Find a reliable execution platform by comparing the best stock brokers for active traders.

Key Takeaways

• Never risk more than 1-3% of your account on a single options trade.
• Monitor your portfolio theta, delta, and vega at the portfolio level — not just per trade.
• Undefined-risk positions (naked options, strangles) require more margin and experience — start with defined risk.
• The biggest options risk is over-leveraging — 100 shares via options costs 5-10% of owning the shares, tempting oversizing.

Practical Tips

• Use a position sizing calculator that accounts for max loss (not just premium at risk).
• Keep total portfolio theta under 0.5% of net liquidation value per day.
• Have a 'blow-up prevention' rule: if total account delta exceeds 300-500, you're too directionally exposed.
