It's not a stupid question. Actually, a lot of people don't know where to start when it comes to playing in the stock market. In a way it's not off-topic since you asked about blue chips which you typically hold long term compared to the second liners and the chupita stocks.
hi! i have a stupid question: where can we buy blue chips online?
im also looking for venues to invest some of my savings. ^^
You have two ways of going about this either through a red-blooded broker or through online systems. The advantage of going through a broker is the input and the guidance they can provide but if you're shy (which is typically the case) you can go to these sites: firstmetrosec.com.ph, bpiexpressonline.com, citiseconline.com. there maybe others (i doubt it) but these are the ones worth their salt.
Now since you mentioned you wanted to invest in blue chips i'm assuming you won't be trading actively but rather like a wham-bam-thankyou-m'am kind of thing where you just buy and forget about it. I suggest you go through a live broker so that you can be given the proper recommendations. Log in to pse.com.ph for the FAQ and a list of the member brokers and their contact numbers. Hope this helps
