#4 short on this over extended OTC ticker. Checked on the overnight borrow fees while away on holiday, and discovered that TZ had jacked up the cost from about $3 per night for 300 shares to over $80 per night (an increase of 2500% in one day). By the time I discovered this, I had paid around $900 in borrow fees, was forced to exit for a bigger loss than expected. Didn’t downsize as it kept going higher on the 2nd, as I had gone to bed early for work the next day.
