Hello A bro,
Paiseh, I was out to bring my son cycling.
W being the "LAO JIAO" here probably answered your question, better than I can

... he is super experienced. I am learning from him everyday. His musings on the TOL and AAR are always good reads

Just to add a few more points.
Singapore market is like a tofu market, goes up and down with the US market. No exactly day to day.. but overall trend is important.
If you like mid-caps, say Ezra (Musicwhiz's favorite stock), on follow thro' day, it was 51cts. Now it is around 1.30.
Always choose the strongest company in the sector that you are interested in. For eg. Wilmar would be the leader in the palm oil group, just like UOB is the leader among the banks.
When I say just whack, I was referring to the strongest companies as mentioned above and Winston is correct, major funds typically buy only index stocks cos' they have so much money, buying pennies will cause the stock to sky rocket.
When fund mgrs start to buy, they will leave clues in the price/vol action of your stocks. Similarly, when they sell, you will know too

I don't trade stocks with no earnings, stocks like lottvision or crap stocks like biosensors are punters favorite, I rather not touch them. Trading them is like crossing a traffic junction blindfolded. Some days you can get thro' and make some money, but one wrong move and you end up in the ICU
I hope this helps.
Cheers,
mm
