A San Diego retiree has filed a court petition to compel arbitration against Morgan Stanley and his financial advisor, Nicholas S. Westendorf. The legal action stems from allegations that a covered-call investment strategy resulted in the loss of more than $5 million in stock.

Why it matters

This dispute highlights the risks associated with complex options-based investment strategies in retail brokerage accounts. It serves as a reminder for investors to verify that their portfolio strategy aligns with their personal risk tolerance and long-term financial goals.

The petition involves an alleged loss of more than $5 million in stock value. This figure represents the total amount the retiree claims was stripped through the use of a covered-call strategy.

The players

Michael J. Massery

A San Diego-based retiree and the claimant who initiated legal action regarding his investment losses.

Morgan Stanley

A global financial services firm that provides brokerage and investment advisory services to individual households.

Nicholas S. Westendorf

A financial advisor associated with Morgan Stanley's brokerage unit.

The details

The claimant, Michael J. Massery, is seeking to force the dispute into the Financial Industry Regulatory Authority (FINRA) arbitration system. A covered-call strategy involves selling call options on stocks already held in a portfolio to generate premium income, but it effectively caps the upside potential of those shares. If the underlying stock price rises significantly, the investor may be forced to sell the stock at the strike price, which the claimant alleges resulted in the substantial loss of his holdings.

Money Landscape

The Financial Industry Regulatory Authority arbitration system serves as the primary forum for resolving disputes between individual investors and their brokerage firms. This case follows the standard path for investors seeking redress against large institutional brokers.

Investors who use complex options strategies like covered calls should regularly review their account statements to confirm that trading activity matches their authorized risk profile. Discuss your portfolio strategy and any concerns about specific trading activities with a qualified financial or tax professional.

The takeaway

This case underscores the importance of monitoring how specific investment strategies, such as covered calls, impact your overall stock ownership and upside potential. Review your brokerage statements for any unauthorized activity or strategies that diverge from your established financial plan.
