Building a stock portfolio with limited capital is hard. You want variety, but you fear spreading too thin. Here is how to split small money across stocks without loading up one sector.

Set Your Sector Limits First

Before buying any stock, decide how much one sector can hold. This stops concentration risk before it starts.

Table 1: Recommended Maximum Sector Exposure by Portfolio Size
Total CapitalMax Per SectorNumber of SectorsStocks per Sector
Under $5,00025%4-5 sectors1-2 stocks
$5,000 - $10,00020%5-7 sectors1-2 stocks
$10,000 - $25,00015%7-10 sectors1-3 stocks
$25,000+10-12%8-12 sectors2-4 stocks

Smaller accounts need loose limits. Bigger accounts can afford tighter spreads.

Maya has $4,000 to invest. She sets 25% as her max per sector. That means no more than $1,000 goes to tech, or healthcare, or any single area.

This simple cap saves her from a bad surprise if one industry crashes.

Use Equal-Weight Position Sizing

With small money, equal-weight sizing keeps things fair. Every stock gets the same slice. No single pick can tank your whole plan.

Table 2: Position Sizes for a $6,000 Portfolio
Number of StocksDollars EachPercent EachMax Sector at 20% Cap
5 stocks$1,20020%1 stock (20%)
6 stocks$1,00016.7%1 stock (16.7%)
8 stocks$75012.5%1-2 stocks (12.5-25%)
10 stocks$60010%2 stocks (20%)
12 stocks$5008.3%2-3 stocks (16.7-25%)

More stocks mean thinner slices. Find the sweet spot where you can track each name without going crazy.

Key-Points Equal Weights = Equal Risk Control

When every position is the same size, no single stock can ruin your results. This also removes the stress of deciding which stock deserves more money.
