Will AI improve my investment results?

AI can help your investing mainly by lowering costs, automating good behavior, and making information easier to process, not by giving you a magic “beat the market” button. Whether it improves your results depends entirely on how you use it and whether it reinforces, rather than undermines, a disciplined, index‑oriented plan.​

Where AI can genuinely help

  • Decision support: Well‑designed tools can nudge you toward better diversification, appropriate risk levels, and avoiding obvious mistakes, which can modestly improve long‑term outcomes. Some studies find AI models can forecast earnings changes and trading signals more accurately than human analysts in specific contexts, though that does not automatically translate into higher net returns for typical retail portfolios.​
  • Automation and robo‑advisors: Automated services generally build low‑cost, diversified ETF portfolios and rebalance them for you, which mainly helps by keeping you invested, reducing frictions, and preventing behavioral errors.​

Where the benefit is limited or risky

  • “AI trading” platforms: Algorithmic and AI‑driven trading is now widespread, but the edge largely accrues to institutional players with scale, data, and infrastructure; retail access to similar tools does not erase that structural gap. Using AI to chase signals, options strategies or high‑frequency trades can easily increase turnover, costs, and taxes without reliably improving risk‑adjusted returns.​
  • Overtrust and “AI validation”: Many retail investors are seeking AI tools that tell them their portfolio is great or identify “smart” picks, yet early evidence shows these tools can be inaccurate, biased or overconfident, and users may follow them too blindly.​

How to use AI without derailing your plan

  • Treat AI as a tool, not an oracle: Use it for tasks like summarizing disclosures, comparing fees, stress‑testing allocations or checking diversification, while keeping your core in broad, low‑cost index funds that target market returns.​
  • Protect against the downside: Be skeptical of any AI‑branded product promising outperformance or “proprietary” signals, and remember that scams are increasingly using AI buzzwords to appear sophisticated.​

For your specific style

  • Given your preference for total‑market, evidence‑based investing, AI is most likely to help by tightening execution around that same strategy—asset allocation, tax‑loss harvesting, and behavior control—rather than by stock picking or market timing.​
  • A practical approach is to let automation handle the boring, rules‑based parts (rebalancing, cash sweeps, drift monitoring) while you keep high‑level control over risk, costs, and staying the course through noise.

Fixed annuities are poor investments Fixed annuities are often criticized as poor investments for several reasons, despite their reputation for providing stable, predictable income.  Here are the key drawbacks and concerns:   High Fees and Commissions Internal Fees:  Fixed annuities can carry a range of fees, including administrative charges, mortality expense risk fees, and rider fees. These can add up to 2%–4% per year, significantly eroding returns over time. Commissions:  Sales agents and financial advisors often receive high commissions for selling annuities—sometimes as much as 5%–8% of the invested amount. This creates a financial incentive for advisers to recommend them, even when they may not be the best fit for the client. Comparison to Other Investments:  Mutual funds and ETFs typically have much lower fees and commissions, making them more cost-effective for long-term growth. Limited Growth a...

How many investors have outperformed the stock market over the last 20 years? Very few investors have outperformed the stock market over the past 20 years.   Data shows that only about 6% to 8% of actively managed equity funds in the U.S. beat the market over this period, with the vast majority—over 90%—underperforming the S&P 500 or equivalent broad indexes. Percentage of Investors Beating the Market Only 8% of equity funds investing in large companies managed to outperform the market over a recent 20-year span. About 94% of all domestic funds underperformed the S&P 1500 Composite Index from 2005-2024. Over shorter timeframes (5-10 years), typically fewer than 15-20% of fund managers beat the S&P 500, and performance persistence is rare. Why It Is Rare The S&P 500’s high returns have proven immensely difficult to beat, especially as indexing has become popular and markets have ...

The stock market indexes seem to be dominated by a handful of tech stocks, but how is the average stock doing? As of late October/early November 2025, the S&P 500 index excluding the Magnificent Seven stocks (the "Other 493") has delivered a modest year-to-date return of approximately 5.3% to 5.4%. That’s barely more than one third of the performance of the full, market-capitalization-weighted S&P 500 index, which was up around 15.1% to 16% over the same period.  (The Magnificent Seven stocks are Alphabet (Google), Amazon, Apple, Meta (Facebook), Microsoft, Nvidia, and Tesla.) Index Concentration and Market Breadth The S&P 500 Equal Weight Index underperformed the standard, cap-weighted S&P 500 by about 12% in 2024, reflecting the gap between the top performing giants and the rest of the market. Only sectors like utilities, industrials, real estate, and energy outperformed their cap-weighted peers, while tech and consumer-focused sectors were ...
