (QQQM)

RATIONAL – Exposure to the few highest-performing domestic companies that are expected to grow much faster than most others and keep my investment earnings in a sharper upwards trend. More volatile, am comfortable with this, I have the time (\~35 yrs) to tolerate aggressive dips and fluctuations. I promise I won’t panic-sell.

———-

Value Component = ~10% (SCHD)

RATIONALE – Exposure to stock from companies that are estimated to be undervalued, of sound business practices and projected to turn steady, reliable profits over the long term. Meant to balance out my previously mentioned, more volatile growth component. Also great for consistent dividend payments that can be used as reinvested earnings and keep my portfolio compounding even more.

———–

Bet Component = ~5% (MPLY)

RATIONALE – ETF that holds companies selected for dominance in their respective markets and screens for characteristics like pricing power, limited competition and limited regulations. I know this ETF can be seen as attempting to beat the market and performance chasing, but I’ve read up on the strategy, am partially convinced of it being effective, and wish to allocate a small part of my capital to give it shot. Will reevaluate this allocation in one year from the date of investment.

I understand that some of these funds have lots of overlap with eachother, but my reasoning for dipping into all of them is that each fund has its own characteristics that I think can add certain value to a portfolio that the others may not. Being that each fund has its own selection methology, the holdings in each are weighted differently, thus having a different effect on the capital invested in it and playing a distinct role as a component of a larger portfolio.

I am an absolutely brand-new retail investor that has done a lot a learning on the topic of markets and investments from sources I think are reliable, and I think I’ve gotten a pretty good enough grasp of the fundamentals to start this journey. That being said, I may have a skewed understanding of some of this and would some feed-back from investors with more knowledge and experience than me.
