I executed a very small day trade today. I purchased put warrants on the Hang Seng Index (code 5441) at the opening of trading and sold them back in mid afternoon. Entry price was HK$0.205. Sale price was HK$0.213. Given that the amount involved was very small ( I am not inclined to invest meaningful sums of money on something as speculative as day trading), the profit was correspondingly small. After transaction costs I made enough to take Mrs Trainee investor out for a nice dinner so long as we don't want wine with the dinner.
Needless to say, the small profit made on this trade was considerably less than the declines in value of my other investments today.
