Sales Practices: DCA, Market Timing, and Late Trading

With the pricing and fee mechanics covered, you can now see three sales practices the exam tests: one that helps customers (Dollar-Cost Averaging), one that harms long-term shareholders (market timing), and one that is outright illegal (late trading).

What is dollar-cost averaging?

Dollar-Cost Averaging (DCA) is the practice of investing a fixed dollar amount at regular intervals regardless of the share price.

Mechanics:

• Fixed dollar amount per period (e.g., $500 every month)
• More shares purchased when prices are low, fewer when high
• Average cost per share is less than the average price per share over the period

Use cases:

• Variable annuity premium payments
• Mutual fund systematic investment plans
• Employer-sponsored retirement plan contributions

Limitations:

• Does not guarantee a profit
• Does not protect against loss in a declining market
• In a steadily rising market, lump-sum investing at the start outperforms DCA

Think of it this way: DCA reduces timing risk (the risk of investing everything at a market peak), not market risk (the risk of the market falling). If you had $12,000 to invest and the market only went up all year, investing it all on January 1 would beat spreading $1,000 per month. DCA wins in flat or declining markets where the $12,000 lump sum would have bought fewer shares at the start.

Exam Tip: Gotchas

• DCA does NOT guarantee a lower cost than lump-sum investing. In a steadily rising market, lump-sum wins.
• DCA's benefit is reducing timing risk, not guaranteeing returns. A question that says "DCA guarantees a profit" is wrong.
• Average cost is less than average price under DCA because more shares are bought at lower prices. This math relationship is a testable fact.

Is mutual fund market timing illegal?

Market timing is short-term in-and-out trading of mutual fund shares to exploit stale NAVs.

Typical pattern:

• Arbitrage between the U.S. market close (4:00 p.m. Eastern Time (ET)) and the next Asian market open for a fund holding Asian equities
• Rapid buy-sell cycles within days or weeks

Regulatory status:

• Not illegal per se but harms long-term shareholders by:
  • Diluting returns (the timer captures value other shareholders would have received)
  • Forcing the fund to maintain higher cash balances to meet redemptions
• Mutual funds routinely impose:
  • Short-term redemption fees (typically on shares held less than 30-90 days)
  • Trading restrictions (frequent-trading policies that block rapid round trips)

Exam Tip: Gotchas

• Market timing is legal but restricted. Funds may impose redemption fees and block frequent traders through their own frequent-trading policies.
• Market timing harms long-term shareholders by diluting returns. This is why funds police it even though it is not illegal.
• Short-term redemption fees are NOT counted as part of the FINRA 8.5% sales-charge cap. They are a separate tool for deterring market timing.

Why is late trading of mutual funds illegal?

Late trading is illegal. It is the practice of placing a mutual fund order after the fund's pricing time (typically 4:00 p.m. ET) but having the order priced at that day's NAV.

Why it is illegal:

• Violates Rule 22c-1 (forward pricing)
• The order must receive the next-computed NAV, not a known stale price
• Allows the late trader to take advantage of after-hours news or market movements

Historical context:

• Late trading was a central abuse in the 2003 mutual fund scandal
• Broker-dealers can be sanctioned for failing to enforce cutoff times
• Principals are expected to supervise order flow around the 4:00 p.m. ET cutoff

Think of it this way: Late trading is like being allowed to bet on yesterday's horse race today. If a news event causes a fund's holdings to jump after the market closes, a late trader could buy at the pre-news NAV and lock in a guaranteed gain. Rule 22c-1 prevents that by requiring the order to receive tomorrow's (post-news) NAV.

Exam Tip: Gotchas

• Late trading is illegal. Market timing is restricted but legal.
• Rule 22c-1 forward pricing is the rule that prevents late trading. An order placed at 4:02 p.m. ET gets tomorrow's NAV, not today's.
• Principals are responsible for enforcing the 4:00 p.m. ET cutoff. A broker-dealer that fails to supervise order timing can be sanctioned even if the firm did not originate the late trade.
