A day trader in Arizona has started a GoFundMe page asking fellow traders to help him pay off a $US100,000 debt to E-Trade after a disastrous short bet on a biotech stock.

Joe Campbell, a 32-year-old small-business owner from Gilbert, Arizona, created the page after a huge loss on KaloBios Pharmaceuticals.

Campbell says he sold about 8,400 shares short at an average price of a little under $US2 on Wednesday.

He told Business Insider that he estimated the stock was worth $US1.

Campbell also told Business Insider in a telephone interview that he normally wouldn’t feel comfortable holding a position overnight. However, he felt like the company was worthless, and for good reason.

Just last week, KaloBios said it was going to wind down operations and discontinue two of the drugs it had been developing.

After placing his trade, Campbell says he went into a two-hour meeting. When he came out, a friend asked him if he was OK. That’s when he learned the stock had surged. He says he lost his $US33,000 and is now in the deep red.

An investor group, which included controversial biotech CEO Martin Shkreli, bought more than half of KaloBios’ outstanding shares, sending the stock price up more than 600% in the after-hours session.

The stock was last trading up more than 500% at $US12.56 per share.

Campbell said that he feels “sick to his stomach” and that he’s just trying to “live a normal day.”

Currently, Campbell has raised over $US1,500.

Business Insider has reached out to E-Trade for comment and will update if we hear back.

Here’s a copy of Campbell’s story posted on his GoFundMe page:

Hello to all you traders out there. I’m starting this page out of the recommendation of other traders in the community. I hesitated on doing this but I literally owe Etrade $US106,445.56 as of this moment what would you do if you were in my situation? I’ll do whats needed and sell what I have to get them paid but if someone feels my pain and is willing to help out—who am I to say no? If you don’t want to donate I understand, at least read my story of what happened today and protect yourself from the same happening to you! This is a terrible lesson for me but if this helps just one person than I’m happy I wrote this. I’m a fairly new trader, been trading since about March of this year. I have learned alot about the community and trading…well not enough about trading as you will soon hear. I have a fairly small account, but its over PDT. As of this morning it was $US37,000. I keep it small because I wanted to manage risk, the most I can afford to lose is what I have in the account….$US37,000. When I get some profits I take them out of the account because I wouldn’t want to lose more than $US37k. I was holding KBIO short overnight for what I thought was a nice $US2.00 fade coming. At the close of the bell I saw the quote montage clear out and figured today there was no action after hours in the stock. So I went to my office for a long meeting. I got out of the meeting and saw a message from one of my buddys, he asked if I was OK since I was short KBIO….my heart dropped. “Shoot did I blow up my account, everything I worked for? I don’t want to lose all $US37,000 that would be terrible.” —It was much worse. The stock was at $US16 and my account was negative over 100k. I figured it was a mistake, Etrade would never let that happen, they must have cut the position when my account got to $US0….nope. I immediately called them and they confirmed I still owned all the shares. He says that it got out of hand too fast for them to cover me, he says that all he can do right now is cover. I was devistated. I asked him to cover at $US16 and he waited trying to find me a good exit. I told him to do it asap and the fill was around $US18.50 avg. At the moment not only is my $US37k gone, but I now owe ETrade the negative balance of over $US106k. I always knew I could blow up an account and I was financially able to “afford” to lose the $US37k. Never in my wildest dreams did I imagine that Etrade would NOT have some sort of stop or circuit breaker in place that would automatically cut a position if the account went to $US0…..how could they ever let it get to -$US144k loss on a account that small! Also, why did I have to call them to find out what was going on, why did they not alert me or call me when it went neg??? I’m never one to ask for a handout and honestly I’m kinda not sure if I should post this but here we go. I’m sure it will cause lots of controversy on whether or not I deserve even a $US1 donation but it doesn’t hurt to ask. Anything you traders can do to help me get a little out of this hole would be a blessing for me. Anything donated will go 100% to simply paying Etrade some of this $US106,445.56. My plan moving forward is to liquidate mine and wife’s 401k’s and try work out a payment plan with Etrade. I’m also going to ask them to help out in some way…thats a longshot. I will pay them and be back trading….only with set stops this time. What an expensive lesson that was. I hope my story helps someone else from the same. Here are screenshots of the damage.
