SoFi Securities Systematically Inflated My Cost Basis Across Thousands of Trades — I Have the Screenshots

July 13, 2026

I have been a stock trader for years. I understand how markets work. I understand limit orders. I understand cost basis. What I do not understand is why SoFi Securities repeatedly showed me cost basis figures that were significantly higher than what I actually paid — across thousands of trades over the past two to three months — causing me to sell winning positions as if they were losing ones.

This is my documented account. The screenshots exist. The demand letter has been sent. And I am publishing this because I suspect I am not alone.

What Happened

My trading practice is simple and consistent. I place limit orders to lock in my purchase price. I sell my entire position before rebuying. I buy once per position. There is no mathematical reason my cost basis should ever differ from my single confirmed purchase price.

Yet repeatedly, SoFi displayed cost basis figures dramatically higher than what I actually paid.

The most recent and clearest example: I purchased shares of BATL at limit order prices between 1.70 and 1.80 per share. The next day I logged into my SoFi account to find my average cost displayed as 3.80 per share — more than double what I actually paid. The stock was green. I should have been profitable. Instead SoFi was showing me deep in the red.

This is not an isolated incident. SRXH — I purchased 2,000 shares at 0.09 per share. SoFi showed my average cost as 0.12 to 0.13 per share the following day. DVLT — same pattern. Across thousands of trades over multiple months, SoFi consistently inflated my cost basis, making profitable or breakeven positions appear to be significant losses.

The Real Damage

The inflated cost basis numbers were not just an inconvenience. They caused real financial harm.

Every time I logged in and saw myself deep in the red on a position I had just purchased at a locked-in limit price, I made a rational decision based on the data in front of me — I sold to stop the bleeding. What I did not know was that the data was wrong. I was selling winning positions as losers. I was locking in real losses based on SoFi false numbers.

Across thousands of trades this pattern caused me thousands of dollars in unnecessary losses. Two weeks ago I withdrew every dollar from my SoFi account. I will never return.

The Legal Issues

A formal demand letter dated July 13, 2026 has been sent to SoFi Securities demanding 50,000 dollars in compensatory and punitive damages and a full accounting of every affected trade. Formal complaints have also been filed with FINRA, the SEC, the CFPB, and the Florida Office of Financial Regulation.

SoFi conduct as documented potentially violates Securities Exchange Act Section 10(b) and SEC Rule 10b-5, prohibiting fraudulent and manipulative practices in connection with securities transactions. FINRA Rule 5310 requiring best execution on limit orders. FINRA Rule 4511 prohibiting falsification of account records. And the Florida Deceptive and Unfair Trade Practices Act prohibiting unfair and deceptive conduct causing financial harm.

SoFi Response

SoFi Securities and their CEO have been publicly called out on social media with documented evidence tagged directly. As of the publication of this article they have not responded.

Silence is not an answer.
