If you have a bad feeling about an investment, why would you stay in the investment? Investments are supposed to make you feel good, not bad.
SEEK is a share-printing company with cheap, bogus products (shoddy, poorly constructed websites with almost zero users), and it will eventually return to triple zeros, sooner rather than later.
I'm not gonna tell you what to do, that is for you to decide. However, 20% losses in a day will happen more often than 20% gains in a day. If you are wagering more than you can afford seeing wiped out, then you need to think this thing through carefully.
You might get lucky and have a 20% up day tomorrow. If you do, you'd be wise to take a profit. If there is a 20% down day tomorrow, it is unlikely SEEK will see .003 ever again.
