Summary

Learn the fundamentals of portfolio construction — asset allocation, diversification, and rebalancing — using your $100,000 TradeHQ virtual cash.

Source-check scope

Source check: 2026-10-31. Limited source and arithmetic check: SEC Investor.gov diversification guidance and the hypothetical 25% × 30% × $100,000 = $7,500 sector-loss example were checked. No asset allocation or rebalancing schedule is recommended.

The Foundation: Asset Allocation

Asset allocation divides a portfolio across selected asset classes or holdings. Its effect depends on exposures, correlations and the period examined. Allocation does not guarantee diversification or performance; document the assumptions rather than rank it as universally more important than every other decision.

For a virtual accounting example, choose percentages that total 100%, such as 60% in a stock-index example, 30% cash and 10% another practice asset. These numbers illustrate weighting only. Compare another normalized allocation and identify overlapping holdings and concentration.

Real-money allocation depends on circumstances including objectives, time horizon, liabilities and ability to bear loss. Age alone cannot determine a suitable stock/bond split. A simulator can compare hypothetical exposures, but it cannot discover a person's true risk tolerance or certify an investment allocation.

Diversification: Don't Put All Eggs in One Basket

Diversification distributes selected exposures but cannot prevent several holdings declining together. For arithmetic practice, if a sector is 25% of a $100,000 virtual portfolio and falls 30% while everything else stays unchanged, that sector contributes a $7,500 loss before costs. Actual results depend on overlapping holdings and how other prices change.

Compare exposures by issuer, sector, geography, currency and economic sensitivity. More tickers do not necessarily mean less concentration when holdings overlap. An index fund provides a specified basket, not every type of protection.

Compare a concentrated virtual portfolio with one spread across different practice exposures. Keep total starting value and observation period equal and record each contribution to gains and losses. A commodity or ETF is not an assured hedge; correlations and fund holdings can change.

Rebalancing and Ongoing Management

Portfolio weights can drift as holdings change in value. In a hypothetical portfolio with no cash flows, a 50% crypto gain and a 10% stock gain increase crypto's relative weight. This changes sensitivity to crypto; the calculation alone does not determine the portfolio's overall risk. Rebalancing adjusts toward selected target weights through purchases, sales or new contributions where available. Targets are study assumptions, and fees, taxes and subsequent price changes affect the comparison. Rebalancing does not guarantee smaller losses or higher returns.

Rebalancing restores selected target weights. Timing and thresholds are choices to compare, not universal quarterly or five-percent rules. Rebalancing can add costs and can reduce returns in a continuing trend, so record turnover and compare against a portfolio left unchanged.

For an educational rebalancing worksheet, set hypothetical weights, recalculate them after invented price changes and quantify the effect of virtual transaction fees. Compare the adjusted portfolio with one left unchanged. No allocation, monthly schedule or calculated benefit should be treated as a recommendation for a real account.
