buy Haio again and wait for dividend

since i am going for holidays next week, today i bought in Haio at RM7.5. good that won't look at it for 1 whole week. i think will just wait to get dividend

Haio in at RM7.08

Last week i dashed in to buy Haio at RM7.08 after thinking that the dividend yield coupled with the growth is worth for me to buy in at such price. subsequently, for next few days it was trading at RM7.04. I originally thought its surge in price has tapered off. i am wrong. Today it is as high as RM7.6

Now , is it still worth to buy more shares now?

haio shooting through the roof

The stock is traded RM6.45 today. it has risen more than 55% since my first purchase at RM4.15 few months ago. Even at then some people told me the stock is expensive and not worth go in. Then it go to RM5, now it is > RM6. Now, people are telling me the stock is expensive again.

so the logic is

either the stock is too cheap previously (when people say it is expensive)
or it is super expensive nowadays (if what people say now is correct)

who is correct? as investor, how should we digest this? given current time, would u buy in?
