Roth IRA for 30yr old starting investing - Portfolio Review

I understand that starting to invest at 30 yrs old has me at bit of a disadvantage of having a *robust* retirement by 65 (or younger).. But, I also know that if the proper foundation is laid now, there is still a glimmer of hope to live somewhat comfortably in the golden years. Just hoping for some guidance or knowledge from experienced people who could possibly steer me away from “first-timer” mistakes by learning from others past experiences. (Short back-story for reference) Salary is 58k (42k net after taxes - High tax state with 24% tax rate state + federal..) Current savings investing rate is 28.5% of my net income. I have started contributing a Roth 401k with 4% match, have a fully funded 8-month emergency fund, and maxed my Roth IRA with Fidelity for 2025 & 2026. (Total funded Roth IRA as of this moment = $14,500 / Roth 401k = $1,000) Currently holding postions/allocations of… Roth 401k = 100% SPYM (Betterment doesn’t have a ton of options..) Roth IRA = 60% SPYM, 15% VXUS, 15% AVDV, 10% SLYV. (70% U.S / 30% International) (First rookie mistake I realize I have made is I “Lump-Sum Invested” everything at once.. I now know that “Dollar-Cost Averaging” is always the best route to go) *401k is DCA My thought process is having SPYM as a backbone of the portfolio while adding SLYV for a pure Small Cap tilt in the U.S markets.. as well as having a slight bit of VXUS with a tilt towards the Small Cap Internationally to slightly off-set the down years for the U.S market that are eventually bound to come sometime in the near future. Maybe I am getting my information wrong, but it seems as though the markets are shifting here in the U.S from Large Caps to Small Caps being the top dog in the index fund game with the possible interest rate cuts and tariffs activating more small business growth. Plus…VXUS, AVDV, SLYV have decent Dividend Yeild % which makes holding something like SCHD not as much of a priority at this time. -I understand AVDV has slightly a bit higher E.R.. but honestly, if that index alone gives me a return of $100,000 in a Roth IRA over the 30 years that I will have this account.. I think I’d be okay with giving up $350 for that sort of return..🤷‍♂️ -I chose SLYV over VBR or AVUV simply because of the higher yield, lower cost per share, very similar returns for the previous 1yr/2yr/5yr reports.. Also, I have heard this fund to have more true Small Cap value stocks compared to VBR/AVUV having majority Mid/Large cap stocks -VXUS decision was made because I want the broad exposure internationally, but I’m not necessarily sold on the idea of VT and having 20-30% of the holdings not being as productive as other dedicated/specific sector funds would have and fear my investments would be spread too thin for any great returns to form. Also the higher yield is an added bonus.. -SPYM was simply a mathematical calculation.. more shares, lowest E.R compared to other S&P500 funds. It may not be a lot more than I would get with something like VOO or SPY.. but I’ll take every penny I can get. Also, not even going to try and attempt trading “options” at this time, so there is really no appeal for the higher liquidity to get into a high cost per share fund (Maybe I am over thinking this aspect…🤔🤷‍♂️) -I’m thinking of switching my Roth 401k to 75% stocks / 25% bonds just to slightly hedge against any volatility I will have in my Roth IRA. (With my current contributions of 4% and getting a 100% company match.. that equals to $5,000 / year - I can not fathom how I would ever be able to max this out to the limit of 24.5k on a yearly basis..) Depending on how this years returns are.. (especially with all the chaos politically/economically going on in the U.S..) I am willing/open to listening to any advice for changing allocations for 2027 contributions. Maybe using a full years funding on VT or VTI to solidify my current portfolio foundation… Or temporarily shift allocations within my current portfolio away from large caps.?.? I guess, I am just wondering if this is a good foundation to build from with the current environment of this economy outlook and expectations, if there are any alternatives to suggest, if I am on the right track, or if I have a crazy thought process on all of this.. Also, feel free to share your first rookie mistakes you wish you could have a “do-over” when starting to invest. I appreciate your time giving this post a read, and I welcome any and all feedback/personal experiences/advice!🫡
