Kind of. Parsing the paperwork generates an answer—it seems that Trump has sold his stocks—but not a complete one, and in the end serves as a demonstration of the inadequacy of Trump’s current disclosures as a way of actually understanding his finances.

The section of the financial-disclosure paperwork listing the president’s stocks doesn’t exactly show what he currently owns. Rather, it shows all of the assets that were either worth at least $1,000 when the form was filed or that generated at least $200 in income during the reporting period the form represents—in this case, the previous 12 months. Counting listings for the same company in multiple brokerage accounts as separate holdings, Trump’s forms list 249 assets that meet these criteria. This includes Boeing, located halfway down page 38.

But that doesn’t mean he still owns stock in Boeing. The forms list the value of Trump’s Boeing stock as “None (or less than $1,001)” with income of between $5,001 and $15,000, which means Trump currently owns less than $1,001 in Boeing stock, but earned between $5,001 and $15,000 from stock in the company (perhaps from its appreciation, or perhaps from selling it) over the previous 12 months. That’s compared with a value of $50,001 to $100,000 and income of $1,001 to $2,500 on his 2016 report.

Based on those figures, it’s reasonable to conclude that Trump sold off his stock in Boeing since he filed his previous disclosure forms in May 2016. Indeed, most of his stocks in publicly-held companies are now listed as being held at values of less than $1,001, which suggests that he no longer owns them (although it’s possible he still has some stocks, just in much smaller amounts).

Assuming he did sell his stocks, when did he sell them, and to whom? That’s impossible to determine based on the financial-disclosure forms. Theoretically, that information should be listed in Part 7 of the paperwork, labeled “Transactions.” However, there are several caveats that, in Trump’s case, appear to have enabled him to leave the section entirely blank.

To begin with, an official doesn’t have to report “transactions that occurred when you were not an employee of the United States Government.” This means that, for seven of the 12 months the forms document, Trump was not obligated to disclose any of his stock transactions. In other words, if Trump did sell his stocks before taking office, there’s no way, using only the disclosures Trump is required to file, of confirming when or to whom.

For transactions that do happen while an official is in office, the OGE requires that he or she document purchases or sales of more than $1,000. But there are exceptions to that requirement as well. As an FAQ on the OGE’s website explains, even if the sum total of the sales is greater than $1,000, all that matters is the size of the individual transactions. As such, a person who wanted to maintain secrecy could buy or sell large quantities of stock without having to disclose the transactions as long as each was below the threshold. On top of that, there are exceptions for “transactions that occurred solely by and between you, your spouse, or your dependent children” or assets held in a trust that could easily provide ways around disclosure requirements. That means Trump could theoretically have transferred stocks to his wife, one of his younger children, or a trust in order to avoid having to report the transactions.
